Preheat oven to 375 degrees F. In a small bowl, melt butter and set aside to cool (or place in the refrigerator briefly to do so).
Sift powdered sugar into a shallow dish (I used a pie plate) and mix in the cornstarch. Set aside.
Pour cake mix, the cooled melted butter, and eggs in a large mixing bowl. Mix with a spatula until well blended. A dough will form from this combination.
Use a small scoop to form 1 inch balls of the dough; drop and roll each in the powdered sugar, and place the balls on a baking sheet about 2 inches apart from one another. Bake for about 9-11 minutes, until the dough is fully set.
Transfer cookies to a wire rack to cool. Store in an airtight container to preserve. Enjoy!
