So here's the dish on how you make these. I hope you have plan for hiding them because once your family/friends/coworkers get a taste - you're going to have to work hard to keep them to yourself.
What you'll need:
1 brownie mix and oil/water/eggs to make mix
1/2 batch of back to school cookie dough
12 Oreo's (I used double stuffed because let's be honest we aren't trying to save any calories here)
1 7 oz jar of marshmallow cream
What you do:
Prepare the brownie mix according to package directions. Pour into the bottom of a 9 x 13 inch, greased pan. Lay Oreo's in batter. Drop spoonfuls of marshmallow cream between Oreo's but don't let it touch the side. Roll out cookie dough like you would sugar cookies. Lay it accross the top of the Oreo/cream/brownie layers. Bake at 350 for about 20-25 minutes or until cookie dough is golden brown. Cool before serving. (Or, for heaven's sake, grab a large spoon and just dig in. Oh, darn, I just had a wicked thought. Top with chocolate ice cream and hot fudge.)
