I am making a 3D dinosaur cake this weekend and have decided to do the dinosaur in pieced together/sculpted cake covered with fondant. That dinosaur will then go on a flat rectangular cake that will be frosted. I am concerned that once I have the dinosaur covered in fondant and ready to transfer it might fall apart when I go to put it on the cake, since the head and tail will be pieces held together with frosting. Normally I would freeze it first, but with the fondant I can't, and don't want to put the fondant on while it is on the cake.
Any tips? I haven't done a 3D cake that wasn't decorated and put together on the cake and am not a fondant expert, either.
I always chill my fondant cakes before stacking...makes it easier, and it won't hurt the fondant in the least.
I'd place them on the cake in sections...body first...head....tail. Would be easier once your fondant has been allowed to dry out and firm up
perhaps you can cut a cardboard board to shape and build it in that , It should make it easier to transfer.
