Muffin molds are kitchen tools used to shape and bake muffins or cupcakes. They are typically made from materials like silicone, metal, or paper, and come in various sizes and shapes. The molds help create uniform portions, ensuring even cooking and easy removal of baked goods. These molds can be found in different configurations, such as standard, mini, or jumbo sizes. Some muffin molds are non-stick, making it easier to release the baked items without sticking. Using muffin molds can enhance presentation and simplify the baking process for both novice and experienced bakers.
