Method
 

Preparation
  1. Preheat the oven to 350°F and line baking sheets with parchment paper.
  2. Gather and measure ingredients exactly as specified for both doughs.
Make the Brownie Dough
  1. Cream the room-temperature butter with light brown and granulated sugar until pale and fluffy.
  2. Mix in the egg and vanilla until homogenous.
  3. Sift in Dutch-process cocoa, flour, baking soda, and salt; fold gently until combined.
  4. Stir in the 2/3 cup of semi-sweet chocolate chips last to distribute.
Make the Cookie Dough
  1. Using a mixer, cream the cold cubed butter with light brown and granulated sugar until pale and slightly aerated.
  2. Add the egg and extra yolk with vanilla, then fold in flour, cornstarch, baking soda, and salt until just combined.
  3. Fold in the 1 cup of semi-sweet chocolate chips for even distribution.
Assemble the Brookie Cookies
  1. Scoop equal parts brownie and cookie dough using a medium cookie scoop.
  2. Press each scoop together gently and roll into a compact ball.
  3. Place balls on the lined baking sheet with space to spread.
Bake the Brookie Cookies
  1. Bake the cookies at 350°F for 8–9 minutes until the edges are set but the centers look slightly underbaked.
  2. Remove from oven and optionally sprinkle flaky sea salt while warm.
  3. Let cool on the sheet for several minutes.
Storage
  1. Allow cookies to cool completely before storing.
  2. Store in an airtight container layered with parchment or freeze in freezer-safe bags.

Notes

For added flavor variations, consider incorporating nuts, caramel bits, or espresso powder to enhance the chocolate flavor and texture. Proper cooling and storage techniques will help maintain the ideal texture of Brookie Cookies.
