Bake the extra batter and freeze the cake... Frozen cakes are the best

Cake batter can be frozen.

It's easiest to freeze in the cake pan you'll use for baking (if you have enough pans). Or you can just bake the extra batter into a cake layer, and freeze that.

Whatever works best for you; it's all good.
