I made three different kinds of cupcakes (yellow, funfetti and devils food) for Palmer's candy themed birthday party and three different types of frosting (vanilla buttercream, strawberry buttercream, and milk chocolate buttercream). We had a cupcake and candy bar at the party, where the kids could frost and decorate their cupcakes with a variety of candy. It was great fun. I've already posted the strawberry and milk chocolate frosting recipe. Here is recipe for the vanilla buttercream frosting. It, like the other frostings, comes from my sister London, queen of cupcakes.
Vanilla Buttercream Frosting
1 cup butter, softened
1 (32 oz.) package powdered sugar
1/2 cup milk
1 tablespoon vanilla extract
Beat butter at medium speed with an electric mixer until creamy; gradually add powdered sugar alternately with milk, beating at low speed until blended after each addition. Stir in vanilla.
