The Doughmakers sheet cake pan is perfect for baking delicious sheet cakes. The sheet pan measures 46 x 33 cm / 18.5 x 13 inches and is made from solid, heavy-gauge aluminum with the patented original pebble pattern textured surface. The shiny surface reflects the heat around the food for perfectly even baking and browning. The pan allows air to flow around your baked goods to ensure an easy release without using butter or oil.
