Just an aside here....my sister went to The Magnolia Bakery in NYC. She said they have the BEST frosting. Apparently they have like 8-10 Kitchen Aid mixers going at all times full of buttercream frosting. They told her the secret was beating it for like 20 minutes.
She made some for cupcakes over Christmas and I must say, it was the BEST and fluffiest frosting!
So...REALLY beat your ingredients!
