Method
Make the brownie layer
- Heat the oven to 350°F.
- Lightly coat a 9x13-inch baking pan with nonstick cooking spray.
- Line the pan with parchment paper, leaving an overhang on two sides.
- Whisk the melted butter and sugar together in a large bowl.
- Whisk in the eggs one at a time, then whisk in the vanilla until smooth.
- Fold in the flour, cocoa powder, and salt just until no dry streaks remain.
Make the cookie layer
- Beat the softened butter, brown sugar, and granulated sugar in a medium bowl until creamy, about 1 to 2 minutes.
- Beat in the egg and vanilla until combined.
- Stir in the flour, baking soda, and salt.
- Fold in the chocolate chips.
Assemble and bake
- Spread the brownie batter evenly in the prepared pan.
- Drop spoonfuls of cookie dough over the top, spacing them to leave a few small gaps.
- Gently flatten each spoonful.
- Bake for 38 to 45 minutes, until the cookie portions are golden and a toothpick inserted into a brownie portion comes out with a few moist crumbs.
- Cool completely in the pan, about 2 hours.
- Lift out using the parchment and cut into squares.
Notes
For neat squares, let the brookies cool completely before lifting and cutting. Store covered in the refrigerator for up to 4 days; freezer-friendly. For a gluten-free variation, use a cup-for-cup gluten-free flour blend.
