Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the chocolate fudge cake mix and baking powder. Stir until well combined.
Add the eggs, oil, milk, and vanilla extract to the dry mixture. Mix until just combined, being careful not to overmix.
Gently fold in 1 cup of the chocolate candies. Reserve the rest for topping.
Using a cookie scoop or spoon, drop rounded tablespoons of dough onto a lined baking sheet, leaving about 2 inches of space.
Press a few extra chocolate candies into the tops of each cookie dough mound.
Bake for 10-12 minutes until edges are set and centers are still soft.
Allow cookies to cool on the baking sheet for about 5 minutes before transferring to a wire rack to cool completely.
