When my husband came home with a loaf of cheap white bread from the grocery store, I’m pretty sure smoke came out of my ears.

I did remind him that I’m That Sourdough Gal (hello?!), but he had a fair point. He needed cheap white bread from the store to make authentic pimento cheese sandwiches for the Masters. Regular artisan sourdough bread wouldn’t do.

Challenge accepted.

With the help of over 65 recipe testers and countless kitchen experiments, I set out to develop a sourdough sandwich bread that’s as soft and squishy as Wonder Bread but infinitely better (and gut healthy!).

The final result? A perfect 100% “I’ll make this again” score from testers and bread so good your kids won’t even ask you to cut off the crust.

“This bread is incredible. This is the second time I’ve made the second version of this recipe. My husband and 3-year-old literally ate this loaf in less than 36 hours.” –Recipe tester from Pike Creek, Delaware

Baker’s Timeline

Here’s a baker’s timeline to help you plan your bake:

Day 1
9amMake stiff sweet starter & tangzhong
8pmMix dough, begin bulk fermentation
Day 2
7amShape dough, place in pan for second rise
6:30pmBake bread

Note: Timeline based on 73°F (23°C) kitchen. For warmer homes, everything happens faster. For cooler homes, allow more time. The dough is very forgiving – focus on visual/texture cues rather than exact timing.

If your home is too warm for an overnight bulk fermentation – or you’ve made this recipe and the loaf was overproofed by morning – I suggest flipping the timeline:

The Recipe Testing Journey

This recipe testing journey was definitely a journey. It took many attempts before I got to a recipe draft worth sharing. Feedback from over 65 recipe testers guided me to a second draft that was out of this world.

I could not do it without all of you – you truly are the reason this recipe exists!

Watch the entire recipe testing journey here.

Initial Recipe Testing

Before I sent any recipe drafts to the testers, I needed to have a recipe worth testing. And it took a few attempts to get to that point.

I knew I wanted a tangzhong in the dough to help get that squishy, soft texture. So to start, I adapted my hot dog bun recipe, developed with Samantha from Healing Slice, to land on an initial attempt.

The first loaf was too dense and way too sour, so I went back to the drawing board and adjusted many of the measurements.

recipe test 1
My first attempt at making sourdough sandwich bread that resembled storebought white bread.

The second loaf stuck to the Pullman pan’s lid, which was a huge bummer. But the loaf was not dense and super squishy, so I felt we were moving in the right direction. Still too sour, though.

recipe test 2
The second attempt – it stuck to the lid really badly, but the dough itself was much better than the last go around.

The third loaf incorporated a stiff sweet starter to hopefully solve the sour issue. I also made a few other tweaks to the ingredient amounts, like a little more honey and less oil.

recipe test 3
The third attempt – dough seemed really great but that dang Pullman pan lid was becoming my enemy.

This one also stuck to the Pullman pan’s lid, though not as badly. It was still light and squishy, and the sourness was cut way back. But I wasn’t happy with the lid consistently messing up the final result!

The fourth go looked the best when it came out of the oven; it was fluffy as can be, and the flavor was amazing. I sent this version to the recipe testers!

wonderbread recipe test 4
The fourth attempt – it turned out great, so I wrote the recipe and sent it off to the group of testers.

Recipe Tester Feedback: Version 1

When I sent out the first version of my sourdough Wonder Bread recipe to over 65 dedicated testers, the enthusiasm was immediate.

With an average satisfaction rating of 4.42 out of 5 and 95.5% saying they’d make it again, I knew the core concept was solid. One tester raved, “My husband can’t stop eating it!” while another shared, “Cannot wait to make this recipe again.”

A few photos from recipe testers:

However, the feedback revealed several key areas for improvement beyond just flavor.

The most significant issue was hydration – 38% of testers found themselves adding flour because the dough was “extremely wet and sticky.”

Also, nearly half the testers had to adjust timing because fermentation moved faster than expected, and 64% found the flavor too tangy for authentic Wonder Bread taste.

Despite these issues, the texture consistently impressed, with responses like “bouncy and airy” and “perfect” appearing throughout the feedback. I was on the right track, but needed to fine-tune.

Recipe Tester Feedback: Version 2

The second round of testing blew my socks off!!

The recipe got 4.69 out of 5 stars, and we achieved the ultimate goal: 100% of testers said they would make this recipe again! I almost cried when I saw that!

