Doughnut chain Voodoo Doughnut has gotten into the spirit of St. Patrick’s Day with a limited-time doughnut that celebrates the symbol, color and flavor associated with the holiday.

The Shamrock is a minty fresh doughnut filled with mint Oreo buttercream and topped with green vanilla frosting. It’s available online, for delivery or pick-up at all Oregon, Denver and Texas locations from March 17-21.

Denver is set to get a third Voodoo Doughnut location later this year. The chain has announced that it will open in Concourse B of Denver International Airport before the end of 2021, giving travelers the opportunity to enjoy its doughnuts.

Voodoo Doughnut currently has ten locations in the United States: four in Oregon (three in Portland, one in Eugene), two in Denver, Colorado, one in Austin, Texas, one in Houston, Texas, one at Universal CityWalk in Universal Hollywood and one at Universal Resort in Orlando, Florida.
