This heavyweight half-sheet bake sheet, also called a bun pan, is a commercial-grade baking pan specially sized and designed for bread and cake baking. Made from heavyweight aluminum, it transfers heat evenly so that rolls, breads, cakes, cookies, pastries and other baked goods cook to a perfect golden brown. Its reinforced beaded rim keeps it from warping and adds strength and durability to outlast thousands of uses at a wide range of temperatures(up to 480-degrees F). It’s great for chilling and freezing foods, too. Simply line the baking pan with parchment paper or a baking mat, place items to be baked or frozen onto the pan and pop it in the oven or freezer. Mrs. Anderson’s Baking Pans are durable and reusable with a non-porous surface for better kitchen safety. To clean, simply wash with a damp sponge and mild detergent and air dry. This half sheet baking pan is designed to perfectly fit Mrs. Anderson's Nonstick Silicone Baking Mat and Cooling Rack,(both sold separately). Complete instructions included. Cautions: Do not use knives, scrapers, brushes or cutters, or place in the dishwasher.
