These slutty brownies are the most over-the-top dessert you'll ever try. They have a soft and chewy chocolate chip cookie base, a layer of Oreo cookies, and fudgy brownie on top! This recipe is 100% from scratch and definitely the most indulgent brownie recipe around.
Preheat the oven to 350F (180C) degrees.
Lightly grease a 9x13 inch (23x33 cm) pan. Then line parchment paper and leave an overhang around the sides. Greasing the pan first helps the paper stick. Alternatively, simply grease the pan.
In a large bowl, beat together the butter, brown sugar and granulated sugar until combined.
Place the Oreo cookies on top of the cookie dough pressing them down just slightly. I got 7 rows of 4 cookies, plus I added a few half cookies on each row to completely cover the cookie dough layer.
Finely chop the chocolate. Place the chocolate and butter into a large heatproof bowl. Microwave on medium power for 45-second intervals. Remove from the microwave between each interval and stir the batter. **Do not microwave on high power or the chocolate can become grainy or burn.
Bake the brownies in the preheated oven for 37-45 minutes, or until an inserted toothpick comes out dry or with a few damp crumbs. Bake time will vary depending on your oven and how gooey you like your brownies.
