Can you freeze a  crumb coated cake? And how would you thaw it? In the fridge or counter?

Sure. Wrap it well in several layers of saran wrap & a layer of foil.  I like a slow defrost, so I let it defrost in the fridge & then unwrap it and put it on the counter to come to room temp.  Personally, I like to let it dry then before doing anything else to it.

Sure you can freeze cake at any point.  I prefer to thaw overnight in the frig, then to room temp for a few hours before serving.  Cake tastes best at room temp.  How I wrap it depends on 1) If it's crumb'd 2) or completely iced 3) Or completely decorated 4) how long it will be in the fzr.   If just for a day or up to 1 week I usually only put it into a plastic bag uniced or crumb'd.  If completely iced cover a cookie sheet w/long pieces of plastic wrap in an "+" and place the cake on it - freeze up to 4 hours (ONLY) before removing and wrapping it well with the plastic wrap, then put that into a cake box and the whole thing into a plastic bag.  Wrapped that way it will be good for  3-5 months.  We kept our daughters wedding top tier for over 18 months.  

Thank you, this is very helpful. Between work and raising a family, I don't always have time to do it all in one day.
