Instructions
 

Make the brownie

  • Preheat your oven to 350°F (176°C).
  • With your stand mixer (or hand mixer) cream the softened butter and sugars until it resembles a wet sand texture.
    3/4 cup softened butter, 2/3 cups granulated sugar, 1/3 cup brown sugar
  • Add the eggs and vanilla extract and mix until fluffy and lighter in colour.
    1 tsp vanilla extract, 2 eggs
  • Add the sourdough discard but switch to using a spatula and not your mixer anymore. This will insure a light dough. Mix with the spatula until well combined.
    1/3 cup sourdough discard
  • Mix in the cacao powder.
    1/2 cup cacao powder (unsweetened)
  • Start incorporating the flour, baking soda, and salt. Mix until well incorporated.
    1 cup all-purpose flour, 1/2 tsp baking soda (bicarbonate of soda), a pinch of salt
  • The brownie dough should be thick but soft.
  • Line your baking pan (preferably metal) with parchment paper. I used a 10'' x 8''.
  • Put the dough in the pan and spread it evenly with the spatula.

Make the cookie dough

    1 egg, 1 tsp vanilla extract
  • Add the sourdough discard but switch to using a spatula and not your mixer anymore. Mix with the spatula until well combined.
    1/3 cup sourdough discard

    1 1/4 cup all-purpose flour, 1/2 tsp baking soda (bicarbonate of soda), a pinch of salt
  • Add the chocolate chips and fold them into the dough with your spatula.
    1 cup chocolate chip cookies (milk or dark)
  • As with the brownie dough, the cookie dough should be thick but soft.
  • Layer the cookie dough on top of your brownie with your spatula.
  • Bake the brookie for 30 to 40 minutes at 350°F (176°C). The centre of the cake should be set but not completely firm. The top should have a nice golden brown crust.
  • Optional step: 5 minutes before finishing baking, sprinkle a few small chunks of chocolate for extra crunch and chocolatey delight.

  • Let the brownie cool off completely before slicing.
  • Slice it into your desired size bars.
  • Serve plain or with a scoop of vanilla ice cream.

Notes

Note: I recommend using a metal baking pan for best result. If you choose a glass or ceramic baking pan, it might take longer to bake.
