The perfect blend of two iconic American treats, these Oreo Brownies will become your new favourite dessert! With a classic chocolate brownie batter and full-sized Oreos in every bite, how could it not?
Put the dark chocolate and butter in a large microwave safe bowl. Microwave in 30 second bursts, stirring between each burst, until melted. Avoid overcooking as this can negatively affect the chocolate.
Add the caster sugar. Stir through with a manual whisk - I say stir as you don’t want to add air but a whisk is still the best tool as it distributes everything quickly.
Add the eggs and vanilla. Stir with the whisk again.
Put the flour through a sieve into the bowl. Stir to combine.
Assemble the brownie
Pour half of the brownie batter into your prepared tin and level off.
Place the cookies and cream spread in a bowl and microwave for 15-30 seconds until loosened.
Drizzle half the spread over the brownie batter.
Top with three quarters of the Oreo cookies (reserve 8 cookies or 60g).
Pour the remaining brownie batter on top and level off.
Drizzle with the remaining spread and swirl a little with the handle end of a spoon.
Top with the remaining broken Oreo cookies.
Bake for 30 minutes. You can test if it's baked by pushing a skewer into the centre. If just right, you'll see sticky crumbs.
Place the brownie in its tin on a wire rack to cool completely. I like to then chill mine overnight to get them nice and firm for slicing.
Once completely cooled, transfer the brownie to a board and trim the edges, then cut into 12 equally sized squares in a 3x4 pattern.
