  • 2 cups All purpose flour*
  • 1 teaspoon Baking powder
  • ½ teaspoon Baking Soda
  • 1 teaspoon Salt
  • cup Vegetable or Canola Oil
  • ¾ cup Sugar
  • 1 tablespoon Egg replacer*
  • 3 tablespoons Water
  • 1 cup Mashed Banana, from 2 medium size very ripe bananas
  • 1 cup Sourdough Starter, unfed
  • 1 teaspoon Vanilla extract
  • ¾ cup Chocolate chips or chopped pecans or walnuts


  • Preheat oven to 350°F. Grease a 9"x5" loaf pan.
  • In a medium size mixing bowl, combine the flour, baking powder, baking soda and salt.
    In a large mixing bowl, combine oil and sugar until sugar is almost dissolved. Add egg replacer, water and mix well. Next add mashed banana and whisk to combine. Add the unfed sourdough starter and vanilla extract. Mix well.
  • Add the dry ingredients to wet ingredients and mix until combined. Stir in the add-ins, chocolate chips or chopped nuts or dry fruit.
  • Pour batter into the prepared baking pan and bake for 50 - 60 mins or until a toothpick inserted into the center of the bread comes out clean.
  • Cool the bread in the pan for 10 minutes, then remove onto the cooling rack and cool completely before slicing. Enjoy with a smear of butter or jam/ Nutella.



  • Feel free to substitute some of the all purpose flour with whole-wheat flour whole-wheat pastry flour.
  • If you are not vegan, then use 6 tablespoons of unsalted butter and 1 large egg. Omit the 3 tablespoons from the recipe.
  • If your sourdough starter is too thick, then stir in some water into the batter to make sure that the bread bakes up light.
  • Add ins can easily be customized to your liking. If you like sourdough banana nut bread, then add a combination of chopped nuts to the batter. Or add chocolate chips, cranberries, raisins and so on.
  • To add flavor to the bread, add ground cinnamon or ground cardamom to the batter.
  • Make sourdough banana bread muffins by pouring the batter into a greased or paper lined muffin pan. Bake at 350°F for 30~35 minutes or at 375°F for 25~30 minutes.
