Easy Dessert Idea

If you’ve never made cake mix cookies you’ve been missing out on the opportunity to make life in the kitchen so much easier! Chocolate chip cookies bars with cake mix is an easier version of homemade chocolate chip cookie bars because making a boxed cake mix recipe takes over several single ingredients. Fewer steps with equally yummy results!

Cake mix cookie bar recipes have a similar consistency to the cake but with the added butter and eggs and spreading it out thinly to bake, they end up like a giant cookie! They’re soft and moist with added chocolate chips that melt and get all gooey. They taste delicious!

It’s a super simple dessert to throw together anytime, whether your kids want a little sweet treat after dinner with a cold glass of milk, or served warm with a scoop of vanilla ice cream for movie night!

  • Yellow cake mix: You can use any brand of cake mix you prefer. Betty Crocker or Duncan Hines are my go to. Don’t use the ingredients on the box. Follow the recipe as I have it listed below. Otherwise, you will be making a cake!
  • Vegetable oil: This is the fat that adds moisture and richness to the batter.
  • Large eggs: This will bind the ingredients together.
  • Vanilla: A dash of vanilla will do.
  • Chocolate chip cookies: I use semi-sweet as sometimes, but you use whatever you prefer.

How Are Cookie Bars Made With Cake Mix?

Showing how to make cake bars in a 4 step collage.
  1. Combine. Mix together the cake mix, oil, eggs and vanilla just until combined.
  2. Add. Fold in chocolate chips. It will now resemble more of a cookie dough than a cake batter.
  3. Press. Transfer dough to a parchment-lined 9×13 baking dish. Keep in mind the dough will be thick and sticky, so use another piece of parchment paper or a rubber spatula, press down to flatten. Sprinkle a few extra chocolate chips on top.
  4. Bake. Bake in a preheated oven for 20 minutes until golden brown. Allow to cool before slicing and serving.

Variations for Cake Bars

Swap the box of cake mix for a different flavor and use your favorite add-ins!

  • Red velvet and white chocolate chips. Perfect for Valentine’s Day!
  • Devil’s food cake. Double the chocolate with chocolate cake and chocolate chips!
  • M&Ms cookie bars. Use a yellow or vanilla cake mix and toss in some colorful M&M candies.
  • Peanut Butter: Add in a scoop of peanut butter into the batter. Then you can mix in peanut butter chips and peanuts to really amp of the peanut butter flavor. I still like to keep the chocolate chips in there too to balance it all out.
  • Other add-ins to try are crushed candy bars, nuts and butterscotch chips.

Tips for Making Cake Mix Bars

  • You can substitute canola oil for melted butter if preferred.
  • Bring your eggs to room temperature beforehand for even baking.
  • If you don’t have parchment paper on hand, be sure to use any nonstick cooking spray. When it comes time to slice the bars you don’t want them to stick!
  • Do not overmix the mixture. Gently fold in the chocolate chips then leave it alone. This way it won’t become too dense and overworked.
  • Adding a few extra chocolate chips on top before baking is nice for the presentation. No one would blame you if you just ate them instead ;)


How to store cake bars?

Keep any leftover bars in an airtight container in the fridge for up to 3 days. You can also store these cake bars in the freezer for up to 3 months.

Why is it called a bar cookie?

Dessert bars are typically baked in a pan and cut into squares where cookies are baked in the shape of a circle. They are not as fluffy as a cake and have a more similar texture to my cake mix chocolate chip cookies.

Does cake mix actually expire?

Yes cake mix will expire, but you can typically use a few months after the expiration date. If you’re getting close to the expiration date and not ready to bake, you can freeze the mix to get a few more months out of it.
