(NEXSTAR) – National Cookie Day comes just once a year, and there really is only one way to celebrate — with cookies. The first cookies are believed to date back as early as 7th century A.D. Persia, according to a timeline from DoDo Edible Cookie Dough & Ice Cream. By the end of the 14th century, cookies were available throughout Europe and would go on to spread into America.

Now, centuries later, cookies have become so beloved that we’ve set aside an entire day — Dec. 4, National Cookie Day — to honor the sweet treat. Retailers, too, are offering freebies and deals to mark the holiday.

Whether you make your own or seek out a warm cookie from your nearest bakery, it’s not that hard to indulge. Here’s where you can find some of the best deals on December 4:
