What burger is named after singer Luther Vandross and uses a doughnut as its bun?

The burger named after singer Luther Vandross and served with a doughnut as its bun is the Luther Burger.

A Luther Burger generally consists of a hamburger patty, cheese, and a glazed doughnut cut in half in place of a conventional bun. The combination is sweet, salty, and rich, making it a novelty item as much as a standard burger.

The name refers to American singer Luther Vandross, although the burger’s exact origin is disputed. Some accounts connect it to Mulligan’s, a restaurant in Decatur, Georgia, while other stories describe it as a later fairground or restaurant creation.

The burger is sometimes confused with any burger served on a doughnut. The specific name “Luther Burger” is the established term used for this cheese-and-patty combination.
