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.

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!

These are amazing! The first time I made them I didn't have enough of regular chocolate chips so I used a combo of dark, semi-sweet and milk chocolate. They were so good I do that every time now. I warn people that the batter is more like bread dough than batter. That seems to help their mindset. Using a spatula coated with cooking spray helps. This is a fantastic recipe, thank you for sharing!

Turned out great. Everyone loved them. Don't understand why everyone has to comment on their spin on your idea. Make it the way you want but don't try to take away from what Joy has shared with us all. Wouldn't change a thing!

I made this yesterday and I put a bit of a twist to them myself. I had a box of milk chocolate cake mix and paired that with Reese's peanut butter chips. And had a white confetti cake mix and added mint chocolate chunks to that one. Both turned out great. This was super easy to make, so this will definitely be a go to baking recipe. Are a great addition to our lunchbox meals. I found that I sprayed my hands with some Pam and worked the batter into the pan was the easiest. Thank you for this recipe

Just a helpful tip...when you are ready to spread the batter in your pan, wet your hands with cold water and push it down spreading it out as you go. You may have to repeat this more than once, but it works amazingly and is much faster than fighting with your spatula.

I just made these and they are still warm out of the oven. I only had a chocolate cake mix, so used that. I didn't have trouble spreading them into the pan as I added a little more of oil. I then put my hand inside of a qt. size storage bag to do the spreading. No trouble whatsoever. I added chopped walnuts to my half. My husband will love these because #1, he likes fluffy soft cookies and #2, they taste like a brownie. Next time I would use a larger pan so they aren't as thick. I used a 9X13 as stated in teh recipe..I like a crispier "cookie". Over all I have to say these are very good, and so easy to make.
