I'm making a three tier superhero birthday cake. On the top layer, the customer would like a Hulk fist coming out of the top. I'm wondering if I should do it in RKT or carve it out of cake. Also, should I cover it in fondant or modeling chocolate? Which would be less heavy? Thanks.
Thanks! Great instructions. How much in advance can I make it? I don't need the cake until February 26.
