Preheat the oven to 350°F/180°C (160°C fan oven), and lightly grease a 9×13" baking pan with baking spray.
In a large bowl, whisk the eggs with oil or melted butter. Add the cake mix, and mix with a spatula until combined. The cookie dough will be stiff but that's okay.
Fold in the chocolate chips then transfer to the baking pan and press it in with the spatula (it will take you a minute, as the cookie dough will be stiff).
Bake for 20-25 minutes or until the edges are light golden brown.
Cool completely in the pan, then remove and cut into 16 bars.
