For our reception we're having individual cakes as centerpiece cakes. We chose to do this because we have two couples that are vegan and one that has celiac and cannot have gluten. We are seating them all at the same table so that they can have a cake for their dietary needs.I'm having a baker make the other cakes and I will be making the cake for this table because I just don't trust that it won't get cross-contaminated, etc. I saw a post on here to use Pamela's cake mix for the GF, but what icing? Are there restrictions on the icing? I need a vegan buttercream so that it looks like the other cakes. Does anyone have any recipes? Ideas...HELP!
