These Brownie Mix Cookies are rich chewy cookies with a crisp outside and are made from just 4 ingredients!


  • One 18.9 oz box Triple Chunk Brownie Mix
  • 1 cup all purpose flour
  • 2 eggs (beaten)
  • 2 tablespoons water *See notes.
  • 1/2 cup unsalted butter (melted and cooled or 1/2 cup vegetable oil)

  1. In a large bowl, stir together the dry brownie mix and all purpose flour.
  2. Add the beaten eggs, water and butter (or oil).
  3. Stir until thoroughly combined.
  4. If you are using a plain brownie mix and want to add nuts or chips, stir in 1/2 cup to the dough.
  5. Refrigerate the cookie dough for at least an hour or up to 24 hours.
