Print Recipe


  • ½ cup butter melted
  • 1 cup sugar
  • 2 eggs
  • 3 bananas mashed
  • ¾ cup buttermilk
  • 2 teaspoons vanilla
  • 2 cups flour
  • 2 teaspoons baking powder
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 1 ½ cups mini chocolate chips divided


  • Preheat the oven to 350F.
  • Grease a 9x13 baking pan. Set aside.
  • In a large bowl, with a whisk or electric mixer, beat together the butter, sugar and eggs.
  • Add the banana, buttermilk and vanilla and mix well.
  • Stir in the flour, baking powder, baking soda and salt.
  • Fold in 1 ¼ cups of the chocolate chips.
  • Pour the batter into the prepared pan.
  • Sprinkle the remaining chocolate chips over the top.
  • Bake for 30 minutes, until a toothpick comes out clean.
  • Allow to cool completely in the pan before cutting into squares.



  • The more ripe your bananas are the sweeter and more banana flavored these bars will be. 
  • If you don’t have buttermilk on hand you can add a tablespoon of lemon juice to ¾ cup of milk. The acid in the lemon juice ferments the milk and acts as a raising agent.
  • Don't over mix the batter, the dry ingredients should be just combined.
  • Let the cake cool completely before cutting into bars.
