Insulated so cookies won't scorch, this cookie sheet combines two layers of commercial-gauge nonstick steel with a pocket of air so cookies bake evenly and emerge golden brown. The durable construction will not chip, peel or warp, and it cleans up easily, too. Three open sides allow air to circulate, while a lip provides a stopgap to facilitate easy cookie removal. If you like chewy cookies, this is the pan for you. Dishwasher-safe. Made in England. 16" x 14".
