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
If you use a smaller pan for thicker bars, how would you change the bake time?
That will depend on the pan size. You can use a toothpick to make sure the center is done, and the top should be golden brown.
Ready to go in the oven… I used a butter pecan cake mix, added a small packet of vanilla pudding for extra flavor and both butterscotch and white chocolate chips. Can’t wait for them to be done!
Just took them out of oven and look yummy.I used extra light Olive oil and used a pair of poly gloves to spread out dough.Only took a minute to spread evenly.I use them for my hermit bars as well.
My family loves these! Quick and easy. Tip: when spreading spray the back of a spoon or spatula with Pam, makes it so much easier to spread!
I made these 4 times at Christmas lol. I added red and green MM’s so cute and delicious. I’m going to make them today with Valentine MM’s.
great idea!
Can you use white cake mix?
any cake mix works!
I had these ingredients on hand and gave it a try! “Falling off a Log” easy!! I used 1/2 a bag of chocolate chips and mixed the oil w/ some (on hand) apple sauce to try to cut some calories as well. The cake bars came out GREAT and will definitely do them again! Thanks!
Im going to try a chocolate cake mix and put peanut-butter chips in;
sounds yummy!
Made this today and in my daughters words “They are dangerous”!
Haha I would have to agree! So glad you enjoyed the recipe.
I have these in the oven right now! I used a spice cake mix with old fashioned oats and butterscotch chips
Great idea!
