My cake mix cookie bars are my number one go-to easy dessert recipe. This recipe is one of the most loved on my blog. Don’t miss it!

Many years ago, my mother-in-law introduced me to using cake mixes to make cookies. Mind=blown!

Cake Mix Cookie Bars Recipe (1)

After poking around the web for a good cake mix cookie bars recipe recently—because I heart easy recipes—when I came across a great cake mix cookie bars recipe on Southern Bite called The Easiest Chocolate Chip Cookie Bars Ever.

It’s true, this recipe is dead simple, and you’ll end up with soft, golden, ooey-gooey cake mix cookie bars chock full of chocolate chips and M&M’s. Seriously, these are crazy good.

I mean, come on. Look at these photos.

It literally took me like 5 minutes to dump a few simple ingredients into a bowl, pour it into a baking dish, and throw it in the oven.

I am an instant gratification kind of girl, and while I enjoy baking, I don’t have the patience for anything really fancy. I wish I did!

These cake mix cookie bars would make an excellent addition to a holiday party, especially if you’re crunched for time and want something warm, chewy, and delicious with very little fuss.

I have to admit, I could tell these cake mix cookie bars were going to be heavenly just by the way the batter looked and smelled.

The batter was golden, and the bright holiday M&M’s looked like a smattering of twinkling festive ornaments in the bowl.

Of course, after the holiday season, you could use just plain chocolate chips, regular M&M’s or even mini peanut butter cups as mix-ins. Your options are really endless with this recipe.

I’m a fan of soft and chewy, but you could bake these another 10 minutes for crispier cake mix cookie bars.

Before you run off to pin and print this recipe (which you totally SHOULD), I can’t let you leave before I send you over to my special chocolate raspberry bars and my chewy pecan pie bars!

Cake Mix Cookie Bars Recipe (3)

Ingredients

  • 1 Box yellow cake mix (I used Betty Crocker)
  • 1 Small box instant vanilla pudding (just put in the powder!)
  • 1/4 Cup water
  • 3/4 Cup vegetable oil
  • 2 Eggs
  • 1 Cup chocolate chips. I used 1/2 cup holiday mini M&M's and 1/2 cup milk chocolate chips.

Instructions

  1. Preheat your oven to 350 degrees.
  2. Combine cake mix, pudding, water, vegetable oil, eggs, and chips or M&M's in large bowl.
  3. Pour the batter (it's going to be thick) into a greased 9x13 pan. I sprayed my dish with nonstick cooking spray which worked well.
  4. Bake your bars for 20-30 minutes (I took mine out at 25.)
  5. It may look sort of raw in the middle but if the edges are just golden and starting to get crispy, it's probably perfect.

    What do I do if I don’t have a box of pudding ??

    • Crissy Page Reply

      I would get a box of pudding, or find a recipe that doesn’t call for pudding. :)

    These cookie bars are always a hit! I’ve used this recipe for years… but haven’t made them since I noticed Betty Crocker decreased their cake mixes to 13.25 oz. Any modifications to the recipe now that most cake mixes are 13.25 oz instead of 15.25 oz?

    • Crissy Page Reply

      Wow, you know, I never really thought about it! I haven’t tried that yet!

    • Crissy Page Reply

      Haven’t tried it, but probably!

  3. Chris Reply

    When using a boxed cake mix to make cookies or bars, does it taste like a cake or like a cookie? I am curious of the texture.

  4. Chris Reply

    Try chocolate cake mix and peanut butter chips.

  5. Tessa Reply

    Love this bar recipe! Ihave made these many times around the holidays with the original recipe (yellow cake mix, vanilla pudding, chocolate chips, & M&M’s), they are always a huge hit! For a different variation in the Spring / Summer, I made this bar recipe using lemon cake mix, cheesecake pudding, & white chocolate chips)… oh my! Those were divine too! I could also see cheesecake pudding & white chocolate chips working well with strawberry cake mix or even pineapple cake mix to make other variations of these amazing cookie cake bars !

    Can you make these a head of time? How do you store them without drying out?

  7. Abby Reply

    Did you prepare the cake mix or did you just add the powder to the other items?

  8. Anna Reply

    Can I make these into cookies? I need a good, easy recipe for a cookie exchange. If so, any guess on baking time?

      Cookie BARS are considered cookies…I take them to cookie exchanges all the time and they are a HIT!…everyone wants a good recipe that has shortcuts and this takes much less time than individually dropping raw balls of cookie dough…

  9. Nancy Rovatti Reply

    can you make cookies out of this recipe and not bars?
    Thanks Nancy

  10. Maria Reply

    How many servings should come out from this? Also instead of doing bars, would individual cookies bake fine?

  11. Nicole j Scheeler Reply

    did you use the cake mix that used oil or butter?

    • Crissy Page Reply

      Oil!

      • Carrie

        Can you use chocolate cake mix instead of yellow?

  12. Marissa Reply

    Will this work with sugar free cake mix and sugar free pudding?

