Ingredients

13 servings
  • 1 1/2 cups ripe bananas (mashed, about 13 oz or 3 1/2 to 4 medium bananas)
  • ¼ cup sourdough discard
  • 1 ⅛ cups unbleached all-purpose flour (6.75 ounces; 1 cup + 2 tbsp)
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder (for better rise)
  • ¼ teaspoon salt
  • 2 tablespoons unsalted butter (1 oz, softened to room temperature)
  • ½ cup packed light brown sugar ( or monk fruit brown sugar)
  • 1 large egg
  • 1 large egg white (for more structure)
  • 1 teaspoon vanilla extract
  • Baking spray
  • Parchment paper

Steps

  1. Preheat oven to 350°F. Spray a metal loaf pan with baking spray and line it with parchment paper, leaving some overhang on the long sides for easy removal.

  2. Mash the bananas in a medium bowl until mostly smooth with some chunks. Stir in the sourdough discard.

  3. In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.

  4. In a large bowl, beat the butter and brown sugar until light and fluffy, about 1–2 minutes. Add the egg, egg white, and vanilla; mix until smooth. Stir in the banana mixture.

  5. Gradually fold in the dry ingredients with a spatula until just combined—do not overmix.

  6. Pour the batter into the prepared loaf pan and smooth the top. Bake for 40 to 45 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.

  7. Lift the loaf out using the parchment overhang and transfer to a wire rack to cool completely.
