How thawed does a cake need to be before frosting it?

It is usually best for it to be completely thawed. If you ice it too soon, the icing has a tendancy to bubble away from the cake as it thaws.

I like to frost mine while they are frozen. If they didnt get any wrinkles or dents while freezing, If they did i let them thaw completly and they usually regain their shape. I sopose the bubbling up thing may have to do with what type of frosting you use. HTH

Okay so ice while frozen. How long does it take the cake to not be frozen any more?
