Cake Mix Cookie Bars Dessert Recipe

These cake mix cookie bars are rich and delicious, but are so easy and take just a few minutes to assemble. They can be served warm and gooey straight from the oven, or let them cool and serve perfect little bars.

This post was first published in 2013. It’s been updated with brand new images and much more information. Enjoy!

Something I would love to do at some point in my life is sort through and organize the recipes in my recipe box.

Yes…I still have a recipe box, and if you’ve followed me for even a little while, you know it’s full of cards, bits of paper, and pages torn out of magazines.

I could never give it up.

In that recipe box, is a card for “Almost Candy Bars.” The recipe card is in my handwriting, but the space for “recipe from the kitchen of” says Mom.

Since my mom passed away several years ago, any reminder of her is always a good thing. I wish the card was in my mom’s handwriting, but just the fact that it was her recipe makes it very special. For this post, I renamed her recipe “cake mix cookie bars,” but all the easy ingredients are the same. It takes just a few minutes to assemble, and pop in the oven.

cake mix cookie bars ingredients
  • I used a 9 x 13 inch baking dish for these cookie bars, but the original recipes says to use a 10 x 15 inch pan. The bigger pan would give you a thinner bottom crust, and the sweetened condensed milk would spread out more. Both versions are delicious!
  • To serve these cake mix cookie bars warm from the oven, just scoop portions out of the pan with a large spoon. Bowls work best, and it’s delicious to add a bit of whipped cream or ice cream.
  • To serve the recipe as bars, make sure to let it cool completely. Use a very sharp knife to make the cuts, and then remove the pieces with a spatula. (Do not use a ceramic knife to cut the bars…it may break!)
  • Store these cake mix cookie bars in an air tight container at room temperature for up to 3 days.
  • Variations: any type of nut can be substituted for the walnuts. Pecans or sliced almonds would be delicious. I recommend using the chocolate chips, but the butterscotch chips can be swapped out with another variety. White chocolate or caramel chips would be beautiful as well as very tasty. I’ve never tried it, but I am fairly sure a yellow cake mix can be substituted for the white cake mix.

These cake mix cookie bars are definitely a splurge, but when you make them, there are plenty to share with family and friends. I took some to my dad, and told him the story of the recipe card. He gave these cake mix cookie bars two thumbs up, and said I could make them anytime!
