It is believed that doughnuts have been tantalizing American tastebuds since Dutch settlers brought them across the sea in the early 19th century.
Some of the earliest recipes featured nuts crammed into the center of the dough -- hence the name!
Fast forward to the 21st century and doughnuts have become a snacking staple and have bolstered billions in sugary sales.
National Doughnut Day got its start in 1938 when the Salvation Army used doughnuts to raise money during the Great Depression.
It also commemorates the women who served doughnuts to soldiers during World War I.
