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.
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.
