Bake cookies effortlessly with our exclusive set. Our cookie sheet in gorgeous slate blue is part of our bakeware collection that takes its cue from professional kitchens. Made of carbon steel—an alloy of 99% iron and 1% carbon that's nearly indestructible—the pan heats quickly and evenly for consistent baking and perfect browning. Reinforced rims prevent warping, while two flat sides allow baked cookies to slide right off . Designed to bake without parchment, butter, oil or spray, Silpat's ingenious mat bakes cookies evenly and releases them easily. Simply place the pan on our cookie sheet, add dough and bake as usual. Made with food-grade silicone and reinforced fiberglass mesh, the cookie mat cleans up easily in the dishwasher.
