How to Make Sourdough Discard Banana Bread
-
Preheat: Set your oven to 350°F (175°C) and grease a loaf pan. This ensures your banana bread bakes evenly and doesn’t stick.
-
Combine Dry Ingredients: In a bowl, mix together the all-purpose flour, granulated sugar, and baking soda. This blend will give your bread the structure it needs for that perfect crumb.
-
Mash and Mix: In another bowl, mash those ripe bananas until smooth. Stir in the sourdough discard, vegetable oil, and eggs until well combined. The riper the bananas, the sweeter your loaf will be!
-
Combine Wet and Dry: Gently fold the wet ingredients into the dry ingredients until just blended. Be careful not to over-mix; a few lumps are okay.
-
Pour and Bake: Pour the batter into your prepared loaf pan and pop it in the oven. Bake for about 50 minutes or until the top is golden brown and a toothpick inserted comes out clean.
-
Cool: Allow the bread to cool in the pan for a few minutes before transferring it to a wire rack to cool completely. This waiting period enhances the flavors and makes slicing easier.
Optional: Slice warm and enjoy with a pat of butter for a delightful treat!

Sourdough Discard Banana Bread Recipe FAQs
What type of bananas should I use for this recipe?
Absolutely! The riper the bananas, the better; they should have brown spots and feel soft to the touch. Overripe bananas add the sweetest flavor and ultimate moisture to your Sourdough Discard Banana Bread. If you can’t use overripe bananas, consider substituting them with applesauce for a lower-calorie alternative.
How should I store Sourdough Discard Banana Bread?
For the best storage, keep your banana bread in an airtight container at room temperature for up to 3 days. If you prefer to enjoy it longer, you can refrigerate it, but it is best consumed within a week.

What if my banana bread doesn’t rise?
If your Sourdough Discard Banana Bread doesn’t rise properly, it could be due to using old baking soda or insufficient mixing.

Additionally, avoid over-mixing the batter and allow ample space for rising in your loaf pan.
Are there any dietary restrictions to consider?
Very! If you’re looking for vegan options, you can substitute the large eggs with flax eggs (mix 1 tablespoon of flaxseed meal with 2.5 tablespoons of water; let it sit for a few minutes) or applesauce for moisture. Keep in mind to check all brands for allergens, as ingredients like nuts or gluten are common in many kitchens.
