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.
While sheet cake pans are available in a variety of materials and styles, the most important thing to consider while shopping is the size. Sheet pans are measured Length x Width x Height, with the height or depth generally ranging between 1 and 4 inches.