More importantly, we solved multiple technical issues simultaneously. The hydration problems decreased, sourness complaints dropped, and timing issues were largely resolved.

“I feel like this is the winning recipe.” –Recipe tester from Susanville, CA

A few small issues popped up, like those using Costco AP flour still needing to add more flour, but that’s an easy tip to add to the recipe notes. A few also noticed their loaf tops getting too dark, but tenting with foil toward the end is an easy remedy.

I also got feedback on exactly which process photos would be a huge help in the recipe card itself.

The journey through two comprehensive testing rounds, guided by incredibly detailed feedback about everything from dough hydration to fermentation timing, led us to a recipe that truly delivers on the promise of sourdough Wonder Bread.

Ingredients In the Sourdough Wonder Bread Copycat Recipe

Here’s a quick look at the winning ingredients:

  • Sweet stiff starter: essential for cutting down the sour, tangy flavor of sourdough. My initial tests used regular, liquid starter (equal parts flour and water), and the bread was way too sour.
  • Honey: Acts as a natural sweetener and helps create that soft, tender crumb. The honey also feeds the yeast and helps with browning. You can substitute with granulated sugar, but you may need to add 1-2 tablespoons more liquid.
  • High-protein bread flour: I’ve tested this with Ballerina Farms bread flour (14% protein) and King Arthur bread flour (12.7% protein) with excellent results. The higher protein content helps create structure while staying soft. If using Costco all-purpose flour, add about 25g more flour to the main dough.
  • Milk: Creates the tangzhong (flour paste) that makes this bread incredibly soft and helps it stay fresh longer. Any dairy or non-dairy milk works – testers had success with cashew milk and almond milk, too.
  • Avocado oil: Adds richness and helps keep the crumb tender. You can easily substitute with olive oil, sunflower oil, or any neutral oil you have on hand.
  • Water: Regular tap water works perfectly. The hydration level creates a slightly tacky dough that bakes into that perfect Wonder Bread texture.
  • Salt: Essential for flavor and dough structure. I use sea salt, but any salt without anti-caking agents will work great.
  • Butter: Just for brushing the hot loaf after baking – this creates that soft, glossy crust that mimics storebought Wonder Bread perfectly.

How to Make Sourdough Wonder Bread (Step by Step)

This recipe spans three days, but don’t let that intimidate you! Most of the time is hands-off fermentation.

Once you make it the first time, you won’t even need the recipe card other than to reference the ingredient list. It’s that simple.

Here’s exactly how to make the softest sourdough sandwich bread.

Day 1 (Evening): Prep Work

Make the Stiff Sweet Starter

The stiff sweet starter is the secret to reducing sourness.

In a small jar, combine 15g sourdough starter, 15g honey, 30g water, and 60g bread flour.

Mix until it comes together, then turn it out and knead it briefly until it forms a smooth ball.

Place it back in the jar, cover loosely, and let it ferment at room temperature overnight. By morning, it should have doubled (or tripled) in size and smell sweet and yeasty.

If you use a bigger jar than mine, it’ll also have a domed shape.

Make the Tangzhong

The tangzhong is a cooked flour paste that creates incredibly soft, pillowy bread that stays fresh for days.

In a microwave-safe bowl, whisk together 35g bread flour and 175g milk until completely smooth.

Microwave in 30-second intervals, stirring vigorously with a whisk between each round. For me, this usually takes 3-5 rounds.

tanzhong steps

You’re looking for it to thicken to a pudding-like consistency and reach 150°F (65°C).

sourdough sandwhich bread recipe 8

If you prefer, you can make this on the stovetop over medium heat, whisking constantly. Don’t walk away or it will overcook!

Cover and refrigerate overnight. The tangzhong can be made up to 2 days ahead.

You could also make it in the morning when you’re putting your dough together, but you have to wait for it to cool fully. That’s why I prefer doing it when I’m feeding my starter the night before.

Day 2 (Morning): Mix and First Rise

Mix the Dough

In the morning, it’s time to mix our dough!

In your stand mixer bowl, combine all of the stiff sweet starter, all of the tangzhong (straight from the fridge), 225g cold water, 75g honey, 25g avocado oil, 575g high-protein bread flour, and 12g salt.

Note: one of the recipe testers suggested mixing all of the liquids in the stand mixer before adding the dry ingredients. I didn’t find this necessary for my stand mixer, but it could help if your mixer isn’t as powerful.

