Krispy Kreme is offering a free dozen Grinch green glazed donuts

The Grinch loves a good Krispy Kreme doughnut!

The popular bakery “transformed into Who-Ville overnight” and turned all the original glazed donuts green. Krispy Kreme is now offering a free original glazed dozen — including the special Grinch Green Dozen — with the purchase of a dozen at regular price.

The offer will only be available December 13th and 14th in store or drive-thru. The limit is two dozen per guest, while supplies last.

The arrival of the Grinch Green Dozen deal comes after Krispy Kreme changed its annual Day of the Dozens deal — which typically offers an original glazed dozen for $1 with the purchase of another dozen — to a buy one, get one free deal .

Krispy Kreme posted a few videos on Instagram of the Grinch sneaking into one of its stores, eating a few donuts and coloring the donut dough a fluorescent green. The Grinch bore a striking resemblance to Jim Carrey’s version of the beloved Christmas villain.

Another video saw the Grinch again in the Krispy Kreme kitchen, this time working with employees to create the perfect green doughnut.

On November 29, the chain introduced three new ones How the Grinch Stole Christmas!-themed donuts.

The trio of offerings in the Merry Grinchmas Donut Collection are each inspired by a different character from the beloved Dr. Seuss story: Grinch Doughnut, Grinchy Claus Donut and Cindy-Lou Who Merry Berry Tree Doughnut.
