Absolutely, you can. A frozen cake can maintain its freshness when properly wrapped and stored.
Okay, so how do I properly freeze the cake?
First, cool the cake completely if it's still warm. Then, wrap it tightly in a plastic wrap, followed by a layer of aluminium foil. You can also put it in a freezer-safe container or bag to add extra protection.
That's helpful. And how do I defrost it before serving?
When ready to eat, take the cake out of the freezer and let it thaw at room temperature. Depending on the size, it may take a few hours. Remove any plastic or foil wrapping once it's reached room temperature.
