Only Four Ingredients

I love recipes that only call for a few ingredients, and this one tops the list.

This time I made the cake mix cookie bars and took them over to the kid’s tutoring center, and they loved them!

In fact, the recipe calls for four ingredients, to be exact, and what could be easier than that?

The best part is that this recipe was a cinch to make, and I already had the ingredients at the house.

And you can switch out the cake mixes if you’d rather use a white cake, a lemon cake with lemon chips, or even a strawberry cake mix.

  • 1 Box of cake mix
  • Eggs
  • Vegetable oil
  • Chocolate chips

Full printable recipe with measurements and instructions listed at the bottom of the post.

  1. Add the eggs to a large bowl and beat them for a few seconds.
  2. Next, add the cake mix and the vegetable oil to the bowl and mix well. The batter will be thick.
  3. Finally, add the chocolate chips and mix.
  4. Spread the thick batter into a 9″ x 13″ baking dish and bake for about 25 minutes.

Step-By-Step Instructions

Pouring eggs into a glass bowl

Start by adding the eggs to a large bowl. Beat the eggs for about 30 seconds.

Secondly, add the cake mix to the bowl.

For this recipe, I used devil’s food cake mix, but you can use your favorite mix.

Thirdly, pour the vegetable oil into the bowl.

Fourthly, mix all of the ingredients together until they are well blended.

The mixture is going to be very thick, and you’ll need to make sure all of the cake mix lumps are mixed in well.

I used a whisk to beat the eggs and a fork to mix the rest of the ingredients. You can also use a hand mixer or a stand mixer.

Finally, add the chocolate chips to the bowl and combine.

I tend to be a bit of a piggy when it comes to chocolate chips. So, if you want a few add a few. If you want lots of chocolate chips, add them.

You can also add white chocolate chips, milk chocolate chips, peanut butter chips, or just about any type of chips that you like, and that’s what makes this a fun recipe because it’s so interchangeable.

Press the chocolate chip cookie bars to the edges of the pan and bake for 20-25 minutes, or until a cake tester comes out clean.

If you don’t have a cake tester, a thin knife will work just as well.

For this recipe, I used a 9″ x 13″ size pan.

When I first made this recipe, I thought I could get away with a square baking pan and didn’t think that I would need a 9″ x 13″ dish, but they will rise quite a bit while cooking, so don’t go any smaller than this size.

TIP: I used nonstick cooking spray in the pan, but you can also use parchment paper to help lift the bars out when they cool.

Let the bars cool to room temperature for at least half an hour, and then slice them.

The tops of the chocolate chip cookie bars are crunchy, and the insides are chewy and chocolatey and so delicious.

      Thanks so much, Carlee!!

  8. Super simple to make… although I was a little nervous, kind of couldn’t make the batter cover the entire 9 by 13 pan. 🙁

    1. Julie Pollitt says:

      Hi Olivia! It’s almost a toss up between a smaller pan and the 9 x 13. You could probably try a smaller one next time and see how it works out.

  13. Made these and they were wonderful! Can u make a topping like powered sugar and drizzle on top, thank u for sharing your recipes!

    1. Julie Pollitt says:

      I love to hear that! Thank you. Yes, you can make an icing drizzle. Just combine about one cup of powdered sugar and one to two tablespoons of milk and you’ve got the drizzle! If it’s still thick, you can add a little bit more milk. Enjoy!

  19. We had a box of yellow butter cake mix that was near its expiration date and I didn’t want to make a cake so I searched for recipes and decided to give this a try with it instead of chocolate. I agree with 1 other comment. The hardest thing about this recipe is getting it in the pan but I used a spatula and kind of mushed it down with the end. I was worried I did something wrong. It’s almost the consistency of Play-Doh. I think you could use a smaller pan but then you’d need to watch baking time. This came out perfectly and while I’m more of a chocolate lover and might like the Devil’s food better, I do love a blondie and the 2 vanilla lovers in my house really liked this. I’ll definitely make this again, next time with Devil’s Food but I’m glad it works for other flavors. It’s super easy and a big hit.

      This is great to hear! Thanks so much for sharing!

  20. I have made this recipe several times and it’s amazing.
    The texture is like play dough before cooking and hard to put in pan so
    I place parchment paper the size of my 9 by 13 pan onto counter then
    place another sheet on top, and roll it out to fit.
    Flip it into my pan then with paper still on top press into corners.
    I remove the top paper before baking and it turns out perfect every time.
    I am surprised every time how much they rise.
    Thank you so much for recipe.

    1. Julie Pollitt says:

      What a great way to add it to the pan. Thanks for the tips!!

  21. Jen Crowe says:

    I used wax paper to spread in pan and I am going to top with a thin layer of choc frosting

    1. Julie Pollitt says:

      That sounds wonderful!

  22. Wrote my comment in the wrong space so here it is again
    Would a tbsp of orange juice make the dough easier to spread and chocolate is good with orange

    1. Julie Pollitt says:

      Hi Audrey,
      I am not sure about the orange juice. I haven’t tried that before. And yes, chocolate is always good with orange!

  23. Had a last-minute request to bring something to share for a women’s brunch at church. I only had 2 eggs and a dark chocolate cake mix…so Pintarest to the rescue.😊 These were delicious and simple, kind of like a fudge brownie. Everyone raved about them and wanted the recipe. I’ll definitely be making these again!

    1. Julie Pollitt says:

      That’s awesome to hear! Thanks for sharing! People always bring the yummiest foods to church brunch!
