Preheat the oven to 350 degrees F. Spray a 9×13 baking pan with nonstick cooking spray and set aside.
Nonstick Spray
In a large mixing bowl, combine the cake mix, eggs, water and oil. Stir the mixture until no lumps appear. Don’t over mix or this will make the bars dry.
1 box yellow cake mix, 2 large eggs, 1/2 cup vegetable oil, 1/3 cup water
Fold in the chocolate chips.
1 cup semi sweet chocolate chips
Spoon the batter into the prepared pan and spread evenly. If desired sprinkle some additional chocolate chips over the top.
Bake for 20-24 minutes or until a toothpick inserted into the center comes out just barely gooey and the top is light golden brown.
Let the bars cool in the pan for 20-30 minutes. Once cool, slice the bars, serve, and enjoy!
