  • Preheat oven to 350° and grease a 8x8 baking dish or line with parchment paper.
  • In a large mixing bowl, whisk together the bananas, butter and sugar.
  • Add in egg and vanilla and whisk until well mixed.
  • Stir in flour and cocoa with a wooden spoon or rubber spatula until well incorporated.
  • Evenly spread the brownie batter into the prepared baking dish.
  • Drop the peanut butter by tablespoons on the brownie batter.
  • Using a butter knife or chop stick, swirl the peanut butter into the brownie batter.
  • Bake for 25-35 minutes.



If you like a more fudgey and gooey brownie bake around the 25-30 minute mark. If you like a more cake like brownie, bake around the 30-35 minute mark. I bake mine for 32 minutes and they turn out just a touch gooey and perfect!
