can you ice a frozen cake?

[sophy]

Or is it better to wait until it has defrosted?

It's getting buttercream in the middle and galce icing on the top and sides.

Yes, you can ice it while it is frozen.

I wouldn't, the condensation from the defrosting cake will affect the icing. If you're in a hurry to defrost it, seal the cake well in a plastic bag with all the air sucked out (so the plastic is touching thecake) and immerse it in a big bowl of cold water.

Hmmm opinion is divided, anyone else?

No direct experience but i wouldn't, for the reason mablepurple says.

...but maybe losingitagain has actually done it?
