Naturally Non-Stick for Healthy Baking Hungry for some warm chocolate chip cookies? The Great Grand Cookie Sheet is large, which makes it perfect for baking big batches of cookies. Made of premium heavy gauge, recyclable aluminum with strengthened handle areas, the baking sheet features a pebble pattern, which allows for airflow under baked goods for more even browning and quick release. Your cookies will slide right off! This non-coated bakeware's unique, natural non-stick properties mean consistent, reliable and healthy results every time. No need to grease the pan with oil, butter or shortening. Aluminum heats up faster, cools down faster and bakes more evenly than any other surface. More durable than non-stick and aluminized steel (scratching doesn't affect performance of the pan). Hand wash. Material: Commercial grade 18 gauge aluminum. Dimensions: 14" x 20.5" x 0.25". Weight: 1.4 lb. Origin: China. Care Instructions: For best care, hand wash promptly in hot soapy water and dry before storing. Avoid detergents with a chlorine base.
