You can find the full recipe and instructions at the bottom of this post, but here’s what you’ll need to make it.
Ingredients You’ll Need
- yellow cake mix: or any flavor cake mix
- eggs
- oil: any neutral oil like olive oil or vegetable oil
- chocolate chips
How to make cake mix cookie bars
Step 1: Preheat your oven to 350 degrees. Beat the eggs in a small bowl. Add the cake mix and oil to the beaten eggs and mix well to combine.
Step 2: Beat in the chocolate chips (the batter will be very thick).
Step 3: Grease a 9 X 13 baking dish with cooking spray. Spread the cookie bar batter evenly in the dish (this will take several minutes to spread evenly).
Recipe Tip
Use wet or greased hands or a rubber spatula to spread the batter into the dish. The batter is very thick and this will make it a little easier to spread!
Step 4: 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.
Serve warm with ice cream for an extra delicious treat!
If you’ve never made these before, you will be surprised at just how good they are!
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
Leftover cake mix bars can be stored in an airtight container at room temperature for 3-4 days, if they last that long!

Notes
- The batter will be thick and hard to spread (this is normal). I found that using a rubber spatula and a spoon made it easier to spread into the pan. It may take a couple minutes, but it’s so worth it!
- The thickness of the cookie bars will depend on how large of a baking dish you use.
Nutrition
Just as a note for anyone looking to simplify the spreading of the dodo: clean wet hands will spread the dough in a matter of seconds once it’s in the pan. Just make sure your hands and fingers are wet with cold water, and press out the dough. Simple!
@Alan’s Wife, oh great idea that was the hardest part.
Thanks
@Alan’s Wife, Great tip! I tried this, and it made it so easy!
I made this with a boxed butter cake mix and milk chocolate chips. It tasted awesome. But my chocolate chips all settle to the bottom during baking. What did I do wrong??
@Mona Walton, Dust the chips with flour first–unsinkable.
@Mona Walton, mix the chips in your cake mix first to coat, then add oil and egg. this is true of anything you add in – nuts, fruit, whatever. you can use plain flour, but the cake mix works the same and doesn’t change your flavor
I’m so gonna try this but make it with sprinkles and yellow cake
This looks delicious, thank you for sharing!
Made this with white box cake mix, because that’s all I had during this crazy 2020, and butter. It turned out super good!
Was just wondering because all I have is white mix!
@Shannon, thanks! White cake is what I have too! I’m gonna try it to
LOVE to cook, HATE to bake, but LOVE baked goods…. this is PERFECT!!!!
Think I’ll even sprinkle chocolate chips on top when it comes out of the oven and frost It.
Cant wait!
I just made these for the first time. You were spot on about the rubber spatula! I sprayed it with nonstick spray, and it was so easy to press the mix into the pan. I can’t wait to taste them!
@Julie, I dropped big dollops of the dough in various places in the pan and used a rubber spatula to press out and connect them. It took a minute or two tops!
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!!! For getting sticky batter into the pan I put a little olive oil on my (clean) hands and smooshed it right down.
How much oil do we use? Do we use what is required on the cake box?
the recipe and ingredient amounts are located in the recipe card at the bottom of the post 🙂
I am super confused. It says oil(olive oil or apple sauce) BUT it shows EVOO and nothing in a recipe for apple sauce. But does show butter. HALP!
any of the above will work 🙂
They may all work, but how much applesauce is the question It gives how much oil or butter, but not applesauce
You can use any of them in the same amount listed in the recipe.
