I put a crumb coat on and put it in the freezer for a while. Then I put a regular layer of frosting on it and put it back in the freezer. Now, how long after I take it out of the freezer do I have to wait before I cover it with fondant? I really do not want to mess this up!!! Thanks in advance!!!

I usually don't wait, just get right to it. Of course, don't put it back in the fridge or freezer after covering w/fondant (please don't be insulted, not sure if it's your first fondant cake or not.)

Hope this helps!

I personally dont like to cover cakes that are really cold or frozen. It just didn't very well for me. Sometimes I will chill them for a bit though. I know others have had good luck with it however.

From what I have read and seen on CC, they say you should put your fondant on to your crumb base, as this acts as a glue for the fondant
to stick to the cake.
I personally would not put it into the freezer to chill, the fondant won't
stick to it then.

I was recently pressed for time and hesitantly covered a cake with fondant that was still partially frozen in the center. The outside was thawed, so I think that is what made the difference. I didn't have a problem with condensation, the outside wasn't cold to the touch. I'm not sure how smooth your BC layer is, but it will be easier to smooth it out under the fondant if it isn't frozen hard. Hope this helps.

I don't freeze either I do put it in the fridge for a while so the icing is not shifting under the fondant while I smooth it.
