The debate rages -- is it donut or doughnut?

Spelling will take a backseat to savings this Friday for National Doughnut Day — or National Donut Day in some circles.

Shops across the country are marking the day with fried freebies and delectable deals.

Celebrated annually on the first Friday in June, the day of the pastry was established in 1938 to honor The Salvation Army Donut Lassies, women who served the treats to soldiers during World War I.

"The doughnut was and continues to be a symbol of the comfort and support that The Salvation Army provides to more than 23 million people in need each year," said Lt. Col. Ward Matthews, Salvation Army secretary for national community relations and development in a statement.

This year, the Salvation Army is marking the day with events across the country and has teamed up with Entenmann’s to host “Do Good Donut Parties” to deliver treats to more than 8,500 veterans. Find the events at salvationarmyusa.org.

Expect doughnut shops and bakeries to be crowded Friday even if they're not giving away free treats.

Brad Plothow, vice president of brand and communications for Womply, a small business software provider, said the made-up holiday is a big day for bakeries.

“People don’t spend more but far more people pack into bakeries looking for a treat, resulting in lots more dough for local bakeries,” Plothow said.
