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.
Before baking a half sheet cake, butter and flour the cake pans, and add a layer of parchment paper to the bottom of each pan. This makes it easier to remove the cakes without them breaking once they have cooled. Never attempt to take a warm cake out of the pan. To assemble a half sheet cake from two smaller cakes, place the cakes side by side, with the long sides touching, on a cake board.
