Preheat oven to 350 degrees.
In a bowl, using a hand mixer, cream together the butter and sugar for 1 minute.
Scrape the sides of the bowl, add the eggs and vanilla. Mix until combined.
Add in the cake mix and the flour. Mix until the dough comes together and the ingredients are thoroughly incorporated. Add in the extra sprinkles, if desired.
Scoop the dough into balls and arrange on the cookie sheet. I love making these small by using my 2 tsp scoop for each cookie.
Bake at 350 degrees for 8 minutes.
Allow to cool on the pan for 3-5 minutes before transferring to a wire cooling rack.
Enjoy!
