I made this one for my granddaughter's birthday. It is covered with BC frosting and decorated with fondant. I had started off with the doll cake, but my doll got destroyed the night before the birthday and I had to come up with a quick replacement, so I made an easy dress top.
I'll bet your granddaughter wanted a dress like this for herself after she saw it! Nice job.
Did you upload the photo of the doll? I think, if its the one I just looked at, it was beautiful. Sorry to hear it got destroyed! The cake is beautiful too!
