I gave up Oreos around fifteen years ago when my sweet tooth deserted me and I no longer craved cookies, ice cream, candy or anything of the sort. But I still like Ritz crackers with peanut butter on them.
In all my years though, I never thought to take a Ritz cracker covered in peanut butter and press it with one Oreo cookie covered with its creme filling. That never occurred to me and there may be a simple reason.