Related: Ooni vs Bosch vs KitchenAid vs Ankarsrum: Best Stand Mixer for Sourdough

Start mixing on speed 1 (the lowest setting) for 1-2 minutes just to bring everything together. It will look shaggy and rough at first – that’s normal!

sourdough sandwhich bread recipe 7
The dough after 1-2 minutes at low speed.

Once the ingredients are incorporated, increase the speed to 2 and mix for 10-15 minutes.

The dough is ready when it passes the windowpane test – you should be able to stretch a small piece thin enough to see light through without it tearing immediately. In a Bosch mixer, this took me about 10 minutes; in a KitchenAid, it took me 33 minutes.

 windowpane

The finished dough will feel slightly sticky or tacky, but not overly so. It should hold its shape and pull away from the sides of the bowl.

If your dough is extremely wet, sloppy, or won’t come together after several minutes, add flour 1 tablespoon at a time. About 38% of the recipe testers needed to add a little extra flour due to humidity or flour brand differences.

No Stand Mixer? You can absolutely make this by hand! Mix initially for 3-4 minutes, then cover and rest for 30 minutes. Do a round of stretch and folds every 30 minutes until you achieve a smooth, elastic dough with at least a weak windowpane.

Bulk Fermentation (First Rise)

Transfer the dough to a lightly oiled 2-quart bowl. I do a super quick spritz of avocado oil spray. You don’t have to oil the bowl if you don’t want to – it just helps the dough come out more easily later on.

Cover and let rise on the counter for 8-12 hours. The timing depends on your kitchen temperature – in my 73°F (23°C) kitchen, it took exactly 11 hours.

first rise before after

You’ll know bulk fermentation is complete when the dough has noticeably increased in size (about 40% larger), feels puffy when gently poked, and has visible bubbles around the edges and underneath.

Once it reaches this point, pop the bowl in the refrigerator until bedtime. This slows down fermentation and makes the dough easier to handle for shaping.

Note: if the dough is perfectly ready right before bedtime, skip the refrigeration step!

Day 2 (Evening): Shape the Dough

Prepare Your Pan

If you’re not using a nonstick pan, lightly oil your 13×4 inch loaf pan.

I love the USA Pan 13×4 pan for its great results and the nonstick surface (it doesn’t use Teflon!). Even though it’s nonstick, I still do a super quick spritz of my avocado oil spray, just in case. It’s probably not needed, but it feels like a little insurance!

Shape the Loaf

Remove the dough from the fridge and turn it onto your work surface. I don’t need any flour to assist with shaping, but if you want, you can do a light dusting of bench flour.

Note: Bench flour is the flour scattered on a bench or counter during shaping to keep the dough from sticking. You can use all-purpose or bread flour for this. I don’t recommend rice flour as it’s so nonstick that it’ll prevent your dough from sticking to itself as you roll it up.

Using a rolling pin, gently roll the dough into a rectangle about 10 inches wide by 14 inches long. You want it slightly narrower than your pan width.

measured rectangle

Don’t worry about measuring the rectangle by any means – I’m just providing this as a general guideline.

Roll the dough up tightly like a jelly roll. Pinch the seam closed and roll your log a few times to even it out. Place the dough log seam-side down in your prepared pan.

Second Rise

Cover the pan and let rise on the counter overnight (8-12 hours). This is the final rise, so you want the dough to become very puffy and reach the height of the pan rim.

second rise before after

In my 73°F (23°C) kitchen, this took 11.5 hours. The dough should feel light and airy.

Day 3 (Morning): Bake Your Sourdough Sandwich Loaf!

Bake the Bread

Once your dough has reached the height of the pan, preheat your oven to 350°F (175°C).

sourdough sandwhich bread recipe 1
This dough is ready to bake!

Once preheated, bake the loaf uncovered for 40-45 minutes, until the internal temperature reaches 200-205°F (93-96°C).

The top should be golden brown – if it’s getting too dark before the internal temperature is reached, tent it loosely with foil for the remaining baking time.

The Finishing Touch

As soon as you remove the bread from the oven, brush the top with 1 tablespoon of butter. This creates that soft crust that’s signature to Wonder Bread-style loaves.

sourdough sandwhich bread recipe11

Let the bread cool in the pan for 5-10 minutes, then turn it out onto a wire rack.

