Enjoy the perfect CHEWY cookie every time you bake with on Calphalon's insulated cookie sheets! Say goodbye to dry burned cookies, the insulated layers create a barrier that slows down the cooking process just enough to insure moist chewy results! The heavyweight aluminized steel distributes heat evenly, helping you bake evenly every time. Cookies release cleanly and completely and clean up is a breeze, thanks to our reliable nonstick bakeware surface.
