Beat together eggs and cool whip until creamy, then beat in the dry cake mix until fully incorporated.
Cover and pop in the fridge for 30 minutes so the dough can stiffen.
Preheat oven to 350 degrees F and line a baking sheet with parchment paper and set aside.
Once the dough has chilled, use a medium cookie scoop to measure out even amounts of dough. Roll the balls of dough in your hands then roll them in powdered sugar and place balls of dough 3 inches apart on the baking sheet.
Bake for 9-11 minutes and allow to cool on the pan for a couple of minutes before transferring to a baking sheet to cool completely.
Notes
Cookies may look slightly underdone in the center after the 10-ish minutes are up, this is normal. Remove them from the oven and allow them to firm up on the cookie sheet before transferring to a cooling rack to cool completely.
