Preheat your oven to 375. Spray a 9 by 13 pan with cooking spray and set aside.
Mix the cookie mix and press it into the bottom of the pan.
Top the cookie dough with the Milky Way bars and the chocolate chips. Then pour the sweetened condensed milk evenly over the bars.
Bake for 25 to 28 minutes or until the whole top is a golden brown.
Let cool. Cut into them and enjoy!
