A round pan with a diameter of 40 cm is an essential kitchen tool for bakers who enjoy making extra-large, evenly baked, perfectly round treats. Constructed from high-quality materials such as heavy-duty aluminum or stainless steel, these pans ensure optimal heat distribution, resulting in consistent baking outcomes. The non-stick coating, typically made from Teflon or similar materials, facilitates easy release of baked items, reducing the need for excessive greasing and making cleanup a breeze.
