There are a few different materials that waffle plates can be made of. The material needs to be able to withstand high heat, as well as be able to distribute heat evenly. Waffle maker plates can be made of ceramic, but they can also be made of cast iron, cast steel, and cast aluminum. Many waffle maker plates will also have a non-stick coating on them. The bonus of having ceramic waffle plates is that they typically don’t need any non-stick coating. They are easy to clean and batter will not stain them. Ceramic and non-stick coating also makes it easy to cook waffles or other items without having to douse the plates in cooking spray.