Resist the urge to slice immediately! Let it cool completely (1-2 hours) for the best texture and easiest slicing.

Note: If you slice too early, you may get gummy areas, and the bread will then dry out and feel stale once it fully cools.

So squishy!

How to Store Sourdough Sandwich Bread

  • Room Temperature Storage: This sandwich loaf stays remarkably fresh thanks to the tangzhong technique. I love storing mine in a glass cake stand where it’s beautifully displayed, while the dome helps keep it fresh. Many bakers swear by adding a celery stick to the container – it helps maintain moisture and extend freshness even longer.
  • Freshness Timeline: The bread is absolutely perfect on days 1-2, still delicious on day 3, and starts to show signs of staling on days 4-5. The texture remains softer than most homemade breads throughout this time.
  • Alternative Storage: My favorite brown paper bread bags from Sis & Co Collective work wonderfully for storage. They’re also great for gifting!
  • Freezing for Longer Storage: If you don’t plan to finish the loaf within 4-5 days, slice it up and freeze the individual slices in a freezer bag. This way, you can grab exactly what you need without thawing the whole loaf.
  • Reheating Frozen Slices: For soft, fresh-tasting slices, microwave frozen pieces for 10-15 seconds. For toast, pop the frozen slices directly into the toaster – no thawing needed!

DO NOT REFRIGERATE! The fridge will actually make your bread stale faster. Refrigeration accelerates retrogradation – the process where starch molecules reorganize and become firm, creating that stale texture. Room temperature storage keeps the starches in their soft, fresh state much longer.

Ingredient Substitutions

  • Honey: Can be substituted with an equal weight of granulated sugar. If using granulated sugar, add 1-2 tablespoons extra liquid to compensate for moisture loss.
  • Avocado oil: Easily swap with olive oil, sunflower oil, melted coconut oil, or any neutral-tasting oil. Multiple testers successfully used olive oil with great results.
  • Milk (for tangzhong): Any dairy or non-dairy milk works beautifully. Testers had success with cashew milk, almond milk, and regular dairy milk. Just make sure it’s unsweetened and unflavored.
  • High-protein bread flour: King Arthur bread flour and Ballerina Farms both work as written (I tested both). If using all-purpose flour (like Costco brand), add an extra 25g flour to the main dough for proper structure.
  • Water: one tester used milk in the main dough instead of the water. This works fine, but the final loaf will be more sour. If you want more milk in the main dough, I’d try half milk, half water.

FAQs

Can I make this recipe in a regular-sized loaf pan?

Yes! I created a calculator on this recipe post (right above the recipe card)! Just select your loaf pan size, how many loaves you want to make, and copy the new ingredient list.

Can I use regular starter instead of the stiff, sweet one?

Yes, you can! Just note that the resulting bread will be more tangy since you’re skipping the sweet stiff starter. Instead of making the sweet stiff starter, use 100g of your regular active sourdough starter (fed at 100% hydration – equal parts flour and water).

Then adjust the main dough: reduce cold water from 225g to 212g, and increase bread flour from 575g to 593g. These adjustments account for the different hydration levels between the stiff sweet starter and regular liquid starter, keeping the overall dough hydration the same.

Can I use a different oil instead of avocado oil?

Yes! Several testers successfully used olive oil, sunflower oil, and extra virgin olive oil in place of avocado oil with great results. Any neutral-tasting oil will work.

Can I substitute sugar for honey?

While honey provides both sweetness and helps with texture/moisture, you can substitute with an equal weight of granulated sugar. However, you may need to add 1-2 tablespoons of additional liquid to compensate for the moisture loss.

What about dairy-free milk substitutions?

Absolutely! Testers successfully used cashew milk and almond milk in the tangzhong. Any non-dairy milk should work fine – just make sure it’s unsweetened and unflavored.

Can I add an egg to the dough?

One tester added an egg and had success, though it will change the texture slightly, making it richer and more tender. If adding an egg, reduce the water by at least 25g to maintain proper hydration.

Why is my dough so sticky? Do I need more flour?

The dough is meant to be slightly sticky/tacky after mixing. However, some recipe testers needed to add between 1 tbsp and 1/4 cup extra flour due to humidity, flour brand differences, or kitchen conditions. Add flour gradually (1 tablespoon at a time) until the dough comes together.

My kitchen is warmer/cooler than 73°F (23°C). How do I adjust?

