Chicago’s Warm Belly Bakery is known to think outside-the-box when it comes to its cookies. In the past, the bakery has offered CBD-infused treats, and now it is looking to appeal to dieters with its latest offering.

Warm Belly Bakery’s new Double Chocolate Walnut Keto Cookie is a ketogenic (keto) diet-friendly cookie made with an almond flour base that is low in carbs, low in sugar, and gluten-free. Each cookie contains only 2 grams of net carbs.

The new cookie is available at Warm Belly Bakery’s two Chicago locations at a cost of $4 each, and can also be ordered for delivery through Doordash, UberEATS, Grubhub, and Postmates.

Warm Belly Bakery first opened in 2016, and has since gained a big following. It offers over 70 flavors of cookies, with a daily rotation of around 12 flavors of gourmet cookies, plus muffins, Danishes, pound cakes, and seasonal offerings.
