Ingredients

  • 3 medium very ripe bananas (about 1 cup mashed)
  • 1 cup active sourdough starter or discard
  • 2 large eggs
  • 1/2 cup melted coconut oil (or butter/vegetable oil)
  • 3/4 cup coconut sugar or light brown sugar
  • 1 teaspoon vanilla extract
  • 1 1/2 cups whole wheat or all-purpose flour
  • 3/4 teaspoon sea salt
  • 1 teaspoon baking soda
  • 1/2 teaspoon cinnamon (optional, but highly recommended)
  • 1/2 cup chopped walnuts or pecans (optional)

Instructions

  1. Preheat your oven to 350°F (175°C) and grease or line a 9×5-inch loaf pan. Because stuck banana bread is a heartbreak nobody needs.
  2. In a large mixing bowl, mash the bananas until mostly smooth. A few lumps are charming, like dimples, IMO.
  3. Add the sourdough starter, eggs, melted oil, sugar, and vanilla. Stir until everything is blissfully united.
  4. In a separate bowl, whisk together flour, salt, baking soda, and cinnamon. Gradually add dry ingredients to wet, stirring just until combined. Don’t overmix tenderness depends on it.
  5. If you’re feeling fancy, fold in chopped nuts. Pour batter into prepared pan and smooth the top.
  6. Bake for 45-55 minutes, until a toothpick comes out clean (a crumb or two is okay). If the top browns too fast, tent with foil in the last 15 minutes.
  7. Cool in pan for 10 minutes, then remove to a rack. Try to resist slicing until warm but no longer hot—for the best slices.
