Can you freeze a cake with whipped cream as frosting?

Freezing a cake frosted with whipped cream is generally not recommended, as the whipped cream will deflate and lose its structure upon thawing, resulting in a compromised texture and appearance. Whipped cream is best suited for serving fresh and quickly as it doesn't hold up well to freezing and thawing.

If you're looking to prepare a cake in advance, consider using frostings that freeze well, such as buttercream, ganache, cream cheese frosting, or frozen whipped cream (also called "mock whipped cream"), which is stabilized with gelatin or cornstarch. These frostings can be made ahead of time and frozen alongside the cake, ensuring a consistent texture and enjoyable eating experience when ready to serve.
