Preparation
- Preheat your oven to 400°F (204°C).
- Line two baking sheets with parchment paper and set them aside.
- In a stand mixer, combine the cold butter, brown sugar, and granulated sugar. Beat until creamy and no visible chunks of butter remain (2-3 minutes).
- Add the egg and egg yolk; mix until fully incorporated. Then add the vanilla extract.
- In a separate bowl, whisk together the flour, cocoa powder, salt, baking powder, and baking soda.
- Gradually add the flour mixture to the wet ingredients, mixing just until combined.
- Fold in the semi-sweet chocolate chunks, milk chocolate chips, and white chocolate chips.
- Shape the dough into 8 large balls, spacing them evenly on the baking sheets.
- Bake for 12-13 minutes until edges are set and tops have slight cracks.
- Let the cookies cool on the baking sheet for 10 minutes before transferring to a wire rack.
Notes
These cookies can be stored in an airtight container at room temperature for up to a week, or frozen in a zip-top bag for up to 3 months. Prepare the dough ahead and refrigerate for optimal results.
