Use recipes designed specifically for a sheet configuration. Sheet cakes are usually thinner than standard cakes so they can be prone to texture and moisture issues. Prepare your pans well with flour, butter, and parchment paper to prevent your sheet cake from sticking.
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.
