Ingredients

  • For the Banana Cake:
  • 1/4 cup Unsalted butter, room temperature
  • 3/4 cup Granulated sugar
  • 2 large Egg yolks
  • 2 large Egg whites
  • 2/3 cup Mashed bananas (about 2 small bananas)
  • 1/4 cup Sour cream
  • 1 cup All-purpose flour
  • 1/2 tsp Baking soda
  • 1/4 tsp Kosher salt
  • 1/2 tsp Vanilla extract
  • 1/4 tsp Ground nutmeg
  • For the Salted Peanut Butter Frosting:
  • 3/4 cup Creamy peanut butter
  • 2 tbsp Unsalted butter, room temperature
  • 1/2 tsp Vanilla extract
  • 1/2 tsp Kosher salt
  • 3/4 cup Powdered sugar

Instructions 

  • Preheat the oven to 350 degrees. Spray an 8X8-inch cake pan with nonstick cooking spray or line with parchment paper
  • In a mixer fitted with the paddle attachment, cream the butter and sugar. Next, add the egg yolks in one at a time until combined. Add in the mashed bananas, sour cream, and vanilla extract. Continue to mix until combined.
  • In a large bowl combine the dry ingredients (flour, baking soda, and salt). Take the flour mixture and in thirds, add it to the butter mixture until well combined. In a separate bowl add the egg whites. Using an electric mixer whip the egg whites on low speed until stiff peaks form about 3 to 4 minutes. 
  • Take the egg whites and gently fold them into the cake batter. Pour the batter into the prepared pan and bake for about 20 minutes or until a toothpick inserted in the center comes out clean. Let cool slightly before serving for best results. 
  • While the cake is cooling, prepare the frosting. In a stand mixer fitted with a paddle attachment, beat the unsalted butter and peanut butter until creamy. Add in the vanilla extract, kosher salt, and powdered sugar. Keep mixing until well combined and creamy.
  • Once the cake has cooled, frost it with the salted peanut butter frosting and enjoy!
