Oreo Drink Mix is a very real product that contains Oreo crumbles meant to be stirred into milk the way you would any other powdered product. It reportedly results in a thick chocolate milk that tastes like Oreos!
The mix is not available everywhere. A Kerry Foods representative said you can currently find it at your local Food Lion, Hy-Vee, Southeastern Grocers, Albertsons, and/or Woodman’s Markets. If you don’t have one of those near you it can also be found on Amazon.
