It takes two 18-ounce boxes of cake mix to make a half sheet cake, measuring approximately 12-by-18 inches. A half sheet cake provides 36 to 108 servings, depending on how it is sliced. Commercially prepared half sheet cakes are often made by assembling two 9-by-13-inch cakes on a cake board.
Most bakers think of orders in terms of full, half, and quarter sheet cake pans, which can actually mean a handful of different sizes. As a result, it`s best to discuss the number of servings and the size of each serving instead. From there, you can determine which size pan will work best for the application.
