A muffin pan is a kitchen tool used for baking muffins and cupcakes. It typically has multiple cup-shaped indentations, allowing you to bake several muffins at once. Muffin pans come in various sizes, with the most common having 12 cups. They are usually made from materials like metal, silicone, or non-stick coatings to ensure easy release of baked goods. Muffin pans can also be used for other recipes, such as mini quiches or savory snacks. They are versatile and can be found in most kitchens. Proper care, like hand washing or using liners, can extend the life of a muffin pan.
