This bakeware set is an exceptional value, including all basic pieces to equip your kitchen. Made of heavy weight carbon steel to aid in even browning. The nonstick surface makes cleanup easy and allows you to bake cookies without greasing the pan. The color of a baking pan influences the browning of your baked goods – the darker the color, the more browning occurs. Our nonstick cookie pan is a light gray color to prevent overbrowning.

Cooling Rack Features: Best in class, durable nonstick lets baked food slide off and is easy to clean. Heavy gauge construction resists warping. Anolon SureGrip® silicone handles are slip-free and comfortable. Oven safe to 500°F/260°C.
