Yes! Cake balls can definitely be made ahead of time. They are a very durable dessert as they are all coated in  chocolate, so that cakes stays moist and delicious. I make cake balls at least a day ahead of when I plan to serve them, but you can even make them up to 2 days in advance. Cake balls will stay good in the fridge for up to one week. But, you can also freeze them for up to three months. Just be sure to store them in an airtight container.
