This cupcake and muffin pan has 12 standard size wells made from heavy duty aluminized steel. It features an Americoat silicone coating (which is PTFE, PFOA, and BPA free) to promote a nonstick outer for quick and easy clean up. The unique fluted surface design enhances the nonstick qualities and adds strength to resist warping from regular use. The aluminized steel allows for perfect heat distribution and increased air flow, so you’re guaranteed with evenly baked goodies. When done, simply wash with hot water, mild soap, and a gentle scrub brush or sponge.
