Peanut Butter Brookies (Cookie Brownies)

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 (½ cup) Granulated Sugar

For the Peanut Butter Cookie Dough

  • 113 g (½ cups) Unsalted Butter Melted
  • 125 g (½ cups) Creamy Peanut Butter
  • 100 g (½ cups) Light Brown Soft Sugar
  • 100 g (½ cups) Granulated Sugar
  • 2 Large Eggs
  • 125 g (1 cups) All Purpose Flour (Plain Flour)
  • 1 tsp Baking Powder
  • 125 g (⅔ cups) Chocolate Chips

Instructions

For the Brownie Batter

  • Pre-heat your oven to 370℉/180℃. Line an 8x8" baking pan.
  • 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. 
  • 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.
  • Now, add the melted chocolate slowly and combine. 
  • 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

  • In a large bowl, whisk together the butter, peanut butter and both sugars until fully combined. Add the eggs and whisk again.
  • Fold in the flour, baking powder and chocolate chips.
  • 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).
  • Bake for about 40-45 minutes, until no longer wobbly in the middle. Remove and let cool before slicing and serving!
