Method
 

Prepare the pan
  1. Heat the oven to 350°F.
  2. Spray a 9x13-inch baking pan with cooking spray.
Make the brownie layer
  1. Whisk the melted 1/2 cup unsalted butter with 1 cup granulated sugar.
  2. Whisk in 2 eggs and 1 teaspoon vanilla extract.
  3. Fold in the cocoa powder, 1/2 cup flour, and 1/4 teaspoon salt until no dry streaks remain.
  4. Spread the brownie batter evenly in the pan.
Make the cookie layer
  1. Beat the softened 1/2 cup unsalted butter with the packed brown sugar and remaining 1/4 cup granulated sugar until creamy.
  2. Beat in the remaining egg and 1 teaspoon vanilla extract.
  3. Mix in the remaining 1 1/4 cups flour and 1/2 teaspoon salt with the baking soda.
  4. Fold in the chocolate chips.
Assemble and bake
  1. Drop spoonfuls of cookie dough over the brownie batter, leaving some brownie batter visible between them.
  2. Bake for 32 to 38 minutes, until the cookie dough is golden around the edges and a toothpick inserted into an exposed brownie area near the center comes out with a few moist crumbs.
  3. Cool completely in the pan, about 1 hour, before cutting.

Notes

For neat slices, cool the brownies completely before cutting. Store covered in the refrigerator for up to 4 days; freezer: yes, freeze tightly wrapped bars for up to 2 months. For a gluten-free variation, use a cup-for-cup gluten-free baking flour blend.
