Ingredients
To make Easy Cake Mix Cookie Bars, you’ll need the following ingredients, each contributing to the deliciousness of this dish:
- 1 box yellow cake mix (15.25 oz): The base of these bars, offering a sweet and tender crumb.
- 2 large eggs: These add moisture and structure, ensuring a soft and chewy texture.
- 0.33 cup vegetable oil: This brings a rich, velvety mouthfeel that balances the sweetness perfectly.
- 1 cup dark chocolate chips: The deep, bold flavor complements the sweetness beautifully.
- 1 cup milk chocolate chips: These lend a creamy sweetness that appeals to all ages.
- 1 cup white chocolate chips: Adding a sweet and buttery contrast, they round out the chocolate experience.
Together, these ingredients create a symphony of flavors that’s truly irresistible.
Step-by-Step Directions Preparation Steps
Preheat the Oven: Start by preheating your oven to 350°F (175°C). This ensures that your cookie bars bake evenly for a perfect golden finish.
Mix the Ingredients: In a large mixing bowl, combine the yellow cake mix, eggs, and vegetable oil. Use a spatula or a hand mixer on low speed to blend them together until fully incorporated. The mixture will be thick, making sure it is well combined.
Add the Chocolate Chips: Gently fold in the dark, milk, and white chocolate chips. The gooey chocolate bits will melt just enough during baking to create pockets of chocolate bliss in every bite.
Prepare the Baking Dish: Grease a 9×13-inch baking pan with non-stick spray or line it with parchment paper for easy removal. This step is crucial to prevent sticking and aid in easy cleanup.
Spread the Batter: Pour the thick batter into the prepared pan, spreading it evenly with a spatula. Make sure the surface is smooth to ensure even baking.
Bake to Perfection: Place the baking pan in the preheated oven and bake for 20-25 minutes. When done, the edges should be golden, and a toothpick inserted into the center should come out with a few moist crumbs, not wet batter.
Cool and Cut: Once baked, remove the pan from the oven and let the cookie bars cool in the pan for about 10 minutes. Then, transfer them to a cooling rack to cool completely before cutting them into squares.
Tips & Tricks
- Add Nuts: For an added crunch, feel free to toss in some chopped nuts, like walnuts or pecans, to the batter.
- Customize Chocolate Types: You can swap out any of the chocolate chips for your favorite types, such as butterscotch or peanut butter chips.
- Use a Cookie Scoop: For uniform bars, consider using a cookie scoop when spreading the batter into the pan.

FAQs
1. Can I use a different flavor of cake mix?
Absolutely! While yellow cake mix provides a classic flavor, you can experiment with chocolate, vanilla, or even funfetti cake mixes for different tastes.
2. What if I don’t have eggs?
You can substitute eggs with unsweetened applesauce, mashed banana, or a flaxseed mixture (1 tablespoon of ground flaxseed mixed with 2.5 tablespoons of water per egg).
3. How do I know when the bars are done?
Check for a golden edge and perform the toothpick test. A few moist crumbs should stick to the toothpick when inserted but never wet batter.
4. Can I make these cookie bars gluten-free?
Yes, use a gluten-free cake mix, and be sure to check that all chocolate chips are marked gluten-free.
5. How do I keep my cookie bars moist?
