Preheat your oven to 350°F (175°C).
Line your 9x13 inch baking pan with parchment paper.
Press the refrigerated chocolate chip cookie dough evenly into the bottom of the prepared baking pan.
Coarsely chop 8 of the Mint Oreos and sprinkle them over the cookie dough layer.
Sprinkle half of the chocolate chunks (1/2 cup) over the Oreos.
In a microwave-safe bowl, combine the sweetened condensed milk with the coarsely chopped Andes Mints. Microwave until melted and smooth, then pour over the chocolate chunks and Oreos.
Sprinkle the remaining chocolate chunks and chopped Mint Oreos over the melted Andes mixture, then pour sweetened condensed milk over the top.
Bake for about 25-30 minutes, or until the top is bubbly and lightly golden.
Once baked, let it cool completely in the pan before cutting into squares or rectangles.
