Do you sell this cake? No, just for fun Share a little about the materials, processes, and techniques used to create this cake My Granddaughter had her heart set on a Barbie doll cake, and only doing it as a hobby. I was a bit worried about it, but once I bought the Barbie, I set to work. looked up how to do the ruffled frill for the skirt and looked at a few pictures if other cakes and I got started. Had some trouble with the ruffles at first, but after a couple of goes I got the hang of doing them, keeping in mind to keep the gum paste and fondant moist in a bag. I soon had Barbie all dressed up and ready to go to the party!! Must admit I got carried away with the decorating, but My Granddaughter loved it..
