Easy Cake Mix Cookie Bars

My kids have amazing noses.  They claim that when they come home from school, they can tell before they even open the door if I’ve made them cookies or some other kind of treat…and they’re always right! Today I made them these Easy Cake Mix Cookie Bars, and they were a HUGE hit, as always.  And guess what?  They are THE easiest and fastest recipe for cookie bars you will find!

You guys.  You can mix these up in less than five minutes.  Seriously–I timed it! With just a few ingredients and about twenty minutes, you can have yummy cookies bars right out of the oven.

I like mine thick, so I use a 9×9 baking dish, but if  you want them thinner, then just use a 9×13 baking dish instead.  There are also SO SO many possibilities!  I used a yellow cake mix with chocolate chips this time, but I’ve made a bunch of others, and they’re all so good.  Pretty much anything you can think of works!

-Chocolate cake mix, chocolate chips (add nuts or marshmallows too!)

-Chocolate cake mix, white chocolate chips

-Chocolate cake mix, mint chips

-Chocolate cake mix, peanut butter chips

-Strawberry cake mix, white chocolate chips

-Lemon Cake mix, white chocolate chips

-Yellow Cake Mix, butterscotch chips

-Spice cake, white chocolate chips

  • 1 yellow cake mix, or other flavor
  • 1 egg
  • 3/4 c. butter, melted
  • 1/4 c. sugar
  • Chocolate chips, any type of chips!


  • Mix the first four ingredients together, then stir in the chocolate chips. Spray a 9x9 baking dish (for thicker bars) or a 9x13 baking dish (for thinner bars) with cooking spray, then spread the cookie mix in the dish. Bake at 350 for 15 minutes (9x9) or 10 minutes (9x13), or until lightly browned. We love them served warm with ice cream too!

  1. yummy! this sounds like a great treat to make. i’m thinking a spice cake with raisins would be yummy too. oh i can’t wait to try this recipe. thanks for sharing.

  2. Seriously, you made it too easy to whip up a pan of cookie bars. This is going to be dangerous. I just wanted to let you know that I featured you on my blogs “shout out saturday” feature. Have a great weekend. Patty

    1. It’s true—it’s the easiest cookie bar recipe ever! And SO yummy! :) Thanks so much for the feature! xoxo

    Hi Kierste, I made these today and they’re super-delicious! Thank you! For some reason it took about 40 mins at 350 degrees in a 9 x 9 glass pan for mine to be done. Anyway, I’ll definitely be making these again. :o)

    1. Yay! SO glad you loved them too! And I appreciate you adding how much time yours took to bake–ovens can vary so much! Mine is on the fast side, so it’s good to get another point of view. xoxo

  4. Mine took way longer, too – about 40 mins in the 9×9. I also omitted the extra sugar since regular cake mix is sweet enough for my taste. I just did yellow cake & mini chips but I will definitely try it again with other flavor combos!

    1. It’s so interesting…ovens can really vary. I just learned how much, when we moved into our house. This one is SO much slower than other ones I’ve had. I often have to add quite a bit more baking time. I’m glad you figured it out, though, and that’s a great combo!! xoxo