For warmer kitchens [76°F+ (24.5°C+)]: Reduce fermentation times and check dough earlier. The overnight rise on the counter will likely overproof your dough, so pop it in the fridge overnight. Bring it out in the morning and proceed with the second rise. For cooler kitchens (under 70°F or 21°C): Add 1-3 hours to each fermentation stage. Always go by visual cues – refer to the photos in the recipe card for help!

Can I pause the process at any point?

Yes! You can refrigerate the dough at any stage to slow fermentation. This is especially helpful after bulk fermentation or during the second rise if your timing gets off.

What if my dough is ready earlier/later than the timeline?

The timeline is a guide based on a 73°F (23°C) kitchen. Many testers had to adjust timing by several hours. Focus on the dough’s appearance and feel rather than strict timing. I’ve provided photos in this recipe post to help you compare your dough to mine!

Can I make this without a stand mixer?

Yes, but it requires more effort. Mix initially for 3-4 minutes by hand, then rest 30 minutes. Repeat with stretch and folds every 30 minutes until you achieve a smooth, elastic dough. The goal is still a weak windowpane.

Can I double the recipe?

Yes! Several testers successfully doubled or scaled up the recipe. Just ensure your mixer can handle the larger dough volume, and you may need to extend mixing time slightly.

Do you use the Pullman pan lid or bake with no lid?

The final recipe is for no lid, because it always stuck when I tested. But some testers used the lid and loved it. Many have suggested my particular lid may be faulty, but in any case, you don’t need the lid!

My loaf was still too sour for my liking. How can I make it even less tangy?

My first suggestion would be to baby your starter for 1-2 days before starting this recipe. Feed it from peak to peak, meaning you never let it deflate before refreshing it with a new feeding. That will cut down on any lingering acidity. My second suggestion would be to try flipping the timeline to shorten the rise times. Feed your starter in the morning, mix your dough before bed, shape the next morning, and watch it closely; bake it as soon as the dough reaches the lip of the pan. Perhaps that’ll shorten the second rise a little, leading to less tangy flavors.

My loaf overproofed – it has a lumpy surface and started deflating and caving in before baking. What do I do?

Try flipping the timeline for better control: feed starter in the morning, mix dough before bed, shape the next morning, and watch closely. Bake as soon as dough reaches the pan’s lip.
Prevention tips: Use cold ingredients (ice water, cold tangzhong) to prevent overheating during mixing. Remember: warm dough ferments faster.

Equipment

Ingredients

Stiff Sweet Starter

  • 15 g sourdough starter
  • 15 g honey
  • 30 g water
  • 60 g bread flour

Tangzhong

  • 35 g bread flour
  • 175 g whole milk

Main Dough

  • All of the stiff sweet starter from above
  • All of the tangzhong from above
  • 225 g cold water
  • 75 g honey or sugar
  • 25 g avocado oil
  • 575 g high-protein bread flour see Notes
  • 12 g salt
  • 1 tbsp butter for buttering the baked loaf

Instructions 

Day 1 (Evening)

  1. Make the stiff sweet starter: In a small jar, mix 15 g sourdough starter, 15 g honey, 30 g water, and 60 g bread flour until it forms a ball. Knead outside of the jar to fully incorporate the ingredients. Cover loosely and let ferment at room temperature until morning.

  2. Make the tangzhong: Mix 35 g bread flour and 175 g whole milk in a microwave-safe bowl. Microwave in 30-second intervals, stirring between each, until thickened and reaches 150°F (65°C). For me, it usually takes 3-5 rounds to finish. Cover and refrigerate until morning.
    tangzhong before and after

Day 2 (Morning)

  1. Mix the dough: In stand mixer bowl, combine All of the stiff sweet starter, All of the tangzhong, 225 g cold water, 75 g honey, 25 g avocado oil, 575 g high-protein bread flour, and 12 g salt. Mix on speed 1 (lowest speed) for 1-2 minutes until ingredients come together, then increase to speed 2 (a tiny bit faster) and mix for 10-15 minutes, or until dough reaches a weak windowpane. It takes about 10 minutes in a Bosch and upwards of 30 minutes in a KitchenAid, for reference.
    The dough will feel slightly sticky or tacky after mixing, but it should hold its shape. If the dough doesn't fully come together after a few minutes in the stand mixer, add additional flour in 1 tbsp increments.
    windowpane stage
  2. Bulk fermentation: Transfer to lightly oiled bowl, cover, and let rise on counter until evening (8-12 hours). At the end of bulk fermentation, the dough should have risen by about 40%, have lots of bubbles, and should be puffy when you tap the surface. (My BF took 11 hours; my home was 73°F/23°C and my dough was 75°F/24°C.) Once it reaches this point, put the bowl in the refrigerator until bedtime to slow down fermentation.

