How To Make Cake Mix Chocolate Chip Cookie Bars (step-by-step directions)

1. Preheat your oven to the required temperature and properly prepare your baking pan with non-stick spray or parchment paper.
2. Mix the melted butter and eggs in a large bowl until well combined. (Photos 1 & 2)
3. Gradually add the box of cake mix to the wet ingredients, stirring until just combined.
4. Fold in the chocolate chips into the batter, ensuring they are evenly distributed throughout. (Photo 3)

7. Remove from the oven and let the cookie bars cool in the pan before slicing into squares. (Photo 4)

Recipe Tips

• Don’t over mix the batter for these chocolate chip cookies, or can the cake mix cookies a bit dense as it bakes up.
• A 9×13 baking dish is what I used. Use parchment paper to place on the bottom of the pan so you can lift the whole cookie bars out to slice and serve.
• Any brand of cake mix works; just buy whatever you prefer in terms of flavor.
• This truly is an easy recipe for cake mix bars. Measure and bake as directed, and they should turn out fine.
• You can mix in a large bowl with a whisk or use a hand mixer to speed up the prep work. It takes little time to mix up either way.
• When the cookie bars are done, the tops will turn a little golden brown and pull away from the edge of the pan.
• I like to use a rubber spatula to spread the cookie dough evenly in the pan before baking.
• Allow the delicious cookie bars to cool on a wire rack before slicing and serving.

Storing Tips 

For these easy cake mix cookie bars, just store them at room temperature in an airtight container or in plastic wrap once they have fully cooled off from the oven. The cookies will store for up to 4-5 days. I do find the bars are best eaten within a day or two of being made.

If you don’t want to eat these chewy cookie bars all immediately, you can freeze them for later. Just place them in a freezer bag or container and freeze for 3-4 months. Then, when you are ready to eat, thaw them on the counter for 1-2 hours before serving.

Serving Suggestions

For a classic coffee shop vibe, serve them alongside a steaming cup of coffee or espresso, allowing the warmth of the beverage to contrast beautifully with the soft, sweet texture of the bars. Ice cream enthusiasts might enjoy a scoop of vanilla or even pair the cookies with something like fruit roll-up ice cream sandwiches. 

For those looking to add a fruity twist, a dollop of whipped cream accompanied by fresh berries or something like a marshmallow fruit salad is a good option. For the ultimate dessert indulgence, drizzle hot fudge or caramel sauce over the bars right before serving.
