Cake Mix Chocolate Chip Cookie Bars Recipe
These Cake Mix Chocolate Chip Cookie Bars are the ultimate “lazy baker” hack. By using a boxed yellow cake mix as the base, you bypass the measuring of flour, sugar, and leavening agents, resulting in a perfectly soft and chewy bar every time.

Ingredients
Yellow Cake Mix (13.25 oz) – 1 box
Large Eggs – 2
Vegetable Oil – 1/2 cup
Water – 1/3 cup
Semi-sweet Chocolate Chips – 3/4 cup
Extra Chocolate Chips – for topping
Instructions
Preheat your oven to 350°F (175°C). Spray a 9×13-inch baking pan with nonstick cooking spray or line with parchment paper.
In a large mixing bowl, combine the yellow cake mix, eggs, vegetable oil, and water.
Whisk or stir by hand until the batter is smooth and no large lumps of dry cake mix remain.
Gently fold in the 3/4 cup of chocolate chips using a spatula.
Pour the batter into the prepared baking pan, spreading it to the edges with a spatula for an even layer.
Sprinkle the additional chocolate chips over the top for a professional bakery look.
Bake for 24 minutes. The center should still look slightly underdone and a toothpick should come out “barely gooey.”
Remove from the oven and let the bars rest in the pan for 20-30 minutes to set.
Slice into 12 even bars and serve.
Notes
• Do not overbake! These bars continue to set as they cool; pull them out when the edges are golden but the center is soft.
• Use high-quality chocolate chips for the best flavor profile.
• If the batter seems too thin, ensure you didn’t add extra water; brands vary slightly in hydration needs.
