To get started, preheat your oven to 375°F and line a baking sheet with parchment paper
In a large mixing bowl, beat together the cake mix, butter, eggs, and vanilla extract until a soft dough forms.
The dough may be a little sticky, so you may want to chill it in the refrigerator for about 30 minutes before rolling it into balls.
Once the dough is chilled and easy to handle, roll it into 1-inch balls and roll each ball in powdered sugar.
Place the balls on the prepared baking sheet, spacing them about 2 inches apart. Bake the cookies for 10-1 minutes, or until they're set and lightly golden around the edges.
