From All-Clad， this cookie sheet features:

Despite being named after a sweet， spongy dessert， this pan is as tough as they come. It’s capable of withstanding baking temperatures up to 450°F without getting bent out of shape. Its oversized handles are easy to grip， so you can bring it in and out of the oven between batches or check on your goodies with ease. Like all the pieces in our Pro-Release Bakeware Collection， it’s made from heavy-gauge aluminized steel， a responsive material that heats up quickly and maintains consistent temperatures throughout， so everything bakes evenly. Plus， its surface is coated with a ceramic-reinforced， PFOA-free nonstick coating so your desserts slide right off.

• Features a large open surface (approx. 12" x 17") with angled edges for easier carrying
• Made from commercial grade aluminized steel that is warp resistant (oven safe up to 450°F)
• Coated with a food-safe PFOA-free nonstick material that releases food easily batch after batch

• The go-to cookware brand for professional chefs and avid home cooks and bakers alike
