My son's 3rd birthday is coming up, and being as indecisive as he is, he has chosen 6 of his favorite things. I would like to try to incorporate all 6 on his cake (Little Einsteins, Thomas Train, Mickey Mouse, Dora, Diego, and Elmo). I was thinking of making edible images of the characters with candy clay instead of fondant/gumpaste. Does anyone know if this will work, and if so, how much will they harden? Will they be hard enough to stand vertically on the cake?

Thanks!

what is candy clay? is it sweeter than fondant/gumpaste?

It's a mixture of candy melts and corn syrup. I've never used it before, but it's supposed to roll out like fondant and probably tastes much better.

Yes it hardens. And it's still edible.
