  • Preheat oven to 350°F (175°C) and grease an 8x8 inch baking pan or line with parchment paper.

  • Prepare the cookie layer: In a separate large bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy. Beat in the egg and vanilla.
  • Whisk together flour, baking soda, and salt. Gradually add to the wet cookie ingredients until just combined. Stir in chocolate chips.
  • Drop spoonfuls of the cookie dough over the brownie batter and gently spread or press down to cover the surface.

  • Allow to cool completely in the pan before slicing into 16 squares.
