Preheat oven to 350.

Line 2 baking sheets with parchment paper; set aside.

In a large mixing bowl whisk together cake mix and baking powder; set aside.

In a separate bowl, whisk together eggs, oil and vanilla; whisk until combined and mixture is a pale yellow.

Add egg mixture to cake-mix mixture; stir until thoroughly incorporated.

Drop 1-inch rounded balls of dough, two-inches apart, onto previously prepared baking sheets.

Add a few sprinkles on top of each dough-ball and press lightly so they do not roll off. DO NOT flatten cookie-dough balls.

Bake for 9 minutes.

Remove from oven and let stand 2 minutes.

Transfer cookies to a wire rack and cool completely.

Serve
