I don't know really know the name of this cake, so I called it a "frill cake". :)

Does anyone know if there's a tutorial available for this cake? It seems like it would be easy, but would like some pointers. Thanks!

Try googling "fondant wrapped cake"

AThis is very similar to the Maggie Austin frill cake and something I have done several times now. There is a Maggie Austin tutorial on Craftsy. The only difference between this cake and Maggie's would be the number of ruffles and the thickness of them. It's a very easy and forgiving method. Just a bit time intensive.
