The Ultimate Oreo Frappe features coffee, ice, and Oreo cookie pieces blended with the chain's signature vanilla soft serve, finished with whipped topping and Oreo cookie pieces.
The freebie is good for a small-sized cup of the frosty beverage and limited to one per customer.
The drink is also featured as part of Dairy Queen's current happy hour promotion, which takes place on the weekdays, from 2 to 5 PM, and offers several drinks as several discounted price points.
