Buttercream Frosting

Cael wanted white frosting for his birthday cupcakes and a friend recommended this buttercream recipe. It turned out perfectly. I made it a day ahead of time and refrigerated it overnight. After coming up to room temperature it spread perfectly. I did double the recipe and it was the perfect amount for 36 cupcakes.  http://m.allrecipes.com/recipe/174347/quick-and-almost-professional-buttercream-icing
