Ingredients

  • 5 medium overripe bananas
  • 1/2 cup brown sugar, packed
  • 1/4 cup white miso paste
  • 5 Tbsp. unsalted butter
  • 1 3/4 cup all purpose flour
  • 1 cup sugar
  • 1 tsp. baking soda
  • 1/2 tsp. baking powder
  • 1/2 tsp. salt
  • 2 large eggs
  • 1/3 cup vegetable oil
  • 1/4 cup buttermilk
  • 1 tsp. vanilla extract

Instructions

  • Preheat oven to 350° F.
  • Grease 9×5 inch loaf pan: brush with softened butter and sprinkle an even layer of flour around the pan. Set aside.
  • In a medium skillet add the mashed bananas, butter, brown sugar, and miso. Cook and whisk banana mixture over medium heat until butter melts and mixture begins to simmer. Turn the heat down to low and let simmer for ~3-5 minutes, whisking occasionally.

  • Remove from heat and let slightly cool for about 10 minutes. It does not have to cool all the way, but just so it is not super hot.
  • In a large bowl, combine the eggs, oil, buttermilk and vanilla extract. Add the cooled down banana mixture to this and whisk together.
    2 large eggs, 1/3 cup vegetable oil, 1/4 cup buttermilk, 1 tsp. vanilla extract
  • In a separate mixing bowl, combine the flour, sugar, baking soda, baking powder and salt. Add the dry ingredients to the wet ingredients and gently fold until combined. Do not over mix the batter.
    1 3/4 cup all purpose flour, 1 cup sugar, 1 tsp. baking soda, 1/2 tsp. baking powder, 1/2 tsp. salt
  • Pour this mixture into the prepared pan. Bake for ~45-50 minutes, or until a toothpick inserted comes out clean.
  • Allow bread to cool for 30 minutes before turning out to cool completely.

Notes

  • Bake time can vary. Keep an eye on the bread so it doesn't over bake. 
  • Add 3/4 cup of chocolate chips or walnuts if desired. 
  • Optional but not required: split a banana down the middle vertically then add on top of the batter or just add banana slices on top, side by side prior to baking.