Day 2 (Evening)

  1. Shape the dough: If not using a nonstick bread pan, lightly oil it. Bring dough out of the fridge and turn it onto work surface (use a light dusting of flour to prevent sticking, if needed). Using a rolling pin, roll dough into rectangle slightly narrower than pan width (about 10" wide by 14" long).
  2. Roll up the dough tightly, pinch the seams on each end, and place your dough log seam-side down in bread pan.
    shaping dough
  3. Second rise: Cover and let rise on the counter, overnight, until very puffy and the dough is even with the height of the pan rim (approximately 8-12 hours). (My dough was ready after 11.5 hours in a 73°F/23°C environment.)
    Note: If your home is warmer than about 75°F (24°C), the dough will likely overproof by morning. I advise putting it in the fridge overnight and resuming with the second rise in the morning.
    second rise before after

Day 3 (Morning)

  1. Bake: Preheat oven to 350°F (175°C). Bake uncovered 40-45 minutes until internal temperature reaches 200-205°F (93-96°C). If the top of the loaf is getting too dark, cover with foil. Once done, immediately brush hot loaf with 1 tbsp butter. Cool in pan 5-10 minutes, then turn out onto rack. Cool completely before slicing (1-2 hours).

Notes

Flour Options:
  • Bread flour: Ballerina Farms (14% protein) or King Arthur unbleached (12.7% protein) – no adjustments needed
  • All-purpose: Costco AP flour – add 25g extra flour to main dough
  • Canadian options: Arva Mills Daisy flour or Boreal Organic All Purpose (Costco) work perfectly (thanks to follower Amanda Steele for this tip)
No stand mixer: If mixing by hand, the goal is still to achieve a strong dough with at least a weak windowpane – it will just take longer to get there. To avoid sore arms, I suggest mixing your dough initially for 3-4 minutes; then, cover and let rest for 30 minutes. Do a few rounds of stretch and folds, each 30 minutes apart. 
Using a smaller loaf pan: I created a calculator on the recipe post (right above the recipe card)! Just select your loaf pan size, how many loaves you want to make, and copy the new ingredient list.
Tangzhong: You can make the tangzhong up to 2 days in advance; keep in fridge. You can also make the tangzhong on the stovetop if you prefer. Heat over medium heat until the mixture reaches about 150°F and is thick like pudding. Ensure it is fully cooled before adding to dough!
Rise times: This dough is extremely forgiving. Don’t panic about getting the timing exactly right. The most important thing is that the dough is very aerated and puffy to the touch before baking. That said, the general timing provided is from my recipe testing in a 72-73°F (22-23°C) kitchen. If your kitchen is warmer, everything will happen faster. If your kitchen is colder, it will take longer.
Pausing the process: Feel free to put your loaf pan in the fridge to “pause” the process at any time. It will slow down fermentation and rise times. Resume when you’re ready by bringing the dough back to room temperature and carrying on with the next step.
Alternative timeline: Make starter/tangzhong morning of Day 1, mix dough evening of Day 1, shape morning of Day 2, bake evening of Day 2.

  1. Can you make this recipe vegan?
    And
    Can you use 100% wheat-free flour, with ancient grains like spelt, etc.? (notice not gluten free but wheat free)
    Thank you

    1. Yes all substitutions are listed in the substitutions section. And no, switching the flour will alter the recipe in a huge way and would likely need to be re-tested and tweaked to account for it.

    I am new to sour dough baking and I used the full recipe thinking I would just split it in half for two regular loaves. I made the stiff starter and then something came up and I could not start that day. put it in the refrigerator and started the next day. The first rise there was one big huge bubble on the top (no problem). I divided the dough and rolled it out that night to BF. The next morning it was way over the top of my loaf pans. I started to make foccacia with it and then I decided to just deflate it a little to fit it in the pan. Baked as usual, it turned out great despite all the problems Thank you for the recipe. I’m a fan!!

