Old Fashioned

Old-fashioned doughnuts are cake doughnuts that tend to have an irregular sort of indented ring shape, like a flying saucer, as pictured above.

(Some have a more prominent indentation or more jagged edges than others.) They tend to have a bit more crunch on the outside, both by nature of the style and due to the increased surface area. An "old-fashioned doughnut" generally suggests a plain sweet base, though chocolate old-fashioned doughnuts are quite prevalent as well.
