I want to make my son some cupcakes to freeze so that when someone has a treat/party he has an alternative I can bring him. He's allergic to pretty much everything that goes in a cake. lol So, my question is, I got a chocolate cake mix that he can have but I need to figure out a dairy free frosting. Any ideas?? I got some tofutti ''cream cheese'' that I thought about making him a cream cheese frosting with, but I haven't found a margarine spread that he can have to add the ''butter'' part of the recipe. Help?