    • Crissy Page Reply

      Hey Marissa, I haven’t tried it, but I would think so!

  13. Courtney Reply

    Do you think a sugar free cake mix and jello would work for this recipe?

  14. Anne Reply

    Thank you for the great recipe, I made this sugar free by using sugar free cake mix, sugar free vanilla pudding and sugar free chocolate chips..

      Good to know! I just used a GF mix & was hoping it would work. Only had chocolate pudding, ha ha, so I might as well have used a chocolate cake mix.

  32. Michelle Reply

  33. REBECCA STEPHEN Reply

    these cookies look so good, I’m going to make them for my children

  34. Mary Jo Reply

    I have made this before just like recipe and they came out awesome! I got rave reviews from friends and family. This time I changed it and used peanut butter chips and m&ms abs although everyone still liked them, I was disappointed because I couldn’t really taste the peanut butter chips. Still awesome recipe

  35. BeetRice Reply

    Thank you from an overworked mom who doesn’t bake often because it’s such a chore….my poor kids. But now I can do this, and other variations: Chocolate cake with white chocolate chips or nuts, Lemon with poppy seed and orange zest…..

Cake Mix Cookie Bars Recipe (2024)

FAQs

How do you make a box cake taste like it came from the bakery? ›

More Fat, More Flavor

Most box cake recipes call for vegetable or canola oil. The only trouble is, these oils have almost no flavor. Replace the oil with an equal amount of melted butter (and a pinch of salt if using unsalted butter), to boost richness. For an extra decadent cake, add two tablespoons of mayonnaise.

What does adding extra egg yolk do to cake? ›

Because eggs help build the cake's structure (don't use them and you're looking at a gooey mess), adding an extra egg yolk makes the cake batter denser. Translation: you'll have a moister confection. Conversely, she suggests an extra egg white for a fluffier cake.

Can you use milk instead of water in Betty Crocker cake mix? ›

Yes, you can substitute milk for water when preparing SuperMoist cake mixes, however, the cake may be slightly drier than if prepared with water. Also keep in mind that milk will add calories and change the nutrition slightly.

Do professional bakers use box cake mix? ›

As a professional baker, I don't often use boxed mixes, but I appreciate how easily they bring a cake together. I think premade mixes are great for beginners gaining confidence around the kitchen and also for last-minute cake "emergencies."

Should you beat eggs before adding to cake mix? ›

For chemically-leavened cakes — that is, cakes calling for baking powder or baking soda — it's OK if you don't remember to add the eggs until the end. Martina says, “Late in the mixing stage, eggs will incorporate better if you lightly beat them before adding to the batter.

What does adding milk to cake mix do? ›

The milk adds fat, which results in a better flavor and density in your cake. If you want to make your cake extra rich, swap out the milk for buttermilk. Because buttermilk is extra thick, use a few more tablespoons than the recipe calls for.

What happens if you use one less egg in cake mix? ›

If there isn't enough egg, your batter or dough may not be able to hold its structure or could end up overly dry or dense. On the other hand, if there is too much egg, your baked goods could lose their shape due to excess liquid, or have a rubbery (or even overly cakey) texture depending on the recipe.

Are Betty Crocker cakes better with oil or butter? ›

The directions on the back of the box will tell you to add vegetable oil; for a denser crumb and bigger flavor, swap in unsalted butter. Melted butter can be used in the same quantity and manner as the fat called for in any boxed cake recipe.

Is butter better than oil in cake mix? ›

The spongy texture and moist flavor that oil creates can be a boon to certain recipes. Not to mention oil is cheaper and easier to work with. Butter will always provide superior flavor and that melt-in-your-mouth texture. In many recipes, combining the two gives the best of both worlds.

Can I use melted butter instead of oil in box cake mix? ›

Most cake mixes call for oil, but butter will bring in amazing flavor. To substitute butter for oil in baking just melt the butter, measure it, let it cool, and add it as you would the oil. Compared to oil, butter will create a cake with a firmer, cakeier texture.

What does adding sour cream to cake mix do? ›

Sour cream is one of the fattiest dairy products; the extra fat content (for example, adding sour cream to a cake instead of milk) will make the cake moister and richer, says Wilk. "Fat, in any form (butter, lard, cream, etc.) shortens gluten strands, which essentially leads to the most tender baked goods," she adds.

Does box cake taste better with milk or water? ›

Most box cake recipes will tell you to add water to the mix. Instead, try adding milk using the same proportions. This will make the cake richer and creamier because it ups the fat content. You can even use buttermilk here for a pleasant tang.

How much butter to replace oil in cake mix? ›

Replacing Oil with Butter

It couldn't be easier to substitute butter for oil using a 1:1 ratio. This should work with olive, canola, vegetable, and coconut oils. Simply melt and cool the butter to room temperature, then continue with your recipe. (If the recipe calls for ½ cup oil, use ½ cup melted and cooled butter.)
