So far, the people who have bought the giant cupcake said they aren't burning them. Just for looks and a novelty. I have burned my regular size cupcake and the sprinkles just melted with the frosting. Once I get past the rush of the holidays, I'll try the suggestions you all gave me to adhere the top and bottle of this two-piece silicone mold. If I get one to work, I'll post a picture.
