I have made them for birthday parties, Christmas, dinner gatherings, graduations, and more. Basically any time I am asked to bring a dessert!
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
These are surprisingly so good. I say surprisingly only because it’s so dang simple and seems like there’s no way they could be *that* good. But they are. My picky husband kept going back for more and said they’re “stupid good”
I made them exactly as the recipe shows except baked in an 8×8 dish because I wanted them thicker, baked for a few minutes longer than in the recipe. I can’t wait to try more flavor concoctions with this.
So glad you enjoyed it!!
Delicious and quick!
My tip for the stickiness pressing the dough in the pan… use the bag from the cake mix, flip it inside out and use as a glove! No mess and no waste!
Great tip!
Delicious!!!!!!!!
This was so easy and delicious. I used melted butter instead of oil, used lemon cake mix and used white chocolate chips. Next time I’ll use strawberry cake mix. I also followed the advice of another comment and wet my hands to spread it out, so easy.
Really good! I used less chocolate chips and cooked in a smaller, 7×9 pan for about 23 mins. I also used butter instead of oil, since it’s all I had. It came out wonderfully. Thank you for the recipe!
can you add rhubarb to the mix and if so, how much?
These cookie bars are not only delicious but so easy to make. Who knew a cakemix could transform into delicious brownies?
I found that mine ended up being ‘WAY’ easy to spread, due to them sitting on top of my stove while it was preheating!
Good tip!
To spread the dough just dampen your hands and press. Works for everything especially rice krispie treats. No it doesn’t ruin the bars. Great recipe.
Great tip and so glad you enjoyed the recipe!
I love this recipe!! So easy, my kind of recipe 🙂 I also added Caramel Bits!! Chocolate and Caramel… who can resist that combination!! Great tip, dampening your hands to spread the dough!! That’s a tip I’ll always remember… It seems I’m baking a lot of sticky recipes!!
Love, love, love these cookies. I can’t even tell you how many times I have made them. You know what’s really good in here along with the chocolate chips? Dried cherries. About a cup or so. Yum! Thank you for this recipe.
Yum! Sounds like a great addition 🙂
