Ingredients For Sourdough Discard Banana Bread
- Bananas- You want your bananas to be brown and spotty. The browner the better. When bananas get really brown, they get super sweet and intensify their banana flavor. Yellow or green bananas don't have the sugar that overripe bananas would have.
- Sourdough starter- inactive, meaning it hasn't been fed and likely is coming straight out of the refrigerator.
- Brown Sugar- For added sweetness. You could use granulated sugar instead.
- Baking Soda and Baking Powder- to help with leavening. Even though we are using sourdough starter, the baking soda and baking powder do most of the rising in the bread.
- Butter- To add fat and texture to the bread. If you would prefer this dairy free, you can substitute coconut oil instead.
- Vanilla Extract and Cinnamon- Adds flavor to the banana bread.
What is Sourdough Discard?
Sourdough starter discard is the portion of your sourdough starter that you are not feeding. When you are "feeding" your starter to make bread with, you feed it equal parts water, flour, and starter. You can't feed your entire starter, as it doubles and sometimes triples in size, and that's a lot of starter to have on hand! Keep your excess sourdough starter in a mason jar in the refrigerator.

How To Make Sourdough Discard Banana Bread
- Preheat the oven to 375 degrees.
- Butter a 9 by 5-inch loaf pan. Set that aside.
- In a medium bowl, mix together the all purpose flour, baking powder, baking soda, salt, and cinnamon. Set that aside.
- In a large mixing bowl, mash the bananas until they are pureed.
- Add the starter, melted butter, brown sugar, eggs, and vanilla to the bowl with the mashed banana. Mix well until fully combined.
- Add the dry ingredients to the wet ingredients and mix together until just combined. It's ok if there are a few lumps left in the batter.
- Pour the batter into the prepared loaf pan. Place the loaf pan into the preheated oven.
- Bake for 60 minutes or until a toothpick is inserted into the bread and comes out clean.
- Allow the bread to cool on a cooling rack before slicing. Enjoy!
Variations of This Recipe
- Add 1 cup of chocolate chips to make a chocolate chip banana bread.
- Mix in one cup of chopped walnuts for banana nut bread.
- Substitute ½ cup of coconut oil for the butter to make a dairy free banana bread.
- Swirl in ½ cup of peanut butter for a peanut butter banana bread.
- Add ½ cup of white chocolate chips or cinnamon chips for added sweetness!
Tips and Tricks
- Make sure your butter the loaf pan well. The bananas have a lot of sugar in them, plus there is brown sugar in the recipe, so it might stick. Butter is the best to use. I find that cooking spray causes the banana bread to stick.
- If the top of the bread starts to brown too quickly, tent aluminum foil over the top of the bread. This will slow the browning of the bread.
- This recipe makes one loaf, but you could separate this into small loaves if you have the tins. You could also easily double this recipe.
Frequently Asked Questions
