Ingredients

The following ingredients have 4 Servings
  • 2/3 cup white granulated sugar
  • 1/2 cup sour cream
  • 1 egg
  • 2 Tablespoons butter, softened
  • 2 medium bananas, mashed
  • 1 teaspoon vanilla extract
  • 1 cup all purpose flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 2 Tablespoons butter, softened
  • 1 1/4 cups powdered sugar
  • 2-3 Tablespoons milk
  • 1/2 teaspoon vanilla extract

Instruction

  • Preheat oven to 350 degrees. Spray an 8x8 baking pan with cooking spray and set aside.
  • Using an electric mixer, beat together the sugar, sour cream, egg, and softened butter over medium speed until combined. Add in the mashed bananas and vanilla extract. 
  • Stir in the flour, baking soda, and salt by hand, mixing until just combined. Pour into the prepared baking dish and bake in the preheated oven for 22-28 minutes, until top is golden brown and a toothpick inserted in the center comes out clean.
  • Cool completely on a wire rack.
  • To make the frosting, beat the butter, powdered sugar, milk, and vanilla extract with an electric mixer until smooth. Evenly spread over the cooled cake and serve. I like to sprinkle the frosted cake with a little cinnamon for an extra boost of flavor and color, but this is optional! Refrigerate any leftovers.
