I had two cakes in the fridge and the door to the fridge got left open. The fridge got really wet inside and dripped condensation all over the cakes. They were covered in mmf and seem pretty salvageable but I am worried about the cake inside....will it be mushy?? This is not a cake I am getting paid for. Its for a family event but I dont want a mushy cake.....what do I do? I thought about making a back up cake...has this ever happened to anyone else??

I don't know what you mean by wet. But I think that a little condensation wouldn't hurt the cake inside. Fondant in my opinion is a very good stablizer and protector.

How long was the door open? The crumb coat and fondant will protect the cake so the inside should be fine, and the fondant should dry also and be ok.
