Instructions

For Chocolate Chip Cookie Layer:

  • Preheat oven to 350 degrees (F). Spray an 8x8 pan with non-stick spray and line with parchment paper, leave an overhang to make it easy to remove the baked brookies.
  • In a large bowl using a hand mixer or in the bowl of a stand mixer cream together the butter, granulated sugar, and brown sugar until light and fluffy.
  • Add the eggs one at a time, mixing fully before adding the next. Add the vanilla and combine.
  • In a medium bowl combine the flour, baking soda, baking powder, and salt. Whisk to combine.
  • Add the dry ingredients to the wet ingredients. Mix until just combined.
  • Fold in the chocolate.
  • Break chunks of cookie dough off and place them in the bottom of the pan. The chunks should be about ½ to 1 inch. Repeat until there are only small gaps without cookie dough.
  • Allow the dough to chill while you make the brownie batter.

For Brownie Batter:

  • In a medium bowl mix with a hand mixer combine the melted butter and brown sugar. When fully combined add the eggs and vanilla. Beat until fully combined and light in color.
  • In a small bowl combine the flour, cocoa powder, and salt. Whisk to combine and remove any lumps.
  • Add the dry ingredients to the wet ingredients and mix until just combined.
  • Fold the chocolate into the batter.
  • Pour the brownie batter over the cookie dough.

For Marshmallow Layer:

  • Sprinkle the mini marshmallows over the top until most of the brownie batter is covered.
  • Bake for 35-40 minutes until a toothpick inserted in the center comes out with only a few moist crumbs.
  • Allow to cool completely. Lift brookies from pan and cut into 16 squares
