Ingredients

- Yellow Cake Mix: The star ingredient here! It’s what makes these cookie bars irresistibly soft, sweet, and full of that nostalgic homemade flavor. This shortcut is a game-changer for turning out treats in no time without sacrificing taste.
- Chocolate Chips: These little gems bring the magic. Whether you go for semi-sweet, milk, or dark chocolate, they melt into gooey pockets of sweetness in every bite. Feeling fancy? Try mixing in white chocolate chips or peanut butter chips for a fun twist.
- Eggs: The glue that holds it all together. Eggs provide structure and give the bars that soft, chewy texture that keeps you coming back for more.
- Oil: This is the secret to moist, rich cookie bars that never dry out. Vegetable or canola oil works great in this recipe.
- Water: Just a small amount of water brings everything together. It helps the batter come to the perfect consistency – smooth and ready to bake.
Substitutions and Additions
- Different Cake Mix Flavors: Swap the yellow cake mix for chocolate, vanilla, or even spice cake for a fun twist.
- Mix-Ins: Try adding chopped nuts, white chocolate chips, or even dried fruit for variety.
- Toppings: Sprinkle with flaky sea salt or drizzle with melted chocolate for an extra special touch.
Step by Step Instructions
Preheat Your Oven: Set it to 350°F and prepare a 9×13-inch baking pan by spraying it with nonstick cooking spray.

Mix the Batter: In a large mixing bowl, combine the cake mix, eggs, oil, and water. Stir until smooth and no lumps remain.

Fold in Chocolate Chips: Gently fold in ¾ cup of chocolate chips with a rubber spatula. Avoid overmixing at this stage.

Spread and Top: Pour the batter into the prepared pan, spreading it evenly. Sprinkle additional chocolate chips over the top.
Bake: Bake for 24 minutes, or until a toothpick inserted into the center comes out just slightly gooey. They won’t quite be 100% finished and will continue to cook once removed from the oven.

Let It Rest: Allow the bars to cool in the pan for 20–30 minutes before slicing to let them set (otherwise, they may fall apart).
Slice and Enjoy: Once cooled, slice the bars and enjoy the decadent chocolate flavor of these delicious cookie bars.
Tips and Notes
- Fold, Don’t Mix: Use a spatula to fold in the chocolate chips to avoid overmixing the batter.
- Adjust for Smaller Pans: If using an 8×8 or smaller pan, lower the oven temperature to 325°F and extend the bake time slightly.
- Don’t Rush the Cooling: Letting the bars cool fully prevents them from crumbling when you cut them.
- Soft Texture: Note that these cookie bars will be a little softer than a traditional chocolate chip cookie. Yum!

Serving Suggestions
- Wine Pairing: Pair these bars with a glass of sweet Riesling or a robust dessert wine for a cozy treat.
- With Coffee or Tea: Enjoy them as an afternoon snack alongside your favorite hot beverage.
- A La Mode: Serve warm with a scoop of vanilla ice cream for an irresistible dessert.
Storage and Reheating Instructions
- Storage: Keep the bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
- Reheating: Warm individual slices in the microwave for 10–15 seconds to bring back their gooey texture.
