I know you want one =).  When I first began to create the recipe for this cookie I started with a chocolate cookie dough made from scratch.  I hated the taste the cocoa left behind, or something.   So, after 2 previous failed attempts at the perfect chocolate cookie (and lots of cookie dough tossed in the trash),  I now have the perfect chocolate cookie.  This recipe starts with a brownie mix and they are amazing to say the least!  If you like chocolate or brownies you will love this cookie (and I mean come on who doesn’t like chocolate and brownies? =).  It even reminds me of those amazing chocolate covered marshmallows that I love.  This recipe is a must try!  These cookies are luxurious!

  • Preheat oven to 350 degrees. Butter a cookie sheet and set aside. In a large mixing bowl, whisk together brownie mix, flour, brown sugar and salt. Add in eggs and milk and stir with a large spoon. Add in melted butter and vanilla and stir until well blended. 
  • Spoon dough by heaping tablespoonfuls onto greased cookie sheet (you can fit 12 per sheet). Bake for 9 minutes and remove from oven and top each cookie with about 6 - 7 marshmallows (you may have to push down on the marshmallows slightly to keep them from rolling off). 
  • Move oven rack near the top of the oven and return cookies to oven to bake 2 more minutes until marshmallows soften. Remove from oven and set cookies aside. In a small microwave safe mixing bowl combine chocolate chips, butter and water. 
  • Microwave chocolate on 50% in 30 intervals stirring after each interval until melted and smooth. Pour mixture into a small ziploc bag. Cut a small tip off the end and drizzle over marshmallow brownies cookies. Store cookies in an airtight container.
