This week-end, I'm making a spongebob cake for my sons 4th birthday. I'm planning on sculpting spongebob's pineapple house from cake, having a layer of frosting, then covering with fondant. I've just made the pineapple leaves from a 50/50 gumpaste fondant mix, and left them to dry. Can I stick them straight into the cake? Or will they absorb moisture and wilt? If so, what are my options? Thanks in advance for your help.
It depends on h0ow thick you made them and how moist the cake is
I suggest you attach toothipcks by 'taping' them w/a bit on fondant (or gp) if you cannot stick them into the bottom of the leaf now.
gumpaste will soften and go limp/break
