Perfect baking every time—our exclusive marble-finish muffin pan combines the stability of metal bakeware with the flexibility, nonstick performance and quick cleanup of silicone. An integrated steel rim gives the pan structure and secure handling, while the highest-quality European silicone cools quickly and lets you pop out your baked creations without the need for utensils. Structure Silicone is dishwasher safe and is resistant to thermal shock, allowing it to transport safely from freezer to oven. Family owned since 1889, Trudeau backs up their bakeware with a lifetime warranty.
