I am going to make the cake for my daughter's baby shower. I am going to make a 3D sugar fondant elephant and circles to sit on top. Would I need a particular type of cake to support his weight? I would appreciate any suggestions or recipes.
No, you can use any type of cake. If he is that heavy, just put some type of support in there. Sometimes I'll put a straw under a topper. Or, when I've had bigger toppers, I've put 3 straws in a triangle and put a 4" cake board over them to put the topper on.
If it's just a little 2-3" elephant made out of fondant, you shouldn't need anything. I do those all the time with every type of cake.
