In general, the 13-by-9-inch cake will take about 5 to 10 minutes less than the 9-inch layers. To be safe, start checking about 15 minutes before the time in the original recipe. Cupcakes usually take about half as long as a 9-inch round cake. If the cake called for 30 to 35 minutes of baking time, start checking the cupcakes after 15 minutes.
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.
