Preheat oven to 350°F and line a cookie sheet with parchment paper or silicone baking mat.
Combine cake mix, eggs, and oil and mix until dough forms.
Stir in Andes mint pieces.
Portion out balls of dough that are 1 1/2 inch to 2 inches in size.
Place cookie balls on baking sheet, about 2-3" apart.
Bake at 350 for 8-10 minutes, until cookies puff up and cracks form in the surface.
Remove from oven and immediately place one unwrapped Andes chocolate mint on top of each cookie.
Wait a couple minutes so that the hot cookies start to melt the chocolates. Use an offset spatula or butter knife to spread the chocolate on top of the cookies.
Allow cookies to cool so chocolate sets.
