  1. Preheat oven to 350°F (175°C) and line an 8x8 inch baking pan with parchment paper, leaving an overhang on the sides.
  2. Whisk melted butter and sugar until combined, then beat in eggs and vanilla until the mixture is glossy.
  3. Sift in cocoa powder, flour, and salt; fold gently with a spatula until no streaks of flour remain.
  4. Spread the brownie batter evenly into the bottom of the prepared pan.
  5. In a separate bowl, cream the softened butter, brown sugar, and white sugar until light and fluffy.
  6. Mix in the egg and vanilla extract until smooth.
  7. Gradually add flour, baking soda, and salt, then fold in the chocolate chips.
  8. Scoop the cookie dough into small dollops and drop them across the top of the brownie batter, pressing down slightly.
  9. Bake on the center rack for 30–35 minutes until cookie peaks are golden brown and the center has a slight wobble.
  10. Remove from oven and let cool completely in the pan for at least 30 minutes before slicing.
