Today I am sharing with you one of the most delicious and simple desserts that you’ll ever make!
These cake mix cookie bars have fast become top of my easy dessert list.
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

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 the chocolate chips (the 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 the cookie bars 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!
Everyone loves them, and I love how simple they are to throw together.
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.

If you’ve never made chocolate chip cookie bars with cake mix, you will be surprised at just how good they are!
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 as long as you use dairy free chocolate chips.
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.
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.

So easy and super good! My kids love cookie cake and I made this as an alternative for my daughter’s bday. I used strawberry cake mix and white chocolate chips! It was so delicious and my 5 kiddos loved it! Will definitely be making this more.

I love this simple recipe and make it often. I use the bag that the cake mix comes in to spread/flatten the dough in the pan. After putting dough in the pan I simply lay the bag on top and use my hands to spread the dough The bag is like waxed paper and doesn't stick. So much easier!
