Sheet cakes are a very unique type of cake that isn’t usually used for beautiful cakes. Sheet cakes are most often used at kids’ birthday parties or when you don’t want to spend hours making some type of elaborate cake.
So, an average box of cake mix weighs around 15-16 ounces. Once you add your eggs, water (or milk), and oil, the weight of the batter will be around 2 pounds.
For half-sized sheet cakes, we recommend using between 2 and 3 boxes of cake mix. Again, this is to ensure you have enough cake batter to make a thick layer of cake. And, if you have a bigger pan, you are guaranteed to have enough batter.
The final answer will largely depend on the type of buttercream you have made and even how fluffy it is. You can have a single recipe that only makes 2 cups of frosting, but when using a proper mixing technique can also make 5 cups!
