When you're making a character cake with one of these tins, do you add any jam / buttercream / both filling?
I'm making a batman one today and the cake itself isn't a particularly deep one and I'm worried that dividing it to make it into a sandwich could damage it.
I'm going to put butter cream on it, then a sugarpaste covering and do detail in more butter cream, but I think a bit of jam makes it that much more moist and gives more flavour.
What to do?
