Banana Cake:
  • 3 large very ripe bananas
  • 1/4 cup unsalted butter melted
  • 1/4 cup vegetable or canola oil
  • 3/4 cup sugar
  • 1/2 cup brown sugar
  • 3 large eggs
  • 1/2 cup sour cream
  • 1 1/2 tsp vanilla extract
  • 1 tsp baking powder
  • 2 cups all purpose flour OR 1:1 gluten free flour with xanthan gum
  • 1/2 tsp salt
Peanut Butter Frosting:
  • 4 oz cream cheese room temperature
  • 1/4 cup unsalted butter room temperature
  • 1/2 cup creamy peanut butter
  • 1 tsp vanilla extract
  • 1 1/2 cups powdered sugar
Optional Topping:

Method
 

Banana Cake:
  1. Preheat your oven to 350 degrees F. Line an 8-inch pan with parchment paper. Mash all 3 of your bananas in a large bowl; set aside.
  2. In a separate bowl whisk together your butter, oil, granulated sugar, and brown sugar until smooth. Beat in eggs, one at a time.
  3. Whisk in the sour cream and vanilla until smooth. Then whisk in your baking powder and salt.
  4. Fold in flour until no streaks remain. Stir in mashed bananas. Do not overmix.
  5. Pour the batter into prepared pan. Bake 40 to 45 minutes or until a toothpick inserted into the center of your cake comes out almost clean. Allow cake to cool completely before frosting.
Peanut Butter Frosting:
  1. Using an electric mixer, beat your cream cheese, butter, vanilla extract and peanut butter until smooth.
  2. Slowly add in your powdered sugar, continuing to whisk until all powdered sugar is incorporated and your frosting is smooth.
  3. Evenly spread your frosting on to your cake, top with chopped graham crackers if desired. Slice and enjoy!
