Cookie dough

  • 125 g (½ cups) unsalted butter (room temperature)
  • 100 g (½ cups) light brown soft sugar
  • 125 g ( cups) caster sugar (golden or white)
  • 1 egg
  • 1 teaspoon vanilla extract
  • 225 g ( cups) plain flour
  • ¼ teaspoon salt
  • 200 g (¾ cups) chocolate chips (milk, white or a mix)


  • 125 g (½ cups) unsalted butter
  • 125 g (¾ cups) dark chocolate
  • 185 g (¾ cups) golden caster sugar
  • 2 eggs
  • 60 g (½ cups) plain flour
  • 30 g ( cups) cocoa powder
  • 70 g ( cups) chocolate chips (optional, milk, white or a mix)

Oreo layer

  • packs oreos (roughly 375g)


Cookie Dough:

  • Pre-heat oven: 160°C (fan) / 180°C / Gas Mark 4 / 350 F
  • Cream together the butter and sugars until fully combined.
  • Add in the egg and vanilla, beating the mix until smooth.
  • Sift in the flour and salt, stirring together until just combined.
  • Mix in the chocolate chips.
  • Pop your cookie dough into the fridge while you make the brownie mix.


  • Melt the butter and dark chocolate, either in the microwave (no more than 30secs at a time) or over a double boiler, stirring until completely melted and smooth.
  • Using an electric mixer, whisk the eggs and sugar. This should whip up to being thick and creamy like a milkshake, and can take roughly 3-8mins.
  • Pour the cooled chocolate mix over the fluffy eggy mix, then gently fold together with a spatula or wooden spoon.
  • Sieve and fold the plain flour and cocoa powder into the eggy chocolate mix, until just combined.
  • Stir in the chocolate chips (if using) until they’re dotted throughout.


  • Line a 9in x 13in baking tin with grease-proof paper. Squish the cookie dough down into the bottom of the tin firmly, either using your hands or the back of a large spoon. You want a thin and even layer across the base of the tin.
  • Layer the Oreos on top - as many as you can fit with no overlaps and leaving a half inch of space at the edges.
  • Pour the brownie mix over the Oreo layer, covering them completely and smoothing over top.
  • Bake for 35 - 40mins. Once it's cooked, a skewer should come out clean from the brownie layer and the surface should be lightly cracked and papery. The brownies shouldn’t wobble like a liquid once cooked.
  • Allow to cool completely and then cut into squares.
