King Arthur Baking Company's Reusable Nonstick Silicone Liners make it easy to release baked goods from round cake baking pans. Simply place a liner into an 8-inch round pan, spray the pan sides, add the batter, and bake according to the recipe. Once done, allow the cake to cool slightly, release its edges from the pan, turn the cake out, remove the liner, and allow the liner to cool completely before handling or cleaning. Made from European-grade silicone with natural glass fibers and sealed edges, it distributes heat evenly, offers the same quick food release and easy cleanup as standard silicone but is even more durable, and maintains its non-stick qualities through more uses. It's strong, durable, and flexes for easy removal from baked goods. Use only plastic utensils or cutters and press gently to keep from scoring the liner. Avoid contact with direct heat, like stovetops or hot plates. It's heat safe to 500-degrees Fahrenheit, safe for microwave and dishwasher use.
