Donuts or doughnuts? No matter how you spell them, they're delicious.

Whether you like 'em deep-fried, cake-style, stuffed with jelly or cream, sprinkled with powdered sugar, sprinkles or chocolate-frosted, these doughy delights are undeniably delicious.

National Doughnut Day was created in 1938 when the Salvation Army used the pastry to raise money during the Great Depression and to honor the women who served doughnuts to soldiers during World War I.

To help celebrate National Doughnut Day, plenty of national and local places are offering sweet deals and discounted donuts.

Today, Dunkin Donuts is giving out a free donut with any beverage purchase. If Krispy Kreme is more your style, pick up a free donut at any of their U.S. or Canadian locations, no purchase necessary.
