Ingredients
Method
Prep the Pan:
- Preheat your oven to 350°F (175°C).Grease and line an 8x8-inch (20x20 cm) square baking pan with parchment paper, leaving an overhang for easy removal.
Make the Cream Cheese Layer:
- In a medium bowl, whisk the cream cheese, egg, granulated sugar, sour cream, cornstarch, and vanilla until smooth and creamy.
- Fold in the crushed Oreos. Set aside 2–3 tablespoons (about 30g) of this mixture for swirling later.
Brown the Butter:
- In a saucepan over medium heat, melt the butter.
- Continue cooking, stirring constantly, until the milk solids at the bottom turn golden brown and the butter smells nutty (about 4–6 minutes).
- Immediately transfer to a heatproof mixing bowl to prevent burning.
Build the Brownie Base:
- To the browned butter, add cocoa powder, chopped chocolate, oil, and vanilla. Stir until smooth.
- Let cool slightly(15–20 minutes).
Whip the Eggs & Sugar:
- In a separate bowl, vigorously whisk the eggs and light brown sugar for 4–6 minutes, until pale and fluffy (this helps create a glossy, crinkled top).
- Add powdered sugar and whisk another 1–2minutes until dissolved.
Combine Wet Ingredients:
- Add the cooled chocolate mixture to the whipped eggs and sugar.
- Stir until fully incorporated.
Add Flour & Chips:
- Fold in flour, salt, and chocolate chips using a spatula.
- Mix just until no streaks remain. Do not over mix.
Layer & Swirl:
- Pour half the brownie batter into the prepared pan and smooth the top.
- Spread the remaining cream cheese mixture evenly over the brownie layer.
- Add the remaining brownie batter on top.
- Dollop the reserved 2–3 tbsp cream cheese mixture and gently swirl with a toothpick or knife.
- Top with extra crushed Oreos for crunch.
Bake:
- Bake for 50–55 minutes, or until the edges are set and the center has just a slight jiggle. Do not over bake, this keeps the center fudgy.
Cool:
- Let cool completely at room temperature, then refrigerate for at least 5–6 hours before slicing for clean edges.

Notes
- Crackly Top Secret: Whipping the eggs and sugar properly, then incorporating warm fat, is key to that glossy crackled brownie top.
- Room Temperature Ingredients are essential for a smooth cheesecake layer.
- Chill Before Cutting: Patience pays off! Cooling fully before slicing helps everything set perfectly.
- You can double the recipe and bake in a 9x13-inch pan for larger batches (adjust bake time accordingly).
