Carrot cake, a rich, moist dessert flavored with grated carrots, cinnamon, nutmeg and walnuts, features a creamy, white topping, often made with cream cheese. You can freeze carrot cake slices in airtight containers for several months. Wrapping carrot cake slices individually allows you to thaw slices one at a time, as needed.
Slice the cake into individual pieces before freezing. Place the frosted cake slices in a freezer-safe glass or plastic storage container. Freeze the cake for two hours uncovered to allow the frosting to harden and set.
Remove the cake from the freezer. Place the cake slices on individual pieces of airtight plastic wrap. Wrap the plastic wrap around each cake slice tightly to prevent moisture from ruining the cake.
Wrap each slice of plastic wrap-covered cake in heavy-duty aluminum foil to create secure outer layers.
Freeze the carrot cake at 0 degrees Fahrenheit for up to three months. To thaw the carrot cake, remove the wrapping materials and place the slices in a plastic or glass container. Allow the cake to thaw in a refrigerator overnight.
Place a piece of masking or freezer tape featuring the storage date on each piece of cake as a handy reference.
