In the bowl of a stand mixer, add cake mixes, eggs and oil. Beat 2-3 minutes until cookie dough comes together. (It comes together very easily, and there won't really be much left around the sides of the bowl)
Stir in chocolate chips.
Roll into 1" balls (I used a 1" cookie scoop -- it makes the process even quicker!) and place 12 to a lightly greased cookie sheet. Bake at 350 degrees F for 7-9 minutes, until puffed and dry-looking on top. They will settle down as they cool.

Notes
*Note: If you're using a smaller cake mix, you'll likely want to try reducing the oil. You don't want your cookie dough too sticky.
