Sourdough Discard Banana Bread quickly became one of my favorite ways to use extra sourdough starter sitting in the fridge. The first time I baked this loaf, the kitchen filled with the warm smell of ripe bananas, vanilla, and sweet brown sugar.
When I sliced into it, the texture was incredibly soft and moist, with little pockets of melted chocolate chips in every bite. The sourdough discard gives the banana bread a subtle tangy flavor that balances the sweetness perfectly without overpowering the classic banana taste.
What I love most about this recipe is how simple it feels to make. Everything comes together with basic pantry ingredients, yet the final loaf tastes bakery-worthy. It is the kind of comforting recipe that works for breakfast, an afternoon snack, or even dessert with a cup of coffee.
If you have over-ripe bananas and sourdough discard waiting to be used, this recipe is one you will want to make again and again.
Key Ingredients in Sourdough Discard Banana Bread
3 over-ripe bananas, about 1 1/2 cups
2 large eggs, lighly beaten
½ cup white sugar
½ cup brown sugar
½ cup vegetable oil
1 teaspoon vanilla extract
200 grams sourdough discard, about 3/4 cup
1 â…› cup all purpose flour
2 teaspoons baking powder
1 teaspoon salt
½ cup mini chocolate chips or nuts, optional
How to Make Sourdough Discard Banana Bread Step-by-Step
-Preheat your oven to 425 degrees Fahrenheit. Prepare a loaf pan by lining it with parchment paper or lightly greasing it with cooking spray. This makes removing the banana bread much easier later.
-In a medium bowl, mash the over-ripe bananas until mostly smooth. Add the lightly beaten eggs, white sugar, brown sugar, vegetable oil, and vanilla extract. Stir everything together until fully combined and creamy.
-Add the sourdough discard to the banana mixture. Stir gently until just combined. The batter will become smooth and slightly thick.
-In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Fold the dry ingredients into the wet ingredients carefully. If using mini chocolate chips or nuts, stir them in at the end. Avoid overmixing because it can make the bread dense.
-Pour the batter into the prepared loaf pan. Bake at 425 degrees for 10 minutes first. Then reduce the oven temperature to 350 degrees and continue baking for about 50 minutes.
-Test the center of the loaf with a knife or toothpick. If it comes out clean, the banana bread is ready. If not, bake for another 5 to 10 minutes until fully cooked through.
-Let the bread cool in the pan for 10 minutes before transferring it to a cooling rack. The loaf slices best once slightly cooled, although it is hard to resist while still warm.
