How long will a large cake stay moist?!
all your big stores, bake the cakes, then freeze them.
when people order them, then they take them out of the freezer and frost them and decorate them fresh.
worked in a large bakery
you should cover it up really good(with plastic or in a plastic type of thing or something) and then leave it outside that'll keep it moist till tuesday:)
hope it goes well for you:)
Make another cake haha JK
