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.
Line a 9x13 inch pan with parchment paper and leave an overhang around the sides.
Chocolate Chip Cookie Layer
Beat together the melted butter, brown sugar and white sugar.
Beat in the eggs and vanilla extract.
With the mixer on low speed, beat in the flour and salt.
Turn off the mixer and stir in the chocolate chips using a rubber spatula or wooden spoon.
Spoon the mixture into the prepared pan, and spread smooth with a spatula.
Place the Oreo cookies on top of the cookie dough pressing them down just slightly. I got 6 rows of 4 cookies.
Add the butter and chocolate to a large heatproof bowl. Microwave on medium power for 45 second intervals, stirring between each, until melted.
In a separate bowl, whisk together the eggs and sugar.
Whisk the chocolate mixture into the egg mixture.
Gently fold in the flour, cocoa powder and salt using rubber spatula or wooden spoon.
Pour the brownie batter over the Oreo cookie layer, and spread the top smooth as needed.
Baking and Cooling
Bake the brownies in the preheated oven for 50-55 minutes, or until an inserted toothpick comes out dry or with a few damp crumbs. If you notice the top is starting to burn, cover with aluminum foil and continue baking. I first check my brownies at 45 minutes just in case.
Cool the brownies fully (at least 4 hours) before slicing for clean, even cuts.
Store leftovers at room temperature in an airtight container for up to 4 days.
Semi-sweet chocolate can be substituted for dark chocolate. However, I wouldn't use a chocolate that's more than 60% cocoa.Recipe can be halved and made in a 9x9 inch pan, the bake time will be about the same or slightly shorter.
