New York City cookie dough bakery DO is getting ready for the festivities of National Cookie Dough Day, taking place Friday, June 21. There will be a variety of offers in-store, at its Chicago pop-up, and online.

In New York City, DO will be popping up in surprise locations around the city with free cookie dough. The bakery will reveal those locations on Instagram throughout the day on National Cookie Dough Day.

At DO’s pop-up location at Chicago’s Navy Pier, the first 25 people that show up will get a free scoop of a special flavor.

Both in-store and online, DO will have special discounts. At its flagship location and its pop-up on the Dumbo waterfront, customers can get a scratch off card that will reveal a discount. The store will also host a party complete with a photo booth, exclusive free samples, and more.

Additionally, DO will be bringing treats to seven special offices around the U.S. Entrants must nominate a co-worker that embraces “the cookie dough way of life” by making the office sweeter, and the winners will each receive a cookie dough party.
