The trick after that is figuring out how to adjust the baking time. There is no hard and fast rule, so you’ll have to rely on your senses and checking the cake for the usual signs of doneness, such as pulling away from the sides of the pan or springing back when you touch the center lightly.
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.
