- Lay the plastic wrap flat on your counter and place the cake in the center of the plastic wrap.
- Carefully secure the plastic wrap completely around your cake.

- To flash freeze, simply place your cake on a cookie sheet and place it in the freezer for an hour or so. Once the icing or other toppings are relatively hard you can remove it and get started wrapping it.
- Go ahead and wrap your cake completely with two separate layers of plastic wrap to maintain maximum freshness and moisture.
- If you would like to add an additional layer of protection, you can then add a layer of aluminum foil around the cake.
- Place your wrapped cake into a freezer bag or large air tight container. If you're using a freezer bag, ensure that you have squeezed any extra air out of the bag.
- Label your bag or container with the date and then place it into the freezer and a spot where your cake will not get smashed.
How to Defrost Sponge Cake
The best way to defrost sponge cake is in the refrigerator. Though this does take longer than doing it on the counter or other methods, it is important to go slow with the defrosting so that the light texture of the cake doesn't suffer in the process.
To defrost the sponge cake, remove it from the freezer and place it into the fridge. You can leave it in the packaging. The only exception is if there is any moisture build up or obvious freezer burn in the package, you may want to put it in a new container to defrost so it doesn't become soggy.
Depending on the size of the slices or if you froze an entire cake, the defrost time can vary. But, for reference, individual servings/slices easily fully thaw overnight in 8 - 10 hours.
Once it is defrosted, it is almost exactly the same as fresh except the light, airy texture is slightly more compact.
