A moist and flavorful banana bread made with sourdough discard and crunchy toasted walnuts, perfect for cozy mornings or snacks.

Ingredients

Scale
  • 3 medium ripe bananas, mashed
  • ½ cup (120g) sourdough discard, unfed
  • 2 cups (240g) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon baking powder
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • ½ cup (113g) unsalted butter, melted and cooled
  • ¾ cup (150g) packed brown sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • ¾ cup (about 90g) chopped walnuts, toasted

Instructions

  1. Preheat the oven to 350°F (175°C). Grease a 9×5-inch loaf pan with butter or non-stick spray, then lightly dust with flour or line with parchment paper.
  2. In a medium bowl, mash the ripe bananas with a fork or potato masher until mostly smooth with a few small lumps remaining.
  3. Add the sourdough discard to the mashed bananas. Whisk in the melted and cooled butter, brown sugar, eggs, and vanilla extract until combined.
  4. In a separate large bowl, sift together the flour, baking soda, baking powder, salt, and ground cinnamon.
  5. Pour the wet banana mixture into the dry ingredients. Gently fold together with a spatula or wooden spoon until just combined; a few streaks of flour are okay.
  6. Fold in the toasted chopped walnuts evenly.
  7. Pour the batter into the prepared loaf pan and smooth the top with a spatula.
  8. Bake for 55-65 minutes, starting to check at 50 minutes by inserting a toothpick into the center; it should come out clean or with a few moist crumbs. Tent with foil if the top browns too quickly.
  9. Remove from oven and let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

If sourdough discard is very liquidy, drain slightly or use less to avoid runny batter. Toast walnuts in a dry pan for 3-5 minutes for enhanced flavor. Avoid overmixing to keep bread tender. Use ripe bananas with brown spots for best sweetness. For dairy-free, substitute butter with coconut or neutral oil. Gluten-free flour blend can be used but texture may vary.
