Preheat your oven to 160C/350F and line a baking tin with greaseproof paper.
Place the butter and sugar in a double boiler on medium heat until the butter is beginning to melt.
Whisk to combine and help the sugar and butter mix evenly, continue whisking to help dissolve the sugar for at least 1 minute.
Remove from the heat and allow to cool for 2 minutes.
Add in one egg and whisk until well combined, repeat with the remaining egg until the mixture is smooth.
Whisk in flour, salt and cocoa powder until the brownie batter is combined and smooth.
Oreo cheesecake
Meanwhile, beat the cream cheese on medium with an electric beat until smooth, approximately 1 minute.
Add in the sugar and beat until well combined.
Toss in the Oreo’s and stir to combine.
Pour ⅔’s of the brownie into your prepared tin.
Pour half the cheesecake over the top and spoon the remaining brownie batter and pour in the remaining cheesecake mixture.
Smooth out and swirl with a skewer.
Press the roughly broken Oreos onto the top and place in the oven to bake until no longer jiggly, approximately 45 minutes.
Remove and allow to cool to room temperature before transferring to the fridge for 30 minutes.

Notes
Brown sugar: The brown sugar helps to make the brownies fudgy, however, you could substitute in equal measure with superfine or caster sugar which will result in a chewier final brownie.
Using any type of Oreos in this: Whether it's classic Oreos, Double Stuffed, or even flavored options, the choice is yours!
Cream cheese: The core of our creamy cheesecake layer is room temperature full fat cream cheese, this helps give us a light cheesecake that is easy to mix until smooth.
Substituting the cream cheese: While it's not recommended to substitute entirely, you can try using a different type of soft cheese, such as mascarpone or Neufchâtel cheese, to achieve a similar texture and flavor.
Square tin: A 18×18 cm or 7×7 inch square baking tin works well here, though a rectangle tin would also work well.
Making them ahead: You can store Oreo Cheesecake Brownies in an airtight container in the refrigerator for up to 6 days.
Freezing the brownies: Once they have cooled completely, wrap them tightly or place them in a freezer-safe container. They can be stored in the freezer for up to 2-3 months.
