Fat Daddio's is here to help you create delicious cupcakes or muffins with their Mini 24 Cup Muffin and Cupcake Pan. Constructed from 18-gauge anodized aluminum, these pans offer even heating, simple handling with rolled rims and it will never rust peel or flake. With the anodized aluminum, the material reflects heat rather than absorbs it. This allows the pan to heat up fast and cool down quickly.
