I am making and a cake ad I have to finish baking and crumb coating in 2 hours. I want have time to leave the cake to dry before I have to freeze it so I was wondering:

-Can I freeze a cake that has been crumb coated so I can use it in a week?
-Can a cover a cake in cling film and foil to put in the freezer straight after crumb coating?

The short answer is Yes!

Yes, absolutely, that's what I always do when carving. Thaw with all the wrapping on, though, so the codensation forms on the wrapper and not on your icing.

I was also wondering if you have to leave it before an hour before wrapping and freezing.
