Friday is National Doughnut Day

Mmmmm, donuts. Mmmmm, donuts.

(WTVM) - If you have a sweet tooth, go ahead and rejoice – Friday is National Doughnut Day!

The day was started by the Salvation Army in Chicago in 1938. It honors the group's "donut lassies," who served treats and provided help to soldiers on the front lines during World War I.

And in case you were wondering, doughnuts didn't always have that hole in the middle.

It wasn't until 1847 that the holed-out doughnuts we know and love today appeared.

Doughnut shops and chains across the US are offering free doughnuts on Friday. Krispy Kreme is offering one free doughnut to anyone who stops by the restaurant.

Dunkin Donuts is giving away a free doughnut with the purchase of a drink.
