I took my cake out of the freezer to carve them. I thought it was defrosted all the way so I filled and crumb coated it. I was getting ready to cover it with fondant when I noticed that it was sweating badly on the top. What should I do? I put it in the fridge (without covering in fondant), but now it seems damp on top. Do I let it sit out overnight or what??? I don't want the fondant to slide off! Thanks for the help!!!

Don't cover with fondant but I'd leave covered in saran until done sweating.

Thanks, ajwonka. Should I keep it in the fridge, then?

I would not keep it in the fridge - the cake needs to come to the same temperature as the room, only then will it stop sweating. HTH
