Other forms: muffins
A muffin is a small baked good made from batter. Don't kid yourself: the only real difference between a slice of cake and a muffin is the shape.
Muffins are single-serving quick breads, which rise with the help of baking soda or baking powder and eggs instead of yeast. They tend to be sweet and somewhat moist, but heavier than a cake or cupcake. Muffins are baked in a pan with cup-sized indentations. The word was originally moofin, which may come from the Low German muffe, "small cake," or the Old French moflet, "soft or tender."
