Step-by-Step Instructions

  1. Preheat the oven:
    Set your oven to 350°F (175°C). Grease or line a 9×9-inch baking pan with parchment paper for easy removal.
  2. Make the brownie batter:
    • In a medium bowl, whisk together melted butter and sugar until smooth.
    • Beat in eggs one at a time, then stir in vanilla.
    • Sift in cocoa powder, flour, salt, and baking powder. Mix until just combined (do not overmix or brownies may turn cakey).
    • Spread the brownie batter evenly in the prepared pan.
  3. Prepare the cookie dough:
    • In a large mixing bowl, cream softened butter with brown sugar and white sugar until fluffy.
    • Beat in egg and vanilla extract.
    • Stir in flour, baking soda, and salt until dough forms.
    • Fold in chocolate chips.
  4. Assemble the brookies:
    Drop spoonfuls of cookie dough over the brownie batter. Lightly spread or press to cover most of the surface (don’t worry if some brownie peeks through – it creates a pretty swirled look).
  5. Bake:
    Place in the oven and bake for 30–35 minutes, or until the cookie top is golden and a toothpick inserted in the center comes out with just a few fudgy crumbs.
  6. Cool and slice:
    Let the brookies cool completely in the pan before slicing into squares. This helps them set for clean, bakery-style cuts.

Pro Tips for Perfect Cookie Brownies

  • Lining the pan: Use parchment paper with overhanging sides for effortless removal.
  • For extra fudgy texture: Slightly underbake by 2 minutes; brownies will firm as they cool.
  • Mix-ins idea: Add chopped walnuts, white chocolate chips, or swirl in peanut butter for a creative twist.
  • Storage: Keep leftovers in an airtight container at room temperature for 3–4 days, or refrigerate for up to a week. They also freeze well for up to 2 months.
