Preheat oven to 350ºF. Prepare the sugar cookie mix according to package directions. Roll the dough into 1-inch balls and place into a mini muffin tin. Bake for 9-11 minutes and allow to cool for 2 minutes.
Use the bottom of a shot glass or wine bottle cork to make a well in the center of each cookie. Add a teaspoon of Nutella into each well and finish with sprinkles on top. Let the cookie cups cool in the pan for another 20 minutes before removing them.
