Cake Mix Cookie Bars

Years ago, my Granny gave me a Cake Mix Recipe Book that included all kinds of different ideas for using a box of cake mix to create a variety of different cookies and various other sweet treats. I had never heard of using cake mixes to make anything other than cakes, so I was intrigued. The first recipe I tried from the book was for Cake Mix Cookies. It was a simple cookie recipe that calls for a box of yellow cake mix. Ever since then, it has been my go-to way of making chocolate chip cookies. Well, until one day when I decided to use the same mixture to bake a batch of chocolate chip bars!

One afternoon, as I went to make cookies for my kids, I found myself wondering what would happen if I whipped up the same simple cookie batter but used it to make Cake Mix Cookie Bars instead of individual cookies. Guess what? It worked like a charm!

Ingredients to Make Cake Mix Cookie Bars

This recipe only calls for a handful of ingredients!

  • 1 Box of Yellow Cake Mix
  • 1/2 Cup of Softened Butter – I usually use salted butter, and as long as it’s reached room temperature, you should be good to go.
  • 2 Eggs
  • 1 Bag of Chocolate Chips – For this recipe, I typically use regular size chocolate chips, but you could always use mini chocolate chips.

How to Make Cake Mix Cookie Bars

  • Preheat oven to 350 degrees.
  • In a large bowl, mix together the above list of simple ingredients. A hand mixer or a stand mixer works just fine. There have even been times when I’ve used a fork to do the job!
  • Spread an even layer of the mixture into a greased or non-stick pan. I typically use a 9″ x 13″ glass pan.
  • Bake for approximately 30 minutes. Depending on your oven and your baking dish, the cook time may vary a bit. Use the toothpick test to make sure the cookie bars have finished baking.

After these easy Cake Mix Cookie Bars come out of the oven, allow them to cool for a few minutes. Then serve them warm with a cold glass of milk.

If there are any leftover bars after your family attacks the pan, you can cover them with plastic wrap or store them in an airtight container and enjoy over the next day or two – if they last that long!
