Super durable, lighter than cast iron and oh, that gorgeous unexpected blue. Ideal for layer cakes, cornbread or pecan rolls, our slate blue cake pan is part of our exclusive 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 round cake pan heats quickly and maintains consistent temperatures for perfectly baked foods. A double layer of silicone-based non-stick coating ensures easy release and quick cleanup.
