Designed to promote even baking and browning of quick breads and mini-cakes, our pans release baked goods in perfect shape and clean up in seconds. The pans boast two layers of technologically advanced Swiss-made Goldtouch™ nonstick coating, a ceramic-reinforced nonstick surface that will not chip or peel and is highly scratch resistant. To withstand frequent use, the nonstick layers are bonded to commercial-gauge aluminized steel, the same construction used by professional kitchens because it distributes heat quickly and evenly, producing consistent baking results. A thick band within each pan's lip increases durability and prevents warping or flexing. Dishwasher safe. 5 3/4" x 3 1/4" x 2 1/4" high. Made in the USA. Set of four. A Williams-Sonoma exclusive.
