Our Slutty Brownies Recipe (Oreo Brownies) uses our favorite box of brownie mix, Oreo cookies, and a tub of store-bought chocolate chip cookie dough. Serve these slutty brownies with a scoop of vanilla ice cream or enjoy them just the way they are! If you're looking for a brownies recipe that's rich, outrageous, and guaranteed to turn heads, this slutty brownie recipe is the one to try.
Preheat the oven to 350 degrees F. Prepare a 9x13 rectangular pan with parchment paper extending the paper over the sides so that it will be easy to take the bars out later.
Press the cookie dough down on the bottom of the pan until it's evenly distributed.
Put a layer of Oreos over the cookie layer. You may need to cut Oreos in half to fit into the last row.
In a bowl combine and mix the brownie box contents, 1 egg, ⅓ c oil and ¼ cup water.( If choosing to use another brand of brownie mix, the egg, oil and water ratio may be different. Just follow box directions for whatever brownie mix you have chosen.)
Pour mixed brownie batter evenly over the Oreo layer.
Bake at 350 for 45-50 min. Test doneness with a toothpick inserted halfway between the edge and center and comes out with a few moist crumbs attached. * It's suggested to test 2 spots just in case you hit a chocolate chip or an oreo which can give an inaccurate read.
Let cool before slicing about 15-20 min.
Notes
For The Best Slutty Brownies:
Prep your baking pan with parchment paper and non-stick spray.
Do not over-bake them!
As hard as it may be, allow these to cool for a full 60 minutes before slicing and serving. You'll get nice, clean-cut servings by letting them cool first!
