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.

These bars are so very good. I made a 13 x9 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.
Wow!! That sounds amazing!!!
Yes! That’s what I want to try! Let me know how that turned out!!
@Bren, I agree, they are wonderful and I feel the flavor combinations are limited only by imagination!
Just made these with my son. I laid parchment paper over the top and just pressed it into the pan. Worked amazing!
i would like to add oatmeal to this recipe how much do I use
The 12 ounces of chocolate chips is a cup and a half. So I used a cup of oatmeal and a half cup of raisins. I used extra-large eggs and an extra tablespoon of oil.
I never saw a reply about the oats. Did someone try a spice mix with oats and how much did you use?
I’m interested in know this too I’m interested in knowing this too
@Pattie, she said that the 12 oz bag of chocolate chips is equal to 1 cup and 1/2. So she used 1 cup of oats and 1/2 cup of raisins. She also used extra large eggs and an extra teaspoon of oil
Just made some cake bars I made yellow and chocolate thanks for the recipe it’s easier than making the normal cookies
Made these as directed but used a Triple Chocolate cake mix. Wowser they were good! Going to try a Spice cake mix next with a cup of Oats and a half cup of raisins.
Yummy! Spiced Oatmeal Raisin is a Hit!
next up will be spice cake mix with dried cranberries and orange zest.
Did you add the oats? Did you need extra liquid? It seems the oats would require something, but baked goods wth oats are delicious. Please LMK how you did this. They sound fabulous. Thank you.
Hello,
Do these freeze well?
Thanks you!!
I haven’t tried it myself, but have found they taste best fresh and start to get a little stale after two days.
I freeze mine so I dont eat them all at once! Yes they freeze well!
Yes, I’ve made these quite often as they are so very good & easy, they freeze very, very nice. I’ve also have added cried cranberries instead of chips & again, so good & freeze very, very well.
Making a batch for my mom’s 80th birthday party. I used oil on my hands to press it out. Works great!
This sounds so good, am making them for my husband tonight. Thank you for this recipe.
I sprayed non stick baking spray on my hands. Then used them to spread out the batter. It worked really well!! Better than trying to use my spatula.
Great idea, thanks for sharing!
Whenever I’m trying to spread thick batter in a pan I just get my hands wet! Anytime the batter starts to stick to my hands I rinse them off & keep on pressing. 🙂
