Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, melted
  • 1 ½ cups granulated sugar
  • ¾ cup unsweetened cocoa powder
  • 3 large eggs
  • 1 teaspoon vanilla extract
  • ½ teaspoon salt
  • 1 cup all-purpose flour
  • ½ cup semi-sweet chocolate chips (optional)
  • ½ cup (1 stick) unsalted butter, softened
  • ½ cup granulated sugar
  • ¼ cup packed light brown sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour
  • ½ teaspoon baking soda
  • ¼ teaspoon salt
  • 1 cup semi-sweet chocolate chips

Instructions

  1. Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on the sides.
  2. In a large bowl, whisk together the melted butter, 1 ½ cups granulated sugar, and cocoa powder until smooth.
  3. Beat in the 3 large eggs one at a time. Stir in 1 teaspoon vanilla extract and ½ teaspoon salt.
  4. Gradually add 1 cup all-purpose flour, mixing until just combined. Gently fold in the optional ½ cup semi-sweet chocolate chips.
  5. Pour the brownie batter into the prepared baking pan and spread evenly. Set aside.
  6. In a separate medium bowl, cream together the softened butter, ½ cup granulated sugar, and light brown sugar until light and fluffy.
  7. Beat in the 1 large egg and 1 teaspoon vanilla extract until well combined.
  8. In a small bowl, whisk together 1 ½ cups all-purpose flour, ½ teaspoon baking soda, and ¼ teaspoon salt. Gradually add the dry ingredients to the wet, mixing on low speed until just combined.
  9. Stir in the 1 cup of semi-sweet chocolate chips.
  10. Carefully drop spoonfuls of the cookie dough over the brownie batter. Gently spread the cookie dough over the brownie layer.
  11. Bake for 30-35 minutes, or until the cookie layer is golden brown and a toothpick inserted into the brownie layer comes out with moist crumbs.
  12. Remove from oven and let cool completely in the pan on a wire rack before slicing.
  13. Lift from the pan using the parchment paper and slice into squares. Serve and enjoy!

Notes

  • Don’t overmix: Overmixing can lead to tough baked goods. Mix just until ingredients are combined for both layers.
  • Don’t overbake: For fudgy brownies, a slightly underbaked center is ideal.
  • Cool completely: Patience is key! Allow the bars to cool fully before slicing to prevent crumbling.
  • Storage: Store in an airtight container at room temperature for 3-4 days, or freeze for up to 2-3 months.
  • Variations: Experiment with milk chocolate chips, white chocolate chips, or add a sprinkle of flaky sea salt on top before baking.
