UPDATE: The Oreo Mallow Sandwich Crumbl cookie has not run on the main menu since August of 2022. All of 2023 has seen no sandwich style cookies on the main menu. Some of the testers and mystery cookies include Oreo Mallow Sandwich, Oatmeal Mallow Sandwich and Cereal Milk Sandwich ft Fruity Pebbles.
By Tuesday, August 23rd, 2022 many Crumbl Cookies stores were sold out of the Mallow Sandwich ft Oreos. There are dozens of posts on Reddit discussing this cookie being sold out and it is only Tuesday. Something that customers must understand is that if the app says sold out that does not necessarily mean that particular Crumbl Cookies stores is out of ingredients or product for the entire week. There is a possibility that there was a order of 50 Mallow Sandwich cookies and the store ran out for a brief time. Before getting disappointed, it might be a good idea to go to the store or call the store and ask them if they are out of the ingredients or just out for a short amount of time.
We heard the Mallow Sandwich ft Oreo were sold out in many Crumbl Cookies stores in Indiana, Ohio, Florida, Georgia and Tennessee. It is very likely that most of these stores will have more Mallow Sandwich ft Oreo by Wednesday or Thursday of this week in August 2022.
