Preheat your waffle iron.Note: if you want a deeper nutty flavor, consider toasting your nuts in a saucepan over medium heat until fragrant (about 4-5 minutes). Let cool and proceed.
In a large bowl, whisk together 113 g unsalted butter and 340 g mashed overripe bananas. Then, add 1,000 g sourdough discard and whisk again. Finally, add 4 eggs, 2 tsp vanilla extract, 80 g brown sugar, 2 tsp cinnamon, and a Pinch of salt, whisking well.
Add 2 tsp baking soda and whisk vigorously. Within about 10 seconds, the batter will become aerated and fluffy—watch the magic happen! Quickly fold in 200 g chopped walnuts or pecans (or chocolate chips).
Pour the waffle batter into your waffle iron. Cook the waffles in your waffle iron according to the device's instructions.
Add any toppings you like, such as a pat of butter, a drizzle of warm maple syrup, sliced banana, extra chopped nuts, or a sprinkling of cinnamon. Enjoy!
These store best in the freezer. Layer the waffles on a sheet tray, each layer separated by a sheet of parchment paper. Flash freeze for 1 hour. Then, place the frozen waffles in a freezer bag. These keep well for months. To reheat, pop in the toaster!

Notes
340g of mashed overripe bananas is about 3-4 medium bananas. Do not panic about getting the grams exact. My bananas were on the larger side once, and I ended up with 485g of mashed banana – the waffles still turned out perfect. This is very flexible.
Adjust the Recipe: Scale the recipe up or down in 250g increments depending on how much discard you have.
Egg Substitute: Another baker has an egg allergy and substituted flax eggs for the eggs and said they turned out amazing! A flax egg is 1 tbsp ground golden flaxseeds mixed with 3 tbsp warm water.
