Preheat your oven to 350°F (175°C).

In a large mixing bowl, combine the cake mix, thawed Cool Whip, and egg. Stir until a soft, sticky dough forms.

Using a spoon or a cookie scoop, drop dough balls onto a lined baking sheet, leaving space for spreading.

Roll the dough balls in powdered sugar if desired.

Bake for about 10-12 minutes, or until the edges are golden and the centers are set.

Let them cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely.
