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.
