Brownie Layer

  • cup dutch processed cacao powder (40 grams)
  • ½ cup all-purpose flour (60 grams)
  • ½ cup butter, melted and cooled (110 ml)
  • 2 eggs
  • 1 cup chopped chocolate, melted (140 grams)
  • ½ cup granulated sugar or packed light brown sugar (100 grams)
  • 1 tsp baking soda
  • 1 tsp sea salt

Cookie Layer


Brownie Layer

  • Preheat oven to 350 degrees F / 170ºC and line a 9x9 inch (20x20cm) baking pan with parchment paper.
  • In a large mixing bowl whisk the melted butter with sugar until the sugar is dissolved.
  • Add in the eggs and whisk until combined.
  • Pour in the melted chocolate and whisk until combined.
  • Stir in the cacao powder, all-purpose flour and baking soda and mix until just combined.
  • Set aside while making the cookie layer.

Cookie Layer

  • In a bowl add butter and both sugars.
  • Mix until the mixture is light and fluffy, around 5 minutes.
  • Add in the egg and vanilla extract and mix until smooth and creamy.
  • Fold in the flour and baking powder and again mix until combined.
  • Finally, fold in the chocolate chips.


  • In the prepared baking pan pour the brownie batter and spread it into an even layer.
  • Add a spoonful of cookie dough onto a brownie layer. Swirl with a spoon or knife.
  • Bake for 35 minutes until golden brown on top. Note on the baking time: Check these brownies after 15 minutes. If they are done, pull them out of the oven. Depending on your oven / calibration - they may need only 15 minutes and up to 35 minutes to cook through. Don't leave them in too long, or they will get dry!
  • Allow to cool completely before removing from the pan (best overnight).


  • For the cleanest cut lines, make sure to let the brownies cool completely - this will ensure they don't crumble when slicing. Also, try slicing your brownies with a plastic knife for cleaner lines.
  • Make sure to use a high quality unsweetened cocoa powder as opposed to a sweet cocoa mix. 
  • Be careful not to swirl your batters together too much; you want the different flavors to stay distinct.
  • To make sure your brownies have a fudgy texture, whisk together the butter and sugar thoroughly. But do not over mix the brownie batter. It will cause the brownies to be dense and heavy.
  • Use room temperature ingredients when making your cookie dough; it will come together much more easily.
