Instructions
Preheat the oven to 350°F. Line a 9x9-inch baking pan with parchment paper and spray with baking spray. Set aside.
Make the Brownies: In a small saucepan over medium-low heat, melt the butter and chocolate, stirring constantly until smooth. Remove from the heat and whisk in the sugar, eggs, and vanilla. Stir in the flour until just combined, then fold in the crushed Oreos. Pour the batter into the prepared pan and smooth the top.
Make the Cheesecake : In a food processor (or with a hand mixer), blend the cream cheese, sugar, egg yolk, and vanilla until completely smooth.
Drop spoonfuls of the cheesecake mixture over the brownie batter. Use a knife to gently swirl the two batters together, creating a marbled effect. Sprinkle extra crushed Oreos on top.
Bake for 30 to 33 minutes, until the center is just set. Remove from the oven and cool for at least 2 hours before slicing. You can chill the pan in the fridge to speed up the cooling.
Notes
The key here is letting them cool at least two hours before attempting to slice! Chilling them will make it even easier.
