The OXO SoftWorks Silicone Baking Cups are designed with a handy batter fill line that helps ensure evenly sized treats every time. The BPA-free Baking Cups can be used on a baking sheet or in muffin tins, electric pressure cookers or air fryers. Each Cup has convenient tabs that help you remove them from muffin tins without making a thumbprint, and the non-stick interior means foods release easily. The heat-resistant silicone flips inside out for thorough cleaning and is dishwasher safe. Our Cups are also great for making homemade egg bites and creating snack trays and bento-style lunch boxes.
