Easy Brookies (Brownie Chocolate Chip Cookie Bars)

0 Preheat oven to 325°F . Line a 9x9 metal pan with parchment paper, leaving an overhang on the sides for easy removal
1 Prepare the Ghirardelli brownie mix according to the box instructions. Set aside.
2 In a medium bowl, cream together softened butter and both sugars until light and fluffy (about 2 minutes). Beat in egg and vanilla.Add flour, baking soda, and salt and mix until just combined. Fold in chocolate chips.
3 Pour and spread the brownie batter evenly into the prepared pan. Dollop the cookie dough over the brownie layer in small scoops (like a patchwork quilt), then gently spread and flatten with your fingers or an offset spatula to cover most of the surface. It’s okay if a bit of brownie peeks through—it’ll swirl in the oven!
4 Bake for 35–40 minutes or until the cookie top is golden brown and a toothpick inserted in the center comes out with a few moist crumbs. If the top starts to brown too quickly, loosely tent with foil around the 30-minute mark.
