Sunday, June 21 is an important day, as Father’s Day will take place then, but the day will be a little sweeter this year as it’s also National Cookie Dough Day.

DO, Cookie Dough Confections has a lot planned for that day. As part of its celebration, the cookie dough bakery is holding a once-a-year sale with special offers. Customers can sign up for the email list to be the first to get access. Additionally, five customers who place an order between now and June 21 will receive a surprise golden ticket with their order, winning a one-of-a-kind prize.

Fans can also enter for a chance to win a year of free cookie dough. DO will post contest details on its Instagram page on Thursday, June 18.

On Friday, June 19, DO will make a special recipe from its cookbook, Hello, Cookie Dough, on Instagram at 4:30 p.m. EST. DO will provide the ingredient list and everything fans need to follow along on Instagram beforehand.

Finally, all orders placed on DO’s delivery platforms and for in-store takeout on June 21 will include a free cookie dough treat with purchase.
