A type of pan used for baking muffins. The pan typically will have 6 or 12 individual round pockets or holders connected to the tin and formed in the shape of a muffin. The muffin batter is poured into the individual pockets and as the muffin bakes, a top forms over the pocket while the base of the muffin is baked in the shape of the cup. Muffin tins are also often used to bake cupcakes. The tins are commonly available in 3 sizes ranging from those that bake a small or miniature muffin that is 1 to 2 inches in diameter, standard muffins that are 2 3/4 inches and large muffins approximately 4 inches in diameter. Individual muffin cups made from silicone are also available for baking individual cupcakes and muffins. Muffin tins may also be referred to as muffin pans.
