Ingredients

Scale
  • 1 cup (240g) sourdough discard (unfed or fed, room temperature)
  • 3 ripe bananas, mashed
  • 2 large eggs, room temperature
  • ½ cup (100g) granulated sugar
  • ½ cup (115g) unsalted butter, melted and slightly cooled
  • 1 teaspoon pure vanilla extract
  • 1 ½ cups (190g) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • ¼ cup (50g) brown sugar, packed
  • 2 tablespoons all-purpose flour
  • 1 teaspoon ground cinnamon
  • 2 tablespoons unsalted butter, cold and cubed

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, whisk together sourdough discard, mashed bananas, eggs, granulated sugar, melted butter, and vanilla extract until smooth and well combined.
  3. In a separate bowl, sift or whisk together flour, baking soda, salt, and cinnamon.
  4. Gradually fold the dry ingredients into the wet ingredients with a spatula until just combined; do not overmix.
  5. In a small bowl, mix brown sugar, flour, and cinnamon for the topping. Add cold cubed butter and use a pastry cutter or forks to blend until coarse crumbs form.
  6. Pour the batter into the prepared loaf pan and smooth the top gently.
  7. Sprinkle the cinnamon crunch topping evenly over the batter.
  8. Bake for 55-65 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs. Start checking at 50 minutes.
  9. Remove from oven and place on a cooling rack. Cool in the pan for 10 minutes, then remove to cool completely.
  10. Slice and serve, optionally with butter or honey.

Notes

Use room temperature and fairly thick sourdough discard for best results. Keep butter cold for the topping to achieve a flaky texture. Tent with foil if topping browns too quickly. Overmixing the batter can make the bread tough. Ripe bananas improve sweetness and flavor. Store wrapped loosely at room temperature to keep topping crisp.
