These are some hyper-elaborate cookies the recipe for which is found in the Milk Cookbook. These are sorta like rice-crispie-bar cookies because you use marshmallows but they are made with corn flakes instead and mini-chocolate chips are tossed in for fun. You have to make the elaborate dough and then refrigerate balls of it for 24 hours.
The cookies turn out to be enormous. They are delicious. Worth the effort and if I ever truly get the hang of the process I will make them more often.
