Twix Chocolate Chip Cookies Recipe

I have a thing for Twix Bars. And for chocolate chip cookies. And my favorite chocolate chip cookie recipe is even better with Twix baked in.

I loved these Twix cookies and I knew I would, because I’ve made them before. Not quite these exact cookies, but I’ve made Soft and Chewy M&M’s Cookies and Snickers Chocolate Chip Cookies, which are both adaptations of my favorite chocolate chip cookies, Chocolate Chip and Chunk Cookies.

I love the dough base because it produces consistently soft and chewy cookies, isn’t fussy, it’s sturdy enough to load up with add-ins, and readers write with success stories when they try it. So if it ain’t broke, don’t fix it.

Just add Twix.

I’ve posted many times about what makes this dough unique and why cookies made with it turn out soft and chewy every time. It’s cornstarch.

It keeps the cookies so soft and light, like Keebler Softbatch cookies, without being dry or cakey.

For anyone who’s tried Pudding Cookies or Cake Mix Cookies, those cookies turn out so soft because the first ingredient in pudding or cake mix is usually ‘modified food starch’. Adding a couple teaspoons of cornstarch to this dough lends similar results.

They’re so soft and light. The centers are moist and tender, while the edges are a bit firmer with some chewiness.

The chunks of milk chocolaty Twix in every bite are the perfect crunchy contrast to the smooth, buttery dough. And there’s plenty of semi-sweet melted chocolate chips, adding another dimension of chocolate.

You can never have too much chocolate. Or candy bars. I love caramels and chocolate.

And the caramel inside the Twix that drips and oozes makes for messy but wonderfully rich bites.

I could happily go down the candy aisle grabbing bags of Reese’s Pieces, Peanut Butter Cups, 100 Grand Bars, Milky Way Dark, Butterfinger, and start baking them into this dough.

I just may.

What’s in Twix Cookies? 

This is the perfect recipe to make using leftover Halloween candy! Here’s what you’ll need for the Twix cookie recipe: 

  • Unsalted butter
  • Light brown sugar
  • Granulated sugar
  • Egg
  • Vanilla extract
  • All-purpose flour
  • Cornstarch
  • Baking soda
  • Salt
  • Twix 
  • Semi-sweet chocolate chips

How to Make Twix Cookies

They’re very straightforward and easy to make. Cream the butter, egg, sugars, and vanilla very well, about 5 minutes.

Add the dry ingredients and mix until just combined before folding in diced Twix and chocolate chips. If you have another candy bar you prefer, go for it.

The dough must be chilled for 2 hours (at least!) prior to being baked. 

Twix Cookies — My favorite chocolate chip cookies, but stuffed with Twix! Soft, chewy, and look at all that gooey caramel!

Bake the Twix bar cookies for 8 or 9 minutes, not more than 10. They may look grossly underdone and very glossy at 8 to 9 minutes, but they firm up dramatically as they cool.

Don’t wait to pull them from the oven until you think they’re done. That’s way too late, and they won’t be tender, soft, and moist.

I sometimes make the mistake of thinking they’re not done at 8 minutes and leave them in closer to 10, but always prefer 8 minute cookies. I like my cookies soft and gooey, but suit yourself.

How to Store the Cookies

The dough can be stored in the fridge for up to 5 days before baking. I usually bake a half dozen or so at a time, just what I know we’ll eat that day.

The cookies stay soft for a week, longer than any other recipe I’ve tried, but warm and freshly baked is always best.

Can I Use Another Type of Candy?

Go for it! Use any leftover candy bars you have lying around. Just note that different candy bars have different fillings, which might ooze out more / less than Twix bars in the oven. Use your best judgement!

Tips for Making Twix Cookies

I try to strategically place the Twix pieces on the top and sides of the cookies rather than the bottoms, so I can see the big Twix hunks as I bite into them, and so they’re not sizzling directly on the baking sheet.

If you notice an exposed hunk towards the base, relocate it to the top or side. It’s not imperative, but just a little trick.

