Dunkin' Donuts said it sold 4.6 million croissant donuts since the bakery chain first introduced its version of the croissant-doughnut last month. The company called it one of the most popular limited-time items in its recent history.
Dunkin' said it will extend the Croissant Donut promotion into 2015 at participating locations throughout the country "based on popular demand."
"The positive customer response to our Croissant Donut reflects the success of our strategies focused on providing guests a menu that offers a combination of old favorites like our Original Blend Coffee and innovative and fun new products like the Croissant Donut," the company said in a statement.
Dominique Ansel Bakery in New York first introduced its now-trademarked Cronut over a year ago. National chains, includingDunkin and Jack in the Box, followed suit with similar products with different names.
Dunkin's version of the croissant-doughnut hybrid is priced at $2.49, more than twice the price of its regular doughnuts, but half the price of Dominique Ansel's Cronut.
