im making a cake today-

im going to take it out and let it cool, once cool i will fill and crumbcoat- but i heard the cake needs to 'rest' can it do this with the BC all over it- and if i leave it out over night to rest will that be ok or will it dry out?

thnk yu all.

Yes, exactly. I crumbcoat the sides and put a plastic cake round on the top with something kind of heavy on top of that (like a tile or book). Let it rest like that overnight. The reason for this is so you don't have any shifting after you ice it. (This will prevent many problems)

The cake won't get dry because the icing 'seals' it in. I tend to think it makes it even more moist because some of the icing kind of soaks into the surface. HTH

The crumb coat will keep the air from drying out and keep the cake moist.

Personnally I bake the cake and leave it with the greaseproof paper on to rest overnight then crumb coat about 10 mins before you put sugarpaste on otherwise your bc will dry out too much for attaching your sugarpaste. Another thing that may have differences in UK and US
