i wrap with saran wrap after letting them cool . and then with heavy foil.you can freeze cakes more than a month. lots of decorators will say the same. i just sat out for a little bit . 30 min- an hr. then torte , etc. hth
I double wrap in press and seal. Then take it out of the freezer, fill, crumbcoat and then let it come to room temp for about 2 hours and then cover with fondant. If using buttercream as the final coating then you don't have to wait the two hours.
