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.
For a shortcut, remember that a 9-inch round cake pan holds about 6 cups (if the batter is 1 1/2 inches deep). A 13-by-9-inch pan holds 12 cups. And a standard cupcake pan, with 1/2 cup batter in each of six cups, holds 3 cups. So a two-layer cake batter should convert easily to 12 cupcakes or a sheet cake.
