What You’ll Need for Chocolate Cake Mix Cookie Bars
This recipe calls for simple, pantry-friendly ingredients that come together to create a melt-in-your-mouth dessert.
Ingredients for the Cookie Bars:
- 1 box of chocolate cake mix (any brand or flavor will work; you can even use red velvet or white cake mix for a different twist)
- 5 tablespoons melted butter (for richness and a buttery texture)
- 2 large eggs (to bind the ingredients together and create a soft, chewy texture)
- 12 ounces chocolate chips (use semi-sweet, milk, or dark chocolate chips, depending on your preference)
Optional Add-ins (for extra flavor and texture):

How to Make Chocolate Cake Mix Cookie Bars
Making these chocolate cake mix cookie bars is as easy as it sounds. Here’s the step-by-step guide to perfecting your bars every time:
Step 1: Preheat the Oven
Preheat your oven to 350°F (177°C) and grease a 9×13-inch baking pan with cooking spray or line it with parchment paper for easy cleanup.
Step 2: Make the Cookie Dough
- In a large mixing bowl, combine the chocolate cake mix, melted butter, and eggs. Stir until the dough comes together. The dough will be thick, but don’t worry—that’s exactly what you want.
- If you’re adding any mix-ins (like chocolate chips, nuts, or candy), fold them in now.
Step 3: Spread the Dough
Spread the cookie dough evenly into the prepared baking pan. Use a spatula to smooth out the top so it’s even across the surface.
Step 4: Bake the Bars
Place the pan in the preheated oven and bake for 25-30 minutes. Check the bars at the 25-minute mark by inserting a toothpick into the center. If it comes out clean, they’re ready. Be careful not to overbake them; you want them to stay soft and chewy.
Step 5: Cool and Slice
Let the bars cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely. Once they’re fully cooled, cut them into squares or rectangles and serve!
Tips and Tricks for the Perfect Cookie Bars
To make sure your chocolate cake mix cookie bars turn out perfectly every time, here are a few tips:
1. Don’t Overmix the Dough
While mixing, try not to overwork the dough. Overmixing can lead to a denser texture, and you want your cookie bars to be soft and chewy.
2. Customizing Your Flavor
Feel free to customize the flavor of these bars:
- Switch up the cake mix: If you’re feeling adventurous, try using red velvet cake mix for a unique twist or vanilla cake mix for a lighter base.
- Experiment with add-ins: Add peanut butter chips or toffee bits for a fun new flavor.
3. Baking Time
Ovens can vary, so keep an eye on your bars while they bake. Start checking at 25 minutes. If the edges are golden and the center is set, they’re done. Slightly underbaking them can give you a chewier texture.
4. Frosting Options
For an extra indulgent treat, top your bars with a chocolate ganache or cream cheese frosting. This is especially delicious if you’re making these bars for a special occasion or celebration.
5. Let Them Cool
It’s tempting to dive into the warm cookie bars right out of the oven, but allowing them to cool for at least 10 minutes makes cutting and serving easier. Plus, it helps them firm up so you get perfect bars every time.

Storing and Freezing Your Cake Mix Chocolate Chip Cookie Bars
