This 12-cup muffin tin is made from heavy-gauge carbon steel, guaranteeing exceptional heat conduction and long-lasting performance. The muffin tray, also known as a cupcake tray, features a superior non-stick coating both inside and out, ensuring easy cleaning and excellent food release. It is freezer and refrigerator safe as well. You can add your ingredients, freeze them, and then place the tray directly into the oven to bake and serve fresh. This design is both practical and clever.
