If you've never made slutty brownies before, you're in for a treat! This easy recipe is sweet, delicious, and downright sinful, just like the name suggests!
Preheat the oven to 350 degrees F/175 degrees C.
Grease a 9x9 baking dish with cooking spray, oil, or butter and line with parchment paper.
Carefully spread the cookie dough into the pan, pressing down into an even layer.
Top the cookie dough with an even layer of whole, uncut Oreos.
Make the brownie batter according to the instructions on the box.
Pour the brownie batter over the Oreos and cookie dough, careful not to disturb the Oreos.
Bake for 40 to 45 minutes, checking after 40 with a toothpick in the middle.
Allow the pan to cool for 15 minutes before carefully lifting it out and cutting it into squares.
