Peanut Butter Brookies (Cookie Brownies)

These bring together all that is good about a fudgy brownie and a peanut butter cookie. The two mixtures are made separately before swirling together to create a marbling effect! The result is a rich chocolate brownie with generous bites of peanut butter cookie!

  • 100 g Light Brown Soft Sugar

For the Peanut Butter Cookie Dough
  • 113 g Unsalted Butter Melted
  • 125 g Creamy Peanut Butter
  • 100 g Light Brown Soft Sugar
  • 100 g Granulated Sugar
  • 2 Large Eggs
  • 125 g All Purpose Flour (Plain Flour)
  • 1 tsp Baking Powder
  • 125 g Chocolate Chips

Method
 

For the Brownie Batter
  1. Pre-heat your oven to 370℉/180℃. Line an 8x8" baking pan.
  2. In a small bowl, break up the dark chocolate and melt in the microwave in 20 second intervals, stirring in between to make sure it doesn't burn. Alternatively, set up a double boiler. Do this by placing a heatproof bowl over a small pot of simmering water. Add the chocolate to the heatproof bowl and stir until melted. 
  3. In a large mixing bowl, whisk together melted butter and both sugars until fully combined (3-5 minutes). Add in the eggs and vanilla and whisk again.
  4. Now, add the melted chocolate slowly and combine. 
  5. Add the flour, salt and cocoa powder. Fold gently with a rubber spatula or wooden spoon until just combined. Set aside.
For the Peanut Butter Cookie Dough
  1. In a large bowl, whisk together the butter, peanut butter and both sugars until fully combined. Add the eggs and whisk again.
  2. Fold in the flour, baking powder and chocolate chips.
  3. In the lined pan, alternate between adding the brownie batter and cookie dough. Add a few scoops of each at a time, so they are randomly dotted around the pan, with brownie touching cookie. Use a knife to swirl just a little (we don't want to mix everything).
  4. Bake for about 40-45 minutes, until no longer wobbly in the middle. Remove and let cool before slicing and serving!
