If you intend to bake anything requiring frosting this holiday season, might I suggest you try this recipe? I have used this basic recipe for years, as it is easy, quick, and I've never goofed it up. :) Wonderful treats like this have become even more special to me now on the GF diet. I'm having to learn how to modify so many recipes. This one needs no adjustments.
I generally use half of this recipe if I'm just frosting a cake in a pan, or a batch of cupcakes, but if you are doing a full layer cake, or you have children that might sneak off with the bowl, make the full recipe.
2 sticks of butter, room temperature 3 cups of powdered sugar (you could need more if you need the frosting stiffer, so keep it at the ready) 1T vanilla extract pinch of salt (yes...trust me on this one) 2-3T cream
Using stand mixer, cream together butter and sugar for 3-4 minutes. Add vanilla, salt and cream, and continue to mix for another 3-4 minutes. Add more sugar if you need the frosting to be stiffer, 2-3T at a time. If you need the frosting to be thinner, add 1T cream at a time.
