Recipe Expert Tips
You may have noticed that this recipe does not have any milk added like most butter cream frosting recipes do.I left the milk out because when I was getting ready to add it I really liked the thick consistency of the frosting. I did not want to loosen it up. If as you are trying this recipe you think it is too thick go ahead and add 1 or 2 tbs of milk. Add one at a time that way if after the first one you like the way it looks you can leave it be.
