  • 1 teaspoon salt
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/3 cup coconut oil, melted

Instructions

  1. Preheat oven to 350˚F and grease a 9-by-5-inch loaf pan lightly with cooking oil spray. 
  2. In a medium bowl, sift the flour together with the salt, baking powder, and baking soda. Set aside.
  3. Add the coconut oil and coconut sugar to the bowl of a stand mixer fitted with the paddle attachment. Beat on medium speed until combined. Add egg and mix until incorporated. 
  4. Add mashed bananas and sourdough starter, and stir on low speed until just combined. Stir in vanilla extract
  5. Add flour mixture and the chopped walnuts to the wet ingredients. Stir just until blended. 
  6. Pour into the prepared loaf pan. 
  7. Place the flour, sugar, and salt for the topping in a small bowl, and stir to combine. Cut in butter with a pastry cutter or two knives, until mixture resembles coarse crumbs. 
  8. Scatter the mixture on top of the batter in the pan. 
  9. Bake for 1 hour, or until a toothpick inserted in the center comes out clean. Cool in the pan for 20 minutes before removing and transferring to a wire rack to cool completely. Slice and serve.
