Muffin
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.
In Commonwealth countries muffin can also refer to a disk-shaped English muffin. 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, baked into the muffin. Muffins are often eaten for breakfast; alternatively, they may be served for tea or at other meals.

On the other hand, the baked muffin, even if from a mix, seemed almost healthy compared to the fat-laden alternatives of doughnuts and Danish pastry. "Healthy" muffin recipes using whole grains and such "natural" things as yogurt and various vegetables evolved rapidly. But for "healthy" muffins to have any shelf-life without artificial preservatives, the sugar and fat content needed to be increased, to the point where the read more at » http://en.wikipedia.org/wiki/Muffin
