One of the great things about Crumbl Cookies is their longevity. Meaning, if you buy a six pack of cookies on a Monday or Tuesday, they will taste good and (somewhat) fresh all the way until Thursday of Friday. Note that Crumbl offers cookies warmed or chilled. If you purchase a chilled Crumbl cookie, you will likely want to put it in the fridge. You do not have to, but that is what makes them have the correct texture and taste.
While the served warm cookies are always best just after a purchase, they tend to stay tasty and mouth watering for up to 72 hours. The time frame is similar for served chilled cookies but can be shorter. To save yourself the hassle of having to eat cookies you do not like or having to throw Crumbl Cookies away, try to eat chilled cookies within 48 hours of purchase. This will give you the best texture and taste. The best taste is going to be right after purchase at your local Crumbl Cookies store but most do not want to put 75 grams of sugar in their body in one sitting.
A protip for those that buy a six pack of Crumbl Cookies is to cut each cookie into four or five pieces like a small pie and let the family try a little bit of each cookie. Most people are not going to be able to consume an entire Crumbl Cookie in one sitting. If they do, they will likely go into a sugar coma within the hour. Drink a Mountain Dew with your Crumbl Cookie and see how your body feels.
There are many Reddit threads discussing ways in which Crumbl fans can buy a six pack or 12 pack of a popular cookie such as the Mallow Sandwich ft. Oreo and refrigerate/freeze them. There are ways in which Crumbl customers can vacuum seal the cookies and they are good for months in the freezer. After taking them out of the freezer, they can be thawed and warmed up in the oven. This is something many people are doing now instead of waiting until they see their favorite flavor again.
