A donut hole is the center of a donut that got cut out. Some people, mostly children, wonder what happened to the hole in the center of the donut; Donut hole is their answer. One might say that donut hole was liberated from its oppressive surrounding dough, against all odds.
Donut hole is great. It offers an eater the opportunity to have donut, without committing to more than one bite. They are normally glazed, which makes them sticky, which makes them not that portable.
Donut Hole became an official snack on July 4th 2012.
