National Doughnut Day 2013: Where to Get Free Doughnuts June 7 is National Doughnut Day. Whether you're partial to the cream-filled, glazed, jelly or chocolate varieties, the doughnut is something near and dear to so many of us. The Salvation Army established this sweet holiday in 1938 to raise funds during the Great Depression and honor the "lassies," as they called the female volunteers, who supported the soldiers on the front lines during World War I, serving them delicious meals, and of course, doughnuts. Approximately 250 "lassies" provided assistance to American soldiers in France in 1917. Fast forward to 2013 and many national chains and smaller shops are offering free doughnuts to celebrate. Krispy Kreme Krispy Kreme will be giving away a free doughnut of any variety to every customer at participating locations, while supplies last. No purchase necessary. Click here to find a store near you. Dunkin" Donuts At Dunkin" Donuts, customers will receive a free doughnut with any beverage purchase. The chain's much-buzzed about Glazed Donut Breakfast Sandwich also makes it debut on the permanent menu at Dunkin" Donuts restaurants today. The 360-calorie sandwich features bacon and a pepper fried egg on a glazed yeast ring donut. If you try one, let us know what you think in the comments!
