Lazy Chocolate Chip Cookie Bars (+Video)

Lazy Chocolate Chip Cookie Bars are made with boxed cake mix, butter, eggs and chocolate chips. So soft and yummy!

Enter the Lazy Cookie Bar. Made with my favorite pantry item – the boxed cake mix. So versatile, so easy and so yummy. Only 4 ingredients and you probably have them all at home already. It’s not a really thick bar. It’s more like a sheet pan cookie. It’s gooey and I love the edges – those are my favorite.

FREQUENTLY ASKED QUESTIONS:

Can I use other cake mix flavors?

The great thing about this recipe is all the variations you can make. I’ve made these with red velvet cake mix, chocolate cake mix, birthday cake mix and they’ve all been delicious! Also, feel free to use different types of chips or add in nuts. I really love when the holiday baking chips come out. You can really have fun with this recipe and no one will know just how easy it was to make but you!

What size cake mix should I use?

Cake mixes seem to keep reducing in size over the years. They used to be 18.25 ounces and now some of them are down to 14 ounces so baking times will vary depending on the type of cake mix you purchase and how much is in the box. So please understand this before baking. You will need to keep an eye on it. Start with about 15-18 minutes and go from there. 

What toppings can I add?

These cookie bars are fantastic just as they are, but they’re even more delectable with a scoop of ice cream, maybe some chocolate sauce, or whipped topping. Try adding some sprinkles, or even other sauces like caramel sauce or strawberry sauce. Other fun ideas are more baking chips or Magic Shell.

Can I use a different sized baking dish?

I’ve only tested this recipe in a 9×13-inch baking dish. However, we did have a reader who made these in a 9×9-inch baking dish and said they turned out nice and thick.
We also had a reader who doubled the recipe and put it in a high rimmed baking sheet.
Whatever you choose to do, if it’s not the 9×13 dish I used, you’ll need to experiment a bit and start with a lower bake time. Increase baking time as needed and adjust as necessary.

How to store leftover Lazy Cookie Bars?

These cookie bars should be stored in an airtight container and can be kept at room temperature for up to 4-5 days.
You can freeze them for up to 3 months.

INGREDIENTS NEEDED: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE)

  • yellow cake mix– you can make your own Yellow Cake mix too using my homemade yellow cake recipe.
  • eggs
  • butter- I used salted butter, but if you use unsalted, just add a pinch of salt.
  • salted buttersemi-sweet chocolate chips– you could use mini chocolate chips or swap these out for other flavored baking chips.
Yellow cake mix, chocolate chips, eggs, and butter.

Preheat oven to 350F degrees. Spray a 9×13-inch baking dish with nonstick cooking spray. I love to use the kind that has flour in it (Baker’s Joy).

Combine dry cake mix with melted butter and beaten eggs.

This is easier if you have an electric or stand mixer because batter will be very thick. Stir in bag of chocolate chips.

What I like to do is spray my hand with some nonstick cooking spray and then spread the batter around using my hand since the batter is very thick.

 Once it is evenly spread out, put in the oven and bake for about 20-25 minutes.

And like any good chocolate chip cookie, I like to eat these warm so you can usually find me sneaking some bites from this pan before it’s cool! This makes a great base for some ice cream too.

    I made mine w/ Devil’s Food cake mix, mini chocolate chips, crushed candy canes (leftover from Christmas) mixed in. Topped the cookie bars with a simple homemade white icing and sprinkled more mini chocolate chips & candy cane pieces on the icing. Yummy! Thanks for the base recipe to play around with!

    Love the recipe. I tried macadamia nuts and white chocolate chips. There will awesome. Question, would the recipe work with gluten free cake mix?

  3. I just found this recipe and definitely have everything I need to make it. I was wondering if I can do it in a 8×8 or 9×9 pan. The picture shows them as being pretty thin. I’d like them to be thicker. How much longer would I need to bake them?

    1. Hi Gail, I don’t see why not. I haven’t tested the recipe in a smaller pan so I couldn’t tell you for sure about the time. You’ll have to play it by ear and just add on a few minutes at a time. Let me know if you try it!

    Easy dessert recipe I’ve ever made. So delicious (so far only had the batter bowl!) and can’t wait to eat them.

    Easy comfort food, so yummy! I used a sugar free cake mix and sugar free chocolate chips. I added less than half the chocolate chips and some walnuts. I am going to try it with applesauce or greek yogurt instead of the butter.

    Great recipe for vacation, when you want cookies but don’t want to buy all the ingredients. I’ve made them several times, adding dark chocolate chips and toffee bits. Mmmmm!

    Just made amazing!
    USE THIS Dough Spreading HACK!
    Save from using hands To spread Dough in pan.
    Use a Silcon Spatula and it Spreads dough pefectly….so no hands in dough!!
    If it’s a Silicon spatula you Don’t even need to use nonstick spray!

    Came out great! I’m glad you provided a warning about how thick the batter was going to be, you were right. Thank you for the recipe.

    Great recipe! I added crushed Graham crackers on top before baking. When they were done I topped them with marshmallows, put it under the broiler for a minute(watch closely) then drizzled chocolate syrup on top for a smores cookie treat! My whole family loved it! Thank you!

  10. So excited to try this recipe! It look so delicious and simple. Have you ever made the dough a day ahead of time and left in the fridge? I was wondering if that would be okay? Thanks!

    Made this last night – came out great! So easy, too. Personally, I think the bars were a little heavy on the chocolate chip front so next time I will probably do 1/2 cup choco chips and 1/2 cup chopped walnuts…yumm 😛

    Love love love! Used pecans and Hershey Special chocolate chips. So nice to get the same taste and texture as Toll House cookies in half the time and half the work. This is going to be a regular in my household.

    1. Vivian,
      You can use a chocolate cake mix with peanut butter chips or mint chips as an alternative. I have also used chocolate button candies with both chocolate and white cake mixes.

    Looking for recipes using yellow cakemix and your recipe got my attention. These look very much Sunshine Golden Fruit Cookies. They were made with raisins instead of chocolate chips. They ‘disappeared’ from supermarkets some time back in the late ’80’s or early ’90’s.. I plan to make a batch with chocolate chips and try a batch with chopped raisins. Can’t wait! Thanks for sharing! .

    My family LOVES these! I make them with funfetti cake mix and top with Rainbow Chip icing (the best icing ever!). I get requests to make them at every holiday!
