Hi,
New to making and decorating. I'm taking Wilton decorating classes. I have an anniversary cake to make. They requested chocolate cake. Can I do chocolate buttercream filling and crumb coat then white fondant (satin ice) or should I crumb coat w/ white buttercream? Any advice would be appreciated.

As long as you don't roll the fondant super thin, you'll probably be okay. I put white Satin Ice over chocolate without a problem. Actually, if you look at my ladybug cake (with the A on top), it's white Satin Ice over dark chocolate ganache - darker than any chocolate buttercream I've ever seen.

I say go for it (in my very humble opinion)!

Yep, it will be fine. Just "work clean" and make sure to not have any chocolate icing on your hands when you touch the white fondant.

Exactly like they mentioned. I use chocolate ganache under my cakes and my cakes are still white.
