In a medium bowl, combine the cake mix, Cool Whip and egg. Stir until well mixed.
Place the powdered sugar in a small bowl. Drop the cookie dough by teaspoons into the powdered sugar and roll the dough to coat.
Place the balls 1 1/2 inches apart on a baking sheet that has been covered with a non-stick baking mat or sprayed with cooking spray.
Bake the cookies for 8-10 minutes. Remove them from the oven when they are set, but before they get too brown.
Remove the cookies from the cookie sheet to a cooling rack and allow them to cool. Makes about 20 cookies (2 1/2" in diameter)

Notes
1 batch makes about 20 cookies.
Because the cake mix has so much flavor, there's no need for extra vanilla extract.
The calories shown are based on the recipe making 20 cookies, with 1 serving being 1 cookie.