      1. Hmm, my starter came from the fridge, maybe that was my problem! I’m baking the loaves right now, but while my stiff sweet starter did grow, my dough has barely risen. I gave it 16 hours for the first proof (my kitchen is on the cooler side) and then tried shaping it into loaves to see if that would help. I bake artisan sourdough pretty often but I’m used to just grabbing my starter from the fridge and it hadn’t been fed for over a week probably.

    This is a family favorite, especially for my elderly parents who need a softer bread. What size are the weck jars that you make the sweet stuff starter in?

  4. Thank you for this recipe, this is my first stab at making a sourdough sandwich loaf.
    Couple of quick newbie questions for you:

    1) Should I cook right out of the fridge or should I let it get to room temp first?

    2) Should I run convection or not, if so, right off the bat or as some others state for good spring only after 15 Min?

    Thanks again for the recipe and the work it takes to get it to this point by you and the testers!

  5. I’m a newbie sourdough baker, (2+ months) learning so much all the time, and enjoying watching your videos and reading everything about sourdough! I’ve made about 6 regular sourdough boules, and most of them have turned out pretty decent, even though I’m not always sure what I’m doing! lol😅 I made the wonderbread copycat loaves today, hoping to use some for grilled cheese tonight for Halloween! Thank you so much for all your great information and tips. I still have a lot to learn, and can’t wait to try more of your recipes, but I’m pretty proud of myself for doing pretty well with the basics so far! Thank you again!

  6. What changes would I need to make for high altitude? I’ve made this recipe before and it didn’t work for me. I know hydration is the issue with high altitude and amount of starter, but not sure how to alter it. Thanks.

  7. My sweet stuff starter is not rising hardly at all. It is a little bubbly. I made a 2nd one just in case I missed something in the first but the 2nd did the same thing overnight. I used a healthy peaked starter, raw unfiltered honey, spring water & King Arthur organic bread flour. It sat on my counter for a few hours but it’s 66 degrees in here. I moved it to the oven with the light on and the light off to be warmer and only then did it get bubbly and rise a tad. Im not sure what I’m doing wrong. Any ideas why this happens?

    1. Yeah, it’s just too chilly. Keep it in a warmer spot and it’ll rise properly. You can try the microwave or oven with a cup of hot/near boiling water in the corner to create a warm environment if needed.

  8. Hi, can I use vegetable oil instead of the avocado oil? Just trying not to buy more stuff and use what I have. Thanks

  9. This recipe was ethereal. I was hesitant to make it because it seemed involved, but making it was extremely easy. I made it with the ooni, and it came out absolutely amazing. Lots of room for error. I cut down the sugar by 30% and I found it still a bit sweet.

    Made a triple batch of these today not cut yet. Did half fresh ground wheat. Almond milk substitute for grandson.

  11. Attempting sweet starter with a small amount for making 1 regular loaf size. My question is I forgot to knead it but stirred very well. Been on counter for 12 hours and has barely grown. Should I start again? My house isn’t very warm but I had a scarf around it under a regular light. Also I used my organic unbleached AP flour because I’m assuming the recipe for the main loaf I would use my quality bread flour.

    1. What’s your home temp? If it is showing signs of activity, it may just need a warmer environment to take off. But 12 hours for little activity is a long time. But again, the colder your environment, the longer things take. Also, the health of your starter can play into the timing – if there isn’t a super strong yeast population to begin with, it will take a lot longer.

    I use your recipe only I mix it by hand and do the stretch and folds. We absolutely love the tang of this bread as well as the softness. I keep it on the counter on a bamboo cutting board with a clear cover, and it keeps so well. I baked bread on Saturday and it was just as soft and fresh when we finished off the loaf on the following Sunday. Making your honey wheat with tangzhong this week. Thank you for your recipes!

  14. Help! I think I over proofed my second rise. They were in the oven with the light on and I forgot about them until it was time to go to bed. It’s been so cold in my house that I have to keep the oven light on to warm things up (both starter and bread proofing) but with a little kiddo running wild, everything feels out of sight out of mind. They are fluffing up over the rim of the loaf pans but it was tool late to bake so I put them in the fridge. Will they still work or should I turn them into something else?

  15. After mixing, can I shape and put the dough in a loaf pan and thus do only 1 rise? As in your Whole Wheat Super Soft Sandwich Bread recipe? Or does this recipe need the opportunity for a second rise?Thanks much!!
