So, my colleague and I were talking about the "Cookie Stuffed Cookie" recipe that I saw on here, and we thought about perhaps making a bet and actually making it if we met certain metrics for the week at work (long story). Anyway, so I wanted to try it, but I was wondering if anyone else had tried to make it and whether or not it turned out, and what cookies you used for it? I wanted to surprise him by making it, but there are so many cookie varieties to choose from! Oreos, shortbread, Keebler Fudge Grahams, even, right? What would you suggest?
