A muffin is an individual-sized, baked quick bread product. Muffins in the United States are similar to cupcakes in size and cooking methods. Muffins are available in both savory varieties, such as cornmeal and cheese muffins, or sweet varieties such as blueberry, chocolate chip or banana flavours. Muffins are often eaten as a breakfast food. Coffee may be served to accompany muffins. Fresh baked muffins are sold by bakeries, donut shops and some fast food restaurants and coffeehouses. Factory baked muffins are sold at grocery stores and convenience stores and they are also served in some coffee shops and cafeterias.
