From USA Pan, a Pennsylvania company that manufactures a superior line of commercial grade bakeware, this large (18" x 14") cookie sheet turns out the most perfectly baked cookies that no kitchen should be without it. It is constructed from heavy gauge aluminized steel (60% recycled) and has a unique fluted surface that adds strength and facilitates air circulation for even baking. Each pan is coated with clear, non-stick, environmentally friendly silicone that is specially formulated for baking. The cookie sheet, and all USA Pan bakeware,is PTFE and PFOA-free. Molly has requested two cookie sheets, because Mark loves cookies!
