Got a cookies & cream lover in your life? Make them these bars! A dense, fudgy brownie is layered with creamy vanilla cheesecake and topped with crunchy bits of Oreos. So chocolate-y and creamy, you'll swoon!
Line the pan with a sheet of parchment paper, allowing the excess to hang over the sides of the pan.
Place the sugar, butter, cocoa, and salt in a large mixing bowl, and microwave (in 30-second increments) until the butter has melted. Stir until combined.
Add the eggs, one at a time, stirring after each addition until completely incorporated.
Stir in the flour and vanilla, and transfer the batter to the prepared pan.
Bake for 30 minutes. Cool slightly before topping with cheesecake mixture.
Make the Oreo cheesecake layer:
Preheat the oven to 350 degrees F.
Place the cream cheese, sugar, and cornstarch in a large mixing bowl, and beat on medium speed until creamy.
Add the eggs, one at a time, scraping the bottom and sides of the bowl after each addition. Stir on low speed until completely incorporated.
Stir in the cream and vanilla, and pour the mixture over the partially baked brownies.
Top with Oreos and bake for 15 minutes, then lower the oven temperature to 250 degrees F, and bake for an additional 35-40 minutes, or until the cheesecake is set around the edges and just barely jiggly towards the center.
Cool completely (or preferably, chill overnight) before cutting into bars.
