Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the cake mix, eggs, and vegetable oil.
Add the vanilla extract and mix until incorporated.
Fold in your chosen add-ins until evenly distributed.
Scoop tablespoon-sized portions of dough onto a baking sheet lined with parchment paper.
Bake for 10-12 minutes or until the edges are lightly golden.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack.
Dust with powdered sugar before serving, if desired.
