Can you make cookie bars out of cake mix?

Yes, and it is so easy! Cake mixes are great to work with because they give a pop of flavor and already have several of the leavening agents and salt mixed into the flour, so you cut down on ingredients.

Cake mix cookies are a great option, but that means you can also press the cake/cookie batter into a 9×13 pan and end up with chewy cookie bars. Imagine the possibilities with all the varying flavors of cake mix!

How to Make Lemon Cake Mix Cookie Bars

  • Preheat the oven to 350° F and spray a 9×13 casserole dish with cooking spray.
  • In a medium bowl combine cake mix (dry mix only), eggs, and melted butter until well combined. The batter will be stiff.
  • Press cookie bar batter into the bottom of the casserole dish evenly so that bars are uniform in size and thickness.
  • Bake for about 20 minutes or until the top is light golden brown and the bars are set.

You can serve the bars at room temperature, but they will be very soft. To make them easier to cut, allow them to refrigerate for 3-6 hours.
