Banana bars with peanut butter frosting

Even though I used to hate bananas, I now constantly have a bunch or two sitting on my counter. I eat them for breakfast, as a snack, frozen in a smoothie, etc. Inevitably, I do get some old ones and they call to me to make them into a banana dessert. There are so many breads and bars featuring bananas you could bake for weeks with the recipes out there.


These bars made me feel like they were banana bread – it wasn’t very cake-like, but with frosting so you really have a win-win situation here. Add chocolate chips and it’s a win-win-win!


Banana bars with peanut butter frosting, adapted from BHG


  • 1/2 cup butter, softened
  • 1 cup sugar
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 teaspoon cinnamon
  • 1 egg
  • 1 cup mashed bananas (about 3 medium)
  • 1/2 cup dairy sour cream
  • 1 teaspoon vanilla
  • 2 cups all-purpose flour
  • 1 cup mini chocolate chips


  1. Preheat oven to 350 degrees F. Grease a 15x10x1-inch baking pan; set aside.
  2. In a large bowl, beat butter with an electric mixer on medium to high speed for 30 seconds. Add sugar, baking powder, baking soda, cinnamon and salt. Beat until combined, scraping sides of bowl occasionally. Beat in egg, mashed bananas, sour cream, and vanilla until combined. Add the flour gradually and mix until incorporated. Finally, stir in the chocolate chips.
  3. Pour the batter into the prepared pan, spreading evenly. Bake in a 350 degree oven about 25 minutes or till a wooden toothpick inserted near the center comes out clean. Cool in pan on a wire rack.
  4. Spread with frosting when cooled. Cut into bars.

Frosting Ingredients

  • 3 tablespoons butter, softened
  • 3 cups powdered sugar
  • 1/2 teaspoon cinnamon
  • 2 tablespoons PB
  • 1 teaspoon vanilla
  • Milk: 3ish tablespoons
  • 1 cup mini chocolate chips


  1. In a medium mixing bowl beat butter and peanut butter on medium speed of an electric mixer for 30 seconds. Gradually beat in half of the powdered sugar and all of the cinnamon. Beat in 1 tablespoon of milk and vanilla. Beat in the rest of the powdered sugar and enough milk to make a frosting of spreading consistency. Frost bars and top with the rest of your mini chocolate chips.


Here you can see how thick the mixture is. You will have to spread it onto your jelly roll pan.


And before and after. I had a banana on the edge there and it created that little pocket when it baked up.


Frosting time. At first I thought this wouldn’t be enough frosting. It is, but it is just more of a thin layer of frosting than some other bars I have made.


Topped with chips. You can use your hand to press them into the frosting if you want them to stick a bit more. Alternately, you could also mix them directly into the frosting if you wish. I just like the way this option looks.


I bet this would be good with vanilla yogurt, on ice cream or just alone. These will freeze well and are perfect for sharing. Enjoy!
