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 commonly available in 3 sizes ranging from those that bake a small or miniature muffin that is 1 to 2 inches in diameter up to tins that hold large muffins approximately 4 inches in diameter. Muffin tins may also be referred to as muffin pans.
