  • 1 Cup Flour

  • ½ teaspoon Baking Soda
  • 3 Very Ripe Bananas
  • ¼ Cup Honey
  • 1 Egg
  • 1 teaspoon Vanilla Extract
  • 1 Cup Old Fashioned Rolled Oats

  • Preheat the oven to 375 degrees and 
  • Grease a 12 muffin pan and set aside.
  • In a large bowl mix together the flour, sourdough starter, salt, baking power and baking soda and set aside.
  • In a medium sized bowl mash the bananas with a fork. Then add in the egg, honey, vanilla extract and combine with a hand mixer. 
  • Add the wet ingredients into the dry ingredients.
  • Fold in the oats and chocolate chips.
  • Fill each muffin about ¾ full and bake on the center rack for 18-20 min until a toothpick inserted comes out clean.

1. Make sure your bananas are very ripe. It makes it a lot easier to mash.
2. Use a recently feed starter that has had time to rise
3. Substitute the chocolate chips for chopped walnuts for a healthier version.
4. I used smaller bananas with this recipe if you have larger ones just use two
