Variations Ideas:

  • Chopped Nuts – If you love nuts in your brownies, add them in the banana bread batter. Chopped pecans or chopped walnuts are always a great addition to this sweet treat.
  • Chocolate Chips – Chocolate and banana bread is a great combination and delicious added to these brownies. You can add in mini or regular chocolate chips. Peanut butter chocolate chips would also be a delicious combination.
  • Frosting – The brown sugar frosting is my favorite. But feel free to change the frosting to a cream cheese frosting. You can also use a store bought frosting if you prefer.
  • Greek Yogurt – Substitute the sour cream with a plain Greek yogurt. This will make these brownies a lighter and a healthier version.

Recipe Tips:

  • Bananas – The best time to make this recipe is when your bananas are really ripe. The riper the bananas the better these brownie tastes.
  • Prepare Baking Dish – Make sure to prepare the baking dish by spraying with cooking spray. This helps for cleanup and serving the brownies.
  • Combining Ingredients – When combining the ingredients for the banana bread brownies, make sure to not over mix. In large bowl beat until everything is combined.
  • Frosting – For the best texture, we recommend pouring the glaze over the brownies that are warm. I love to serve these brownies when they are slightly warm. There is no need to cool completely before adding the frosting.
  • Baking Brownies – While baking the brownies watch carefully. You want to bake the brownies until they are golden brown. Use a toothpick to check the center of the cake. If comes out clean, then brownies are done.

    Delicious recipe!! My husband is not a fan of chocolatey desserts and he loves this one. I add chopped pecans to the top and pour the frosting on top. I also thought about adding chocolate chips inside the batter prior to baking. Definitely would recommend this recipe to anyone that has too many ripe bananas!
