Muffin paper cups are round sheets of paper, foil or metal, with scallop-pressed edges, giving the muffin a round cup shape. Their shape can be compared to that of a disposable coffee filter. Muffin paper cups are used to line the bottoms of muffin pans, used in the baking of muffins to facilitate the easy removal of the finished pastry from the muffin tin.

A muffin is a type of bread that is baked in small portions. Many forms are somewhat like small cakes or cupcakes in shape, although they usually are not as sweet as cupcakes and generally lack frosting. Savory varieties, such as cornbread muffins, also exist. They generally fit in the palm of an adult hand, and are intended to be consumed by an individual in a single sitting.

Muffin can also refer to a different baked good: the smaller, disk-shaped English muffin, although this usage is uncommon outside of the Commonwealth of Nations. As American-style muffins are also sold in Commonwealth countries, the term muffin can refer to either product, with the context usually making clear which is meant.

There are many varieties and flavors of muffins made with a specific ingredient such as blueberries, chocolate chips, cucumbers, raspberry, cinnamon, pumpkin, date nut, lemon, banana, orange, peach, strawberry, boysenberry, almond, and carrot. These ingredients are then baked into the muffin. Muffins are often eaten for breakfast; alternatively, they may be served for tea or at other meals.
