Fun facts about the American celebration of National Donut Day. National Donut Day is celebrated on the first Friday in June. More than 10 billion donuts are made every year in the U.S. alone. The largest donut ever made was a 1.7 ton jelly doughnut, which was 16 feet in diameter and 16 inches high in the center. Adolph Levitt invented the first donut machine in 1920. The Dutch are credited with bringing doughnuts to North America with their olykoeks, or oily cakes in the 1800s. The Guinness World record for donut eating is held by John Haight, who ate 29 doughnuts in just over 6 minutes. Now consider this: Per capita, Canada has more donut shops than any other country. Yet we don't celebrate the donut day here. Another missed Canadian opportunity.
