As Seen on ITV's Cooking With the Stars! Bake a batch of perfect treats every time with the MasterClass Double-Layer Non-Stick Baking Sheet. This baking sheet features two layers of heavy-duty carbon steel. The slight air gap between the layers helps it distribute the heat from your oven evenly across the sheet, even if you’re using a standard convection oven. This makes it ideal for heat-critical bakes like meringue and certain biscuits. At 35 x 28 cm (14” x 11”), the oven sheet is large enough to bake generous batches of shortbreads, Linzer biscuits or chewy flapjacks. For your peace of mind, this baking sheet is covered by the MasterClass 20-year guarantee and a 5-year non-stick guarantee.
