Preheat the oven to 350 degrees F and line cookie sheets with parchment paper or a silicone baking mat.
Put the powdered sugar on a plate. Use a cookie scoop or spoon to make the dough into 1-inch balls. Roll the cookie balls in the powdered sugar until they are completely covered.
1/2 cup powdered sugar
Place the balls on the prepared baking sheet about 2 inches apart. Bake at 350 degrees F for 10-12 minutes, until they look cooked in the middle.
Let the baked cookies cool on the baking sheet for 5 minutes. Then remove to a wire rack to finish cooling.
Chiling isn't absolutely necessary, but it will make the dough significantly easier to handle.If you don't have parchment paper or a silicone mat, spray the baking sheets with non-stick cooking spray.You can modify the recipe to use another variety of cake mix or roll the dough balls in sprinkles or sparkling sugar.
