Make this easy, soft, and flavorful sourdough banana bread using your sourdough discard. This no-waste recipe transforms overripe bananas into a delicious quick bread perfect for breakfast or a cozy snack.

Ingredients

Scale
  • 1 cup (227g) ripe mashed bananas (about 3 large)
  • 1/2 cup (113g) unsalted butter, melted
  • 3/4 cup (150g) granulated sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 cup (120g) active sourdough discard (unfed starter)
  • 1 3/4 cups (210g) all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 teaspoon ground cinnamon
  • 1/2 cup (60g) chopped walnuts or chocolate chips (optional)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan, or line it with parchment paper.
  2. In a large bowl, mix the mashed bananas, melted butter, sugar, egg, and vanilla extract until just combined.
  3. Stir in the sourdough discard until the mixture is smooth.
  4. In a separate medium bowl, whisk together the flour, baking soda, salt, and cinnamon.
  5. Gradually add the dry ingredients to the wet ingredients. Mix only until the flour streaks disappear. Do not overmix.
  6. Gently fold in any optional mix-ins like walnuts or chocolate chips.
  7. Pour the batter into the prepared loaf pan.
  8. Bake for 50 to 65 minutes, or until a wooden skewer inserted into the center comes out clean. Baking time varies based on oven and banana moisture content.
  9. Let the bread cool in the pan for 10 minutes before carefully transferring it to a wire rack to cool completely before slicing.

Notes

  • For the best flavor and moisture, use very ripe, spotty bananas.
  • If you do not have discard, you can substitute it with 1/2 cup of plain yogurt mixed with 1/2 cup of milk, though the tang will be reduced.
  • This bread stays soft for days when stored tightly wrapped at room temperature.
