Muffin cups are small, often paper or silicone containers used to hold muffin batter while baking. They come in various sizes and designs, making it easy to create individual servings of muffins. Muffin cups help prevent the batter from sticking to the pan and simplify cleanup after baking. These cups are commonly used in both home kitchens and commercial bakeries. They can be found in standard sizes, such as mini, regular, and jumbo, allowing for a variety of muffin sizes. Muffin cups are also available in colorful patterns, adding a decorative touch to baked goods.
