For those who have made the giant cupcake (Wilton or other), what have you used to cover the base? I made a candy melt shell to cover the base, which looked great (nice crips lines, smooth exterior) but was terrible to cut. Has anyone tried using chocolate modelling clay for the base, or marshmallow fondant, or even candy melts with a litlle milk or cream added? I am working on a cake for a friend's surprise party right now, and I would experiment myself, but I have limited supplies and would have to drive several hours to get more supplies (not an option right now). I would appreciate if anyone can share what has worked for them. THANKS SO MUCH!
