Bake and cool cake according to recipe directions. Decide if you will be freezing the cake layers or slices of assembled cake.
To freeze cake layers, wrap each layer of cake individually in Press & Seal plastic wrap. Slice layers of cake into an airtight Ziploc freezer bag. You can also use foil to wrap your plastic wrap layers. Be sure to label your freezer bags.
To freeze slices of cake, wrap individual slices (with frosting) in Press & Seal wrap. Slide slices into ziploc bag. Label and freeze.
Cake layers and slices can be frozen for up to 3 months. Thaw in refrigerator overnight.
