Cupcake liners are small, often colorful paper or silicone cups used to hold individual cupcakes during baking. They help prevent the batter from sticking to the pan and make it easier to remove the cupcakes once they are baked. Liners come in various sizes, shapes, and designs, allowing for creative presentation. In addition to their practical use, cupcake liners can enhance the visual appeal of baked goods. They are available in many patterns, including solid colors, polka dots, and themed designs for special occasions. Using liners can also simplify cleanup, as they catch crumbs and residue from the cupcakes.
