King Arthur Baking Company Cookie Mat

King Arthur Baking Company Cookie Mat ensures perfectly spaced and shaped cookies every time, preventing edges from touching and causing misshaped results. Made from durable silicone and natural glass fibers, this mat is heat safe up to 500 degrees Fahrenheit and measures 16.5 x 11.5 inches with a thickness of 0.4 millimeters. The non-stick surface allows baked goods to release easily without tearing or crumbling, while the permanent size markings ensure consistent use over time. Designed to fit U.S. half-sheet baking pans, the mat features polka dot marks for accurate dough spacing and border marks for creating strips or sheets up to 11 x 16 inches. It rolls up easily for storage and is dishwasher safe, though cutting on the mat with metal blades should be avoided to maintain its quality. Model Number: 50176K
