Once you prepare the box mix brownies in the 9x9 pan lined with nonstick foil, bake and cool.

Place half the chopped candies across the top of the cooled brownies.

In a microwave safe bowl, heat the chocolate chip and sweetened condensed milk.

Stir smooth and pour over the candies and brownies. Use an offset spatula to help spread the fudge layer.

Sprinkle on the rest of the candy bars.

Chill until firm and cut into bars.
