How can I store my funfetti cake?
Ideally, you should use a cake storage container like this one. The cake will keep for about 5 days at room temperature in this container. If you do not have a cake storage container then you can cover the top with plastic wrap and foil (be careful not to stick it to the frosting or it will pull off when you remove the plastic). The cake will only keep for about 3 days at room temperature using this method.
