MasterClass Smart Ceramic bakeware sets a new standard for non stick performance. The double ceramic coating is ultra durable, and ensures effortless cleaning and effective food release. So effective, in fact, that you often won't need to grease, so you can make healthier bakes with less hassle. All this is aided by the warp-resistant carbon steel core, with rolled edges for extra strength. This muffin tin has an extra wide lip, too, for easy removal from the oven . Smart Ceramic is cleverly designed as a nesting bakeware set, so as you build your collection, you can stack this cupcake tray with other pieces. All eight pieces nest into the space of the largest roasting tin. This Smart Ceramic muffin tray measures 24 x 22 cm (9½ x 8½ inches), with nine holes measuring 6.5 cm (2½ inches) wide. Like all Smart Ceramic products, it is dishwasher safe, and is BPA, PFOA and PTFE free. Be assured that this muffin tray are covered by Masterclass' five-year non-stick guarantee.
