Bake sheets are commercial-grade baking pans specially sized and designed for bread, cake and pastry making. Their heavyweight aluminum structure transfers heat evenly so that baked goods cook to a perfect golden brown, every time. Its reinforced beaded rim prevents warping, and adds strength and durability that enables thousands of uses at a wide range of temperatures (up to 480-degrees Fahrenheit). It’s great for chilling and freezing foods, too. Simply line the baking pan with parchment or a baking mat, place items to be baked or frozen onto the baking pan, and pop it in the oven or freezer.
