Krispy Kreme Doughnuts will turn its original glazed doughnut green and reward thousands of fans with free doughnuts for a year during this year’s St. Patrick’s Day Weekend celebration.

Krispy Kreme is bringing back its popular “O’riginal” Glazed doughnut, a St. Patrick’s Day twist on the brand’s iconic doughnut with specially formulated green dough. The doughnut will be available throughout the three-day celebration, Friday-Sunday, March 15-17 at participating shops in the U.S.

The fun doesn’t end there. For the first time, thousands of lucky Krispy Kremefans will win a “Golden Dozen Pass” worth free Original Glazed doughnuts for a year—one dozen per month through St. Patrick’s Day 2020. Multiple customers will win a Golden Dozen Pass each day at every participating shop.

“What could be better than a green O’riginal Glazed doughnut? Not much. But free Original Glazed doughnuts for a year might do the trick. Stop by and maybe you’ll end up with both,” says Dave Skena, chief marketing officer for Krispy Kreme Doughnuts.
