Super durable, lighter than cast iron and oh, that gorgeous unexpected slate blue. Ideal for sheet cakes, cornbread and pull-apart 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 rectangular 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. The sturdy lid lets you take your creations on the go or keep them fresh at home. Designed with enough height to accommodate up to two inches of frosting, the lid ensures safe transport of precious baked goods and cleans up easily in the dishwasher.
