Make this super moist sourdough discard banana bread using overripe bananas. This easy, one-bowl recipe delivers a soft, flavorful loaf with a subtle sourdough tang, perfect for reducing kitchen waste.

Ingredients

Scale
  • 1 cup (227g) ripe mashed bananas (about 3 medium)
  • 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
  • Optional additions: 1/2 cup chopped walnuts or chocolate chips

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, combine the mashed bananas, melted butter, sugar, egg, and vanilla extract. Whisk until smooth.
  3. Stir in the sourdough discard until just combined.
  4. In a separate medium bowl, whisk together the flour, baking soda, salt, and cinnamon.
  5. Add the dry ingredients to the wet ingredients. Mix gently with a spatula until just combined. Do not overmix; a few streaks of flour are acceptable.
  6. Fold in any optional nuts or chocolate chips if you are using them.
  7. Pour the batter into the prepared loaf pan and spread evenly.
  8. Bake for 50 to 65 minutes, or until a toothpick inserted into the center comes out clean or with moist crumbs attached.
  9. Let the bread cool in the pan for 10 minutes before carefully turning it out onto a wire rack to cool completely before slicing.

Notes

  • Use very ripe, spotty bananas for the best natural sweetness and moisture in this quick bread recipe.
  • For a richer flavor, substitute half the granulated sugar with packed light brown sugar.
  • This bread freezes well once completely cooled; wrap tightly in plastic wrap and then foil.
