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.
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.
