I have a Nemo cake to do and my FBCT seem to not turn out right. Can I make the characters out of royal and set them on a cake iced with b/c? Or will the b/c break down and ruin the royal?
I made a cake (the Egyptian one in my pics) that had a Royal icing transfer on buttercream. It was served later that afternoon, the same day I placed it on the cake, and had no problems. I would just wait to put it on on the day they will be serving it, not the day before if possible. HTH!
