The holiday season is called the most wonderful time of the year for a reason, and it probably has something to do with one of the sweetest times of the year: National Cookie Day!

The day, which celebrates all kinds of sweet treats and delicious cookies, means that some of your favorite cookie bakeries and cafes are offering ways for you to partake in the celebration with free and discounted cookies. And nothing says Happy Holidays like getting a free cookie to bite into!

Here's a full list of places where you can enjoy some yummy cookies:
