    • Nuts: Add crunch and depth with chopped walnuts, pecans, almonds, or macadamia nuts.
    • Candy Pieces: Crush up your favorite candies like M&M’s, Reese’s Pieces, Heath bars, or Oreos for extra texture and flavor.
    • Dried Fruit: For a chewier texture and a hint of tang, include dried cranberries, cherries, or raisins.
    • Sprinkles: A handful of sprinkles mixed into the batter or sprinkled on top before baking can make them extra festive for any occasion.
    • Coconut Flakes: Add a tropical touch and chewiness.

Feel free to mix and match! A chocolate cake mix with peanut butter chips and chopped peanuts, or a yellow cake mix with white chocolate chips and dried cranberries, could become your new favorite combination. This recipe truly empowers you to be an innovator in your kitchen!

While you can find the full, detailed recipe and instructions in the dedicated recipe card at the bottom of this post, let’s walk through the simple steps and essential ingredients you’ll need to create these delightful treats.

Essential Ingredients You’ll Need

The beauty of this recipe lies in its incredibly short and simple ingredient list. You only need four items to get started!

  • Yellow Cake Mix: This forms the base of your cookie bars. A standard 15-ounce box works perfectly. As mentioned, feel free to swap in any flavor of cake mix you prefer to customize your bars!
  • Eggs: These act as a binding agent, holding everything together and contributing to the chewy texture.
  • Oil: A neutral oil like olive oil or vegetable oil works best. It adds moisture and helps create that wonderful soft, chewy consistency without imparting strong flavors.
  • Chocolate Chips: The classic mix-in! Semi-sweet is a popular choice, but milk, dark, or white chocolate chips are also fantastic.

That’s it! Just four simple ingredients standing between you and a pan of delicious, homemade cookie bars.

How to Make Cake Mix Cookie Bars: Step-by-Step Guide

Making these cookie bars is incredibly straightforward. Even beginner bakers will find this recipe foolproof. Just follow these simple steps:

Step 1: Prepare the Batter Base. First, preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius) to ensure it’s ready for baking. In a medium-sized mixing bowl, beat the eggs until they are well scrambled. This helps to integrate them smoothly into the batter. Next, add the entire box of cake mix and your chosen neutral oil (like olive oil or vegetable oil) to the beaten eggs. Mix these ingredients thoroughly until they are well combined. The mixture will start to come together into a thick, cohesive dough.

Step 2: Incorporate the Chocolate Chips (or your chosen mix-ins!). Now it’s time for the stars of the show! Add your chocolate chips to the prepared batter. Using a sturdy spoon or even your hands (lightly floured or greased, if preferred) work them into the thick batter until they are evenly distributed. Don’t be alarmed by how thick the batter is – this is perfectly normal and contributes to the dense, chewy texture of the finished bars. This is also where you could add any other mix-ins you desire, such as nuts, sprinkles, or other candy pieces.

Step 3: Spread the Batter in the Baking Dish. Lightly grease a 9×13-inch baking dish with cooking spray or butter. This will prevent the bars from sticking and ensure easy removal. Because the batter is exceptionally thick and sticky, spreading it evenly in the dish can take a few minutes. Don’t rush this step! Take your time to press and spread the batter into an even layer from edge to edge. A good tip for this step is provided below!

Recipe Tip: Taming the Thick Batter!

The cookie bar batter made from cake mix is wonderfully thick, which is what gives these bars their fantastic texture. However, it can be a bit challenging to spread! To make this task much easier, try lightly **wetting your hands with water** or **greasing them with a little oil or cooking spray**. Alternatively, a sturdy rubber spatula or the back of a greased spoon can also work wonders to evenly press the batter into the baking dish without it sticking to everything.

Step 4: Bake, Cool, and Cut. Place your baking dish into the preheated oven and bake the cookie bars for 20 to 25 minutes. Baking times can vary slightly depending on your oven, so keep an eye on them. You’ll know they’re done when the edges are lightly golden, and a toothpick inserted into the center comes out clean or with moist crumbs, but not wet batter. Avoid overbaking to keep them soft and chewy. Once baked, remove the pan from the oven and allow the cookie bars to cool completely on a wire rack before cutting them into squares. Cooling completely ensures clean cuts and allows the bars to set properly, enhancing their chewy texture.

Serving Suggestions & The Unforgettable Texture

While these cake mix cookie bars are absolutely delicious on their own, especially when still slightly warm, you can elevate them even further with a few serving suggestions. A scoop of vanilla bean ice cream melting over a warm cookie bar creates an extra special treat, turning a simple dessert into a decadent experience. You could also drizzle them with chocolate syrup, caramel sauce, or a dusting of powdered sugar for added flair.

If you’ve never tried making these before, prepare to be wonderfully surprised by their incredible taste and texture! The unique characteristic of these bars is their delightful consistency: they boast the **thickness and richness of a brownie** combined with the comforting, chewy **taste of a classic chocolate chip cookie**. Each bite offers a satisfyingly dense and moist chew, bursting with chocolatey goodness. They are truly enjoyable to eat – a perfectly thick, rich, and incredibly chocolatey indulgence that satisfies every time.

Storage Tips for Optimal Freshness

If you somehow manage to have any leftovers (which is a rare occurrence in my house!), proper storage will keep your cake mix cookie bars fresh and delicious for several days. These bars are quite resilient and maintain their wonderful texture well.

Storing Your Cookie Bar Leftovers

To keep your cookie bars at their best, store them in an airtight container at room temperature. They will remain fresh and delightfully chewy for about 3-4 days. For longer storage, you can also freeze individual bars wrapped tightly in plastic wrap and then placed in a freezer-safe bag for up to 2-3 months. Thaw at room temperature or warm gently in the microwave for a quick treat!

Instructions 

  • Preheat your oven to 350 degrees Fahrenheit (175°C).

Notes

  1. The batter will be quite thick and somewhat challenging to spread. This is completely normal and ensures the chewy texture of the bars. Using a rubber spatula, a greased spoon, or lightly wet/greased hands will make spreading much easier. Take your time to get an even layer.
  2. The final thickness of your cookie bars will vary slightly depending on the exact size and depth of the baking dish you use. A 9×13-inch pan yields a perfect medium-thick bar.
  3. For extra richness and flavor, you can gently press a few extra chocolate chips or sprinkles onto the top of the batter before baking.
