Super durable, lighter than cast iron and oh, that gorgeous unexpected blue. Perfect for baking cupcakes, muffins or mini quiches, our 14-piece bakeware set is part of our exclusive Essentials 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 pans heat quickly and maintain consistent temperatures for perfectly browned baked goods. The double layer of silicone-based non-stick coating ensures easy release and quick cleanup.
