These Oreo Cheesecake Brownies are the absolute BEST! A layer of chocolate brownie batter, crumbled Oreos in the middle, and another layer of creamy cheesecake filling. Top it all off with some extra Oreo cookie crumbles and a chocolate syrup drizzle for the ultimate treat!
Line a 9x9 or 11x7 baking pan with parchment paper.
Make the brownie mix according to directions and pour into the pan.
Top with the crumbled Oreos and bake for 24-27 minutes (depending on the pan size, see brownie mix directions). TIP: It's best to slightly under-bake them if possible!
Make The Cheesecake Layer
While the brownies are baking, beat the cream cheese, sugar, and sour cream until smooth.
Add in the egg and vanilla extract, then mix until smooth.
Pour the cheesecake filling layer over the brownie layer.
Add Toppings
Top with more crumbled Oreos and chocolate syrup (optional).
Bake for 35-40 minutes.
Let cool for 30 minutes at room temperature, then refrigerate for 30 minutes or more.
