Instructions

  1. Preheat your oven to 350℉. Spray a 9×13 metal pan with nonstick spray and line with parchment paper.

  4. Press half of the dough into the prepared pan and set aside the rest.

  6. Stir in semi-sweet chocolate until melted, then whisk in the vegetable oil and cocoa powder.
  7. Mix in the eggs, egg yolk, and granulated sugar until dissolved, then add the dry ingredients and fold in chocolate chips.
  8. Spread slightly more than half the brownie batter in the pan and layer the cookie dough on top.
  9. Bake for 38 to 44 minutes until the cookie layer is golden.
  10. Cool in the pan for 1-2 hours before slicing and serving.
