I'm making a 3-tiered Fantasia cake and want to make the top tier Mickey Mouses' wizard hat from the mop and water segment of the show. I have not a clue how to start to sculpt this hat. I make a lot of tiered cakes but usually do my sculpting with modeling chocolate or gum paste. I have never done a sculpted cake of any kind! I think this tier will take about 4 6" round cakes that I'll stack and shape. Do I fill the cake between the layers before I cut or do I cut first for a dry fit and fill after? Do I mark the center of the top cake and cut down from there? It'll be covered in marshmallow fondant in the end.
Any help would be much appreciated! :)
