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.

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.

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

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.
