Print Friendly, PDF & Email


  • 1 cup sourdough starter (fed and active)
  • 1 cup mashed ripe bananas (about 3 medium bananas)
  • 2 eggs
  • 1/3 cup melted butter or vegetable oil
  • 1/2 cup sugar
  • 1 tsp vanilla extract
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 1/2 cups all-purpose flour
  • 1/2 cup chopped nuts or chocolate chips (optional)


  1. Preheat your oven to 350°F (180°C) and grease a 9×5-inch loaf pan.
  2. In a large bowl, whisk together the sourdough starter, mashed bananas, eggs, melted butter or oil, sugar, and vanilla extract until well combined.
  3. Add the baking soda, salt, and flour to the bowl and stir until just combined. If desired, stir in the nuts or chocolate chips.
  4. Pour the batter into the prepared loaf pan and smooth the top.
  5. Bake the banana bread for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
  6. Remove the bread from the oven and let it cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.

This recipe yields a flavorful and moist banana bread with a slightly tangy and sour flavor from the sourdough starter. The texture is tender and slightly dense, with a slightly crusty top. If you’d like a lighter, fluffier texture, you can try using a mixture of all-purpose flour and whole wheat flour or adding some baking powder to the recipe. Enjoy!
