These cake mix cookie bars are made with just 4 ingredients and everyone loves this easy dessert recipe! The only thing better than yellow cake mix cookies is cookie bars!

Today I am sharing with you one of the most addictive (and simple) desserts that you’ll ever make!
It has fast become top of my easy dessert list.
These 4 ingredient cake mix cookie bars are one of my go to desserts to make for parties or family gatherings.
Have a bake sale coming up and need an easy dessert recipe? This recipe and these cake mix banana muffins are two of my favorite ways to use a box of yellow cake mix!

I have made them for birthday parties, christmas, dinner gatherings, graduations, and more.
Basically any time I am asked to bring a dessert!
Everyone needs a back pocket simple dessert like this one.
I love the simplicity of this dessert, and the taste of a homemade treat that didn’t take me an hour to make.
Ingredients to make cake mix cookie bars
- yellow cake mix
- eggs
- oil (or applesauce)
- chocolate chips or chunks
Full ingredients and amounts are at the bottom of the post in a handy printable recipe card!

How to make cake mix cookie bars
Preheat your oven to 350 degrees.
Beat eggs in a small bowl.
Add cake mix and olive oil to the beaten eggs and mix well.

Beat in chocolate chips (batter will be very thick).
Grease a 9 X 13 baking dish with cooking spray.
Spread batter evenly in the dish (this will take several minutes to spread evenly).

Bake at 350 degrees for 20 – 25 minutes, or until toothpick inserted comes out clean. Once cooled, cut the cookie bars into squares. Store any leftover bars in an airtight container.

Serve warm with ice cream for an extra delicious treat! I have made these cake mix bars countless times for family gatherings, birthday parties, and the holidays. Everyone loves them, and I love how simple they are to throw together.
“Thank you for a ridiculously EASY recipe! Great use for all those partial bags of chocolate chips in the bottom of the freezer. It’s in the oven right now and smells amazing!!!“

Tips for spreading the batter
Keep in mind when you make the batter, it will be very thick. My preferred way to distribute the batter evenly is by using a rubber spatula.
It will take you a few minutes to press it down into the pan, but the rubber spatula is a lot easier to use for this than other kitchen tools I have tried. If you don’t have a rubber spatula, you can try greasing your hands to help press the batter down.
Why I love these cookie bars
If you’ve never made chocolate chip cookie bars with cake mix, you will be surprised at just how good they are!
These cake mix bars are seriously so good.
Have I said that yet?!
One bite and you will wonder how you ever lived without trying one!
That sounds dramatic, but it’s how I felt the first time I tried this recipe!
They are unbelievably easy to make and so freaking good.
We love having them warmed up with vanilla ice cream!

It’s also dairy free for anyone with allergies!
The texture of these bars is the thickness of a brownie with the taste of a chocolate chip cookie.
They’re just so fun to eat and really satisfying and thick and chocolatey.
“These bars are so very good. I made a 13×9 pan and they were gone in a day. It’s dangerous to keep these around. Thanks so much for recipe. I am going to try it with a chocolate cake and peanut butter chips next time.“

Storing your leftover cake mix cookie bars
The bars stay soft and chewy even after they cool.
Just make sure to cover or store in an airtight container!
For example, I store mine either in a ziploc bag or a closable container with a lid.

The thickness of the bars will depend on how large of a baking dish you use.
I prefer them to be thick and chewy, but you might like them thinner.
If so, just use a bigger baking dish and adjust cook time as necessary!

I mean seriously…how can you resist that gooey chocolate chip cookie bar staring you in the face ?!

I’ve made this recipe before and it’s good. I used yellow cake mix with dark chocolate chips and toffee chips.

They were amazing!! I had an unexpected phone call, from a close friend, that she was inviting herself for a dinner, here at my place the next day!! It's a long story, but I think that you get the drift of it! Panic buttons start going off everywhere! Needless to say, I had to do the baking first! I found this recipe in faves, and BINGO, that was the one! I thought that I might, try tweeking it a bit! So I substituted half of the chocolate chips with raspberry chips! I used a Pyrex glass, (13x9") dish, and baked it for 23 minutes. I then drizzled melted chocolate over the top for a "fancy", look. I served it with the half white, the half chocolate ice cream, topped with some fresh raspberries! They were a huge hit!!! So I thank you for this recipe, and putting smiles on everyones faces!!!! "The recipe that cannot stop giving!"

Absolutely delicious and a quick and easy last minute dessert!!! 9x13 pan creates the perfect thickness and using a greased spatula makes it way easier to flatten the dough. Thanks for a great recipe!!!
