Delia's all in one cake how many days b4 birthday can I cook it?

[Noellefielding]

For dd's bday I'd like to cook it a few days before but not sure the optimum time. party on sunday, I'd like to cook it Friday ideally or even thursday...

Yep cakes are ok as look as kept airtight, Thurs would be ok as long as a moist cake. The cakes in the supermarket must be kept for ages on the shelves!

thanks!

Sponge cakes freeze beautifully, so you could make it a week or two in advance and freeze it.

Agree with bunbaker - infact I always freeze and then ice when still frozen, much firmer and fewer crumbs get in the icing.
