I have made them for birthday parties, Christmas, dinner gatherings, graduations, and more. Basically any time I am asked to bring a dessert!

Everyone needs a back pocket simple dessert like this one. I love the simplicity of this dessert, and the taste of a homemade treat that didn’t take me an hour to make.

Ingredients to make cake mix cookie bars

  • yellow cake mix
  • eggs
  • oil
  • chocolate chips
ingredients to make cookie bars with cake mix

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). I have found the easiest way to do this is to use a rubber spatula or greased hands.

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.

Store any leftover bars in an airtight container.

Serve warm with ice cream for an extra delicious treat! Everyone loves them, and I love how simple they are to throw together.

Tips for spreading the batter

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.

If you’ve never made chocolate chip cookie bars with cake mix, you will be surprised at just how good they are!

They are unbelievably easy to make and so freaking good. We love having them warmed up with vanilla ice cream!

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 your leftover cake mix cookie bars

Leftover cake bars can be stored in an airtight container at room temperature for 3-4 days.

Instructions

  1. Preheat oven to 350 degrees
  2. Beat eggs in a small bowl
  3. Add cake mix and olive oil to the beaten eggs and mix well
  4. Beat in chocolate chips (batter will be very thick)

Notes

  1. 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!
  2. The thickness of the cookie bars will depend on how large of a baking dish you use.

I found that mine ended up being 'WAY' easy to spread, due to them sitting on top of my stove while it was preheating!

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.

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.
