The Cooking Actress or Martha Stewart if you want to try it, but I'm not sure I recommend it. The high sugar content means these overcook easily and turn crunchy even more easily. Something isn't quite right about the recipe, and I'd have to play with it a little bit to see what I could make better.
The cookie pictured is one of mine, but not all of them looked so pretty. It could be that I just have a bias against crunchy cookies.
Momofuko Milk Bar sells these for $2 a piece, so they have it figured out. The cornflake crunch, an element in the cookie that has to be made first, has powdered milk in it which adds an interesting flavor. Also salt. That added to the 1.5 tsp salt also made them saltier than I really like.
