Ingredients

  • 2 cups (250g) all-purpose flour
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • ½ cup (1 stick or 113g) butter, room temperature
  • ½ cup (100g) brown sugar
  • ½ cup (100g) granulated sugar
  • 2 large eggs, room temperature
  • 1 tablespoon vanilla
  • 4 ripe bananas, chopped or mashed
  • 1 cup sourdough starter

Instructions

  • Preheat oven to 350°F. Prepare a 9x5-inch loaf pan with non-stick spray.
  • In a medium bowl combine the flour, baking soda, and salt. Stir with a fork to combine ingredients. Set aside.
  • In a large bowl (or bowl of your stand mixer) add the butter and sugars. Mix on medium-high with a hand-held mixer until ingredients are fully incorporated, about 1-2 minutes.
  • To the bowl add in the eggs, vanilla, and bananas. Mix very well until only a few lumps of banana remain. May need to scrape the bowl.
  • Add in the flour mixture and the sourdough starter and stir gently by hand.
  • Pour batter into prepared pan.
  • Bake at 350°F for 55-65 minutes or until an inserted toothpick is removed with crumbs but no wet batter. Do not overbake.
  • Allow to cool for at least 10 minutes before cutting.
