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.
It is virtually impossible to torte (cut in half) a sheet cake without it cracking or crumbling. Always chill the sheet cake if you are going to torte it so it is firm and cuts smoothly. Nevertheless, it is better to bake the layers in separate pans.
