Ingredients

  • Peanut Butter Cake
  • 1 cup butter, room temperature
  • 1 1/2 cups sugar
  • 1 cup Skippy creamy peanut butter
  • 1 teaspoon vanilla extract
  • 3 eggs
  • 2 1/2 cups all-purpose flour
  • 3 teaspoons baking powder
  • 1 cup sour cream
  • 1 cup milk
  • Marshmallow Frosting
  • 1 1/2 cups unsalted butter, softened
  • 4 cups marshmallow cream (13 ounce jar)
  • 1 tablespoon vanilla extract
  • 1 tablespoon milk
  • 2 cups powdered sugar (or more if needed)
  • 1 cup roasted peanuts, chopped

Method

  • Cake:
  • Preheat oven to 350°F Butter and flour three 9-inch-diameter cake pans. Line the bottoms with parchment paper, then butter and flour the parchment paper. (Or, line cupcake pans with paper liners).
  • In large bowl, cream together butter and sugar with electric mixer. Add peanut butter and vanilla and cream well. Add eggs one at a time, mixing well after each.
  • In separate bowl, whisk together dry ingredients.
  • Add dry ingredients to peanut butter mixture alternately with sour cream and milk. Mix on low speed just until blended.
  • Pour cake batter into prepared pans (approximately 2 cups per pan), spreading evenly in pans. (Or, fill cupcake cups 2/3 full).
  • Bake for 15-20 minutes or until tester inserted into center of cake comes out clean. Do not over bake. Remove from oven and cool cakes in pans on rack 10 minutes.
  • Run small sharp knife around pan sides to loosen cakes. Turn cakes out onto racks and cool completely.
  • Frosting:
  • In large mixing bowl, beat butter until creamy. Add marshmallow creme, milk and vanilla extract and mix well. Slowly add powdered sugar a little at a time, mixing well after each addition. Add additional powdered sugar, if needed, to reach desired consistency.
  • Frost cake or cupcakes. Sprinkle with chopped peanuts.
