Whenever I ask my son what flavor of cookie (or ice cream) he'd like, I always gets the same answer – mint Oreo. He also loves cookies (what kid doesn't?!), so I decided to make these for him. Since the dough is so soft, it's absolutely necessary to refrigerate the dough. It's kinda a bummer to have to wait for so long (8-24 hours) before baking the cookies, but the cookies will bake out like crazy otherwise. Even though though they take longer (just because of the chilling time), they are SO worth it!! They are fat and soft and full of rich, cookies-inside-of-a cookie-goodness.
