Preheat your oven to 350 degrees. Line 2 baking sheets with parchment paper.
Whisk together the oil and eggs in a medium size bowl until well combined. Add the dry cake mix and stir with a rubber spatula until no dry streaks remain.
Spray a spoon or scoop with cooking spray. Scoop the cookie dough and drop it on the cookie sheets leaving about 2 inches between each cookie.
Bake for 8-12 minutes. You will know the cookies are done when the middle is set and the edges are just starting to turn slightly brown.
Let the cookies cool for 5 minutes on a the baking sheets before transferring to a cooling rack.
