The Irish outlet of the US doughnut maker Krispy Kreme has sold more than 6.6 million doughnuts in the past year.
The company says this makes it the brand's "most successful store opening internationally."
The Dublin shop, based in Blanchardstown, is marking one year open on Thursday.
The company's Original Glazed doughnut is the most popular, selling over 2.3 million units since the store opened.
That equates to one glazed doughnut sold every two minutes - visually, this would be a line of doughnuts side by side stretching from Dublin to Dundalk and back.
The next most-popular is the Nutty Chocolatta doughnut, and the Krispy Kreme single 'Bites'.
While on Valentine's Day alone, over 10,000 heart-shaped doughnuts were served.
Krispy Kreme says its coffee has come also out on top as the hot beverage of choice to accompany the doughnuts.
The store has served 120,000 coffees and 22,000 cups of tea within opening year.
To mark its first birthday, the company has created a limited edition 'The O'riginal Party' doughnut.
The signature-glazed ring is hand dipped in candyfloss-flavoured icing; vanilla flavoured frosting and finished with sprinkles.
Alex Drysdale is Krispy Kreme country director for Ireland: "This year has been truly remarkable for the brand and I speak for the entire team at the store when I say a big 'thank you' to all our customers for making it a year to remember.
"Thursday is not just about celebrating our 'first birthday' in Ireland, it is about our customers and I would encourage everyone to visit the store across the day to enjoy the party and of course share a doughnut or two".
