In the bowl of an electric mixer fitted with the paddle attachment, beat both sugars, butter, vanilla, and eggs until smooth. Beat in melted baking chocolate and cocoa powder. Beat in flour and baking soda until well blended. Stir in all the chocolate chips and mint pieces.

Chill dough for at least 1 hour. You can also chill it for about 30 minutes, then scoop balls of dough on the cookie sheets and chill those for about 10 minutes and you’ll net the same result as chilling the bowl of dough for an hour.

Preheat oven to 350F. Line cookie sheets with parchment or a silpat. Drop cookie dough balls (I used a 2 tablespoon cookie scoop) onto your cookie sheet, about 2 inches apart. Sprinkle a few more Andes Baking Chips on top of each cookie and press to adhere. This is optional, but it makes the cookie look prettier!

Bake for 9-11 minutes, until the edges lose their sheen. I like these a little under-done, so I take them out when the center is still a tiny bit shiny.

Cool 5 minutes on the cookie sheet, then move to a rack to cool completely. They'll last a few days in a sealed container, but you can also freeze them in ziploc bags. Be sure to layer paper towels between cookie layers and seal, then freeze for up to one month. Defrost at room temperature or in the refrigerator, leaving the paper towels in to absorb the moisture.
