Can I freeze leftover cake frosted with Rich & Creamy or Whipped frosting?
A. You sure can! Before freezing, you want the frosting to be nice and firm. So let it dry before covering, or put the cake–uncovered–in the freezer until the frosting firms up. Cover the cake with plastic wrap or foil. (To keep the wrap or foil from touching the frosting, make a “tent” by sticking a few toothpicks into the top of the cake.) Freeze the cake for up to 1 month. To thaw it, loosen the cover and let it stand in the fridge overnight.
