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
I used a blend of dried cranberries, dried cherries, and golden raisins and they came out incredibile.
I made these in an 11×7 pan and baked them for 30 minutes. They turned out great, thick and chewy.
I normally don’t comment on recipes. Where was this when my kids were little and I needed items for bake sales regularly?!?
I used vegetable oil, tripled the recipe and divided between 2 jelly roll pans. I got 40 perfectly done 2” squares per pan.
Absolutely the easiest baked item ever. Delicious!
thanks for taking time to leave a comment! So glad you enjoyed the recipe 🙂 Definitely a perfect treat for bake sales.
These are so good! Would it be better to flour the pan or does just greasing it work better? I floured it the first time but it seemed somewhat unnecessary because the dough is very sticky and was pulling up the flour as I spread it out
@Caitlin, I just greased the pan, then greased my hands and the batter patted right out to the edges of the dish.
@Tamara,
Found an easier way. Just use parchment paper to spread it in the pan. So easy, not messy and doesn’t stick
@Sherry, :I just tried this method and you are right. Easy.
I used a yellow cake mix with dark chocolate chips. When done I drizzled melted chocolate on top. Yum yum!
@Linda W,
I did the same except drizzled peanut butter over the pan before cutting into pieces
These were delicious, can’t wait to try chocolate cake mix and peanut butter chips.
@Patrice, I made them tonight with a chocolate cake mix and pb chips. AMAZING!
To flatten out the dough in the pan I used the plastic bag that the cake mix was in. It worked great and it was handy and right there to use.
@Pat, that’s using what’s already there instead of another tool. I tried it and never again will throw it away with the box. Thanks for your practicality!
So good! I added a little bit of cocoa powder to make sure there was no ‘cake mix’ taste. Also spread a little peanut butter on a corner when they were hot to see how that would go…..These are delicious!
I would like to know what changes should be made to use a half-sheet pan
@vickie,
I tripled the recipe and divided between 2 jelly roll pans. Cook time was 20-25 minutes. I yielded 40 2” bars per pan.
I also used parchment paper and then the vegetable spray to prevent sticking.
I found a piece of parchment paper makes pressing and spreading the batter out is much easier and faster.
@PATRICIA ANN WAYMAN,
Great idea! thank you
