I'm making a cake for my nephew's birthday and I got it all assembled. 3 layers, Italian meringue buttercream, and I froze the entire cake completely wrapped in Saran wrap blah blah blah. Anyways, for some stupid reason I decided to cover it in fondant while it was still frozen. This was a huge huge mistake. I don't know why I did it but I did. Is there any way to salvage this? The fondant is on but it is real sticky. I can't really do much with it at this point. And it still isn't even fully defrosted yet so I don't know what to do. It took me a long time to make the layers. Cuz I did 2 different kinds of cake. Is there any way to salvage this? Should I just take the fondant off?? Or is it ruined?
