Creating delicious cookie bars using a box of yellow cake mix is a simple yet ingenious way to whip up a tasty treat with minimal effort. This recipe transforms a basic cake mix into a delightful dessert that’s both versatile and satisfying. Whether you’re in need of a quick snack for a family gathering or looking for an easy bake sale item, these cookie bars are sure to impress. Here’s how to make them.


1 box of yellow cake mix
1/2 cup (1 stick) of unsalted butter, melted
2 large eggs
1 teaspoon of vanilla extract
1/2 cup of semi-sweet chocolate chips
1/2 cup of chopped nuts (optional)
1/4 cup of any add-ins you like (such as M&M’s, peanut butter chips, white chocolate chips, etc.)


  1. Preheat and Prepare
    Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper. This makes for easy removal and clean-up.
  2. Mix the Batter
    In a large mixing bowl, combine the yellow cake mix, melted butter, eggs, and vanilla extract. Stir until well mixed. The batter will be thick, resembling cookie dough more than cake batter.
  3. Add the Fun Stuff
    Fold in the chocolate chips, nuts (if using), and any other add-ins you desire. The beauty of this recipe lies in its versatility, so feel free to get creative with your mix-ins!
  4. Spread in Pan
    Transfer the mixture to the prepared baking pan. Using a spatula or your hands, press the dough evenly into the pan. It might be sticky, so lightly flouring your hands or using a piece of wax paper can help with spreading.
  5. Bake
    Bake in the preheated oven for 20-25 minutes or until the edges are golden brown and a toothpick inserted into the center comes out clean. Be careful not to overbake, as the bars will continue to set as they cool, ensuring a soft, chewy texture.
  6. Cool and Cut
    Allow the bars to cool in the pan on a wire rack for at least 30 minutes. Once cooled, cut into squares or bars of your desired size.

Tips and Variations:

Customize Your Bars: The simplicity of this recipe makes it perfect for customization. Experiment with different mix-ins and toppings like coconut flakes, dried fruit, or a drizzle of caramel or chocolate sauce after baking.

Make It Festive: Tailor the cookie bars to fit any occasion by choosing themed add-ins, such as red and green M&M’s for Christmas or pastel-colored sprinkles for Easter.

Texture and Flavor: For a richer flavor, brown the butter before mixing it with the cake mix. This adds a nutty depth to the bars that’s irresistible.

Yellow cake mix cookie bars are not just easy to make but also incredibly adaptable to what you have on hand. They’re a fantastic way to make something special out of pantry staples, and the end result is a batch of mouth-watering treats that everyone will love. Whether you stick to the basics or get inventive with your ingredients, these cookie bars are a guaranteed hit for any occasion.

Serving and Storing:


These cookie bars are best served at room temperature. If you’ve added chocolate chips or other melty ingredients, waiting until they’re fully cooled allows these components to set, resulting in the perfect chewy texture with a slight crunch. For an extra indulgent treat, serve with a scoop of vanilla ice cream on top or a dollop of whipped cream.


Store leftover cookie bars in an airtight container at room temperature for up to 5 days. For longer storage, you can freeze the bars for up to 3 months. To do so, wrap each bar individually in plastic wrap and then place them in a freezer-safe bag or container. Thaw at room temperature or in the microwave for a quick snack.

Healthier Options:

For those looking for a lighter version of this recipe, consider making the following substitutions:

Butter: Use unsweetened applesauce or a butter substitute to reduce fat content.

Eggs: Try a flaxseed or chia seed egg substitute for a vegan option.

Add-ins: Incorporate nuts and dried fruit for added nutrients. Dark chocolate chips can be a healthier alternative to milk or white chocolate.

Gluten-Free Adaptation:

To make gluten-free cookie bars, use a gluten-free yellow cake mix and ensure that all your add-ins are also gluten-free. This simple substitution allows you to cater to dietary restrictions without compromising on taste.

Fun with Frosting:

For an extra layer of flavor, consider adding frosting to your cookie bars once they have completely cooled. A simple vanilla or chocolate buttercream, cream cheese frosting, or even a peanut butter frosting can elevate your cookie bars to the next level. Spread a thin layer over the top and let it set before cutting into bars.

The Magic of Cake Mix:

This recipe exemplifies the versatility of cake mix as a baking shortcut. Beyond cookie bars, you can use cake mix to create a variety of desserts, from cupcakes and cookies to trifles and even quick bread. The key is to view the cake mix as a base and let your creativity dictate the variations.

Yellow cake mix cookie bars stand out for their ease of preparation, delicious taste, and adaptability.

Whether you’re a novice baker or looking for a quick dessert solution, this recipe is a foolproof choice that’s bound to become a staple in your baking repertoire. With endless possibilities for customization, you can enjoy a new version every time you bake them. So, grab that box of cake mix and let your culinary creativity shine!

Sugar Content: These bars are high in sugar due to the cake mix and added chocolate chips or candies. For a lower sugar version, look for reduced-sugar cake mixes or cut down on the amount of sweet add-ins.

Fat Content: The fat content is primarily from the butter and eggs. Using unsweetened applesauce in place of butter and egg substitutes can lower this significantly.

Making Healthier Choices:

When indulging in desserts like these cookie bars, it’s all about balance. Enjoying them as an occasional treat within the context of a balanced diet is key. Pairing a small serving with a healthy serving of fruit, for example, can add nutritional value to your snack. Additionally, being mindful of portion sizes helps manage calorie intake while still allowing you to enjoy these delicious treats.

To further tailor this recipe to fit a healthier dietary pattern, consider experimenting with substitutions that reduce the sugar, fat, and calorie content without sacrificing flavor. For example, replacing some of the butter with Greek yogurt can maintain moisture while cutting fat, and using a sugar substitute or reducing the amount of mix-ins can lower sugar content.

Remember, the joy of baking at home is the ability to control the ingredients to suit your taste and health preferences. Enjoy the process and the delicious results!
