How to Make Sourdough Discard Banana Bread
With no rise time needed, you'll have this delicious loaf ready in no time! See the full recipe with detailed directions at the bottom of this post.
- Step 1: In a small bowl, mix together the flour, baking soda, and salt. Set aside.
- Step 2: In a large bowl, combine the mashed bananas, sourdough discard, sugars, and egg. Whisk to combine. Add the melted butter and mix until smooth.
- Step 3: Add the flour mixture to the bowl of wet ingredients and mix until just combined and no dry spots remain. Pout the batter into the prepared baking pan.
- Step 4: Bake for 60-65 minutes, or until a toothpick inserted in the center comes out clean.
Expert Baking Tips
- Mashing the bananas completely will give you a much smoother texture. I find larger banana chunks to be an unwelcome texture here.
- If you're adding chocolate chips, fold them in after you've mixed in the dry ingredients.
- The turbinado sugar on top is optional, but adds nice crunch and a little extra sweetness.

Easy, delicious, great texture.

We can only eat so many bananas, I have been cutting them up and freezing them for my smoothies. However this seems like a much better idea. One question, under substitutions it reads...
Use active sourdough starter - To do so, omit the yeast ....
I don't see yeast in the recipe, am I missing something?
Jessica Vogl says
Oops! Typo! I'm fixing it now. If you want to use active starter, you can. To do so, you would replace the sourdough discard with active starter (200g). All other ingredients and directions remain the same.
Diane says
Can this be baked as muffins? If so, I assume for about 25 minutes?
Jessica Vogl says
I haven't tried it, but I assume that would work!
Jamy says

I just made this banana bread and it is so good! The flavor and texture are perfect. I did sub Bob’s Red Mill Egg Replacer and Earth Balance plant butter to make it vegan. I also added Enjoy Life mini chocolate chips, and a big handful of unsweetened shredded coconut. It’s delicious!
