To prepare a Sybil Carters chocolate peanut butter frosting desserts recipe, first you need to prepare the ingredients. First, you will need the following ingredients: 1 cup confectioners' sugar 1 tablespoon vanilla extract 2 tablespoons milk Instructions: Preheat the oven to 350 degrees F. Grease and flour two 8-inch round cake pans. In the bowl of an electric mixer, cream together the butter and sugar until light and fluffy. Add the vanilla and the egg and beat until smooth. Gradually add the flour mixture, beating well after each addition. Scrape down the sides of the mixing bowl as you continue to beat the mixture until it's just combined and no streaks of flour remain. Pour the batter into the greased pan and bake the cake for 20 to 25 minutes or until the toothpick inserted in the center comes out clean. Let cool before frosting.
