Insomnia Cookies has been getting into the spirit of Halloween in a variety of ways. The warm cookie delivery bakery recently brought back its popular moon cakes, moon-shaped cookie cakes completed with an edible image.

The newest addition to the holiday cookie lineup is the Peanut Butter Choco-Lantern cookie. It features a double dose of chocolate, creamy peanut butter chips baked throughout, and festive pumpkin sprinkles.

The Halloween-themed cookie will make its debut on Wednesday, October 23 at all of Insomnia Cookies’ nationwide locations.

For another Halloween treat, the chain is giving away a free traditional cookie to any guest who enters a store wearing a Halloween costume. Guests can also take a picture of themselves in-store and use the hashtag #trickortreatyoself on Facebook, Instagram, Twitter, and Snapchat for a chance to win a $100 Insomnia Cookies gift card.

Additionally, Insomnia Cookies has a special Halloween deal on its website. Customers can get 10 percent off online delivery orders of $10 or more the entire week by using the code TREAT10 (the offer is valid through Monday, November 4 at 3 a.m.).
