  • Grease and flour two 8” x 8” baking pans with extra butter and flour. Preheat oven to 350 degrees Fahrenheit.
  • In the bowl of a stand-up mixer, beat sugar, butter, and brown sugar together until light in color, about 3 minutes. Add eggs and vanilla and beat to combine. Add flour, baking soda, and salt and mix on low speed until just combined.
  • Add bananas, sour cream, and chocolate chips and mix until just combined. Divide batter between pans and spread evenly. Bake for 35-40 minutes, or until a tester inserted in the center comes out clean. Set aside to cool completely before removing from the pan.
  • In the bowl of a stand-up mixer, combine peanut butter, powdered sugar, butter, and vanilla to make a frosting. Beat on medium-high speed until light and fluffy, about 2-3 minutes.
