Instructions

  • Preheat the oven to 350°F (180°C). Spray a 9x13 baking pan with nonstick cooking spray and set aside.
  • In a large mixing bowl, combine all the ingredients except the chocolate chips and mix until no lumps appear.
    1 box yellow cake mix, 2 large eggs, ½ cup vegetable oil, ⅓ cup water
  • Fold in the ¾ cup chocolate chips.
    ¾ cup chocolate chips
  • Pour the batter into the prepared pan and spread evenly.
  • Sprinkle a few chocolate chips over the top and bake for 24 minutes or until a toothpick inserted into the center comes out just barely gooey. You don't’ want them to be 100% finished as they will continue to cook once pulled out of the oven.
  • When the toothpick comes back just barely gooey, pull the pan from the oven and let the bars rest in the pan for 20-30 minutes. If sliced before they’ve cooled a bit, they will tend to fall apart.
  • Once cool, slice the bars, serve, and enjoy!

Notes

  • Check Your Cake Mix Size: Ensure your cake mix is 13.25 ounces. This recipe works best with this size.
  • Avoid Too Many Chocolate Chips: Adding too many chocolate chips can make the bars fall apart, even after resting. They’ll be gooey and delicious, but a bit messy!
  • Fold in the Chocolate Chips: Use a rubber spatula to gently fold in the chocolate chips. This keeps the batter light and fluffy.
  • Spread the Batter Evenly: This ensures that your bars bake uniformly. No one wants one side too crispy and the other too soft!
  • Toothpick Test: Don’t wait for the toothpick to come out clean. Slightly gooey means they’re just right. They’ll firm up as they cool, staying deliciously soft.
  • Bake in a Smaller Pan: If using a smaller pan, lower the oven temperature to 325°F and bake a bit longer. This will result in thicker bars.
  • Cool Completely: Patience is key here. Letting the bars cool in the pan helps them set properly, making them easier to slice without falling apart.
  • Extra Chocolate Chips: For an extra touch of chocolatey goodness, sprinkle some extra chocolate chips on top before baking. It’s the little things that make these bars irresistible.
  • Embrace the Softness: These bars will be softer than cookies, which is part of their charm. Enjoy the unique texture!