The dough must be chilled for at least 2 hours before baking or the cookies will bake thin and will be prone to spreading. If you want thick, soft, puffy cookies, with chewy plump edges, chill your dough. If you don’t chill it, all bets are off.

Twix Bar Chocolate Chip Cookies

My favorite chocolate chip cookies, but stuffed with Twix! Soft, chewy, and look at all that gooey caramel!

Prep Time 10 minutes
Cook Time 8 minutes
Chill Time 2 hours
Total Time 2 hours 18 minutes


  • 3/4 cup (1 1/2 sticks) unsalted butter, softened
  • 3/4 cup light brown sugar, packed
  • 1/4 cup granulated sugar
  • 1 large egg
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 2 teaspoons cornstarch
  • 1 teaspoon baking soda
  • pinch salt, optional and to taste
  • 1 1/2 cups Twix, diced small and loosely piled in measuring cup (I used 26 mini size (not Fun Size) Twix from an 11.5-ounce bag; each bar diced into 4 small pieces)
  • 3/4 cup semi-sweet chocolate chips


  1. To the bowl of a stand mixer fitted with the paddle attachment, combine the butter, sugars, egg, vanilla, and beat on medium-high speed until well-creamed, light and fluffy, about 5 minutes (or use a hand mixer and beat for at least 7 minutes).
  2. Stop, scrape down the sides of the bowl, and add the flour, cornstarch, baking soda, optional salt, and mix until just combined, about 1 minute.
  3. Add the Twix, chocolate chips, and beat momentarily to incorporate, or fold in by hand.
  4. Using a medium 2-inch cookie scoop, form heaping mounds (I made 28). Place mounds on a large plate, flatten mounds slightly with your palm, cover with plastic wrap, and refrigerate for at least 2 hours, or up to 5 days, before baking. Do not bake with warm dough because cookies will spread and bake thinner and flatter.
  5. Preheat oven to 350F, line a baking sheet with a Silpat Non-Stick Baking Mat, parchment, or spray with cooking spray. and place mounds on baking sheet, spaced at least 2 inches apart (I bake 8 cookies per sheet).
  6. Bake for 8 to 9 minutes, or until edges have set and tops are just beginning to set, even if slightly undercooked, pale and glossy in the center. Do not bake longer than 10 minutes as cookies will firm up as they cool (The cookies shown in the photos were baked with dough that had been chilled overnight, allowed to come to room temp for 15 minutes, and were baked for 8 minutes, with trays rotated at the 4-minute mark. They have chewy edges with soft, pillowy centers).
  7. Allow cookies to cool on the baking sheet for 5 minutes before removing and transferring to a rack to finish cooling.


Storage: Store cookies airtight container at room temperature for up to 1 week, or in the freezer for up to 3 months. Alternatively, unbaked cookie dough can be stored airtight in the refrigerator for up to 5 days, so consider baking only as many cookies as desired and save the remaining dough to be baked in the future when desired.

  1. I just wanted to clarify something. So, do I have to form the cookies first, before chilling the dough, or can I just chill the dough in the bowl, and form the cookies right before baking? That would certainly fit in my refrigerator more easily!

    1. Do the former. If you do the later, you are going to end up trying to chisel rock hard dough out of a bowl which is frustrating, slow, messy, and not easy. I know this fits better but place the balls close to each other on a large dinner plate and then place the plate where you can wiggle it in to your fridge.

  2. Hi Averie,I make this receipe ‘all the time’ on a bake date with my niece. Just out of curiosity, I froze the dough but when I cooked them they spread out big & flat. Is it maybe that I did it roll the cookie dough balls firm enough? Even though they were flat gooey they were still amazing! I am just wondering what I did wrong? 🤔 Anyway I am about to put the rest of these in the oven with your best M&M cookies…you are my go to for cookies 😄

    1. Thanks for the 5 star review! I would say you undermeasured the flour possibly (in more humid times of the year sometimes you need a bit more flour than during winter months or when it’s drier).

      And/or baking soda not fresh, the balls not tight enough as you said, not using a Silpat…hard to say but glad they were still amazing!

  3. Hi Averie! Would it be possible to make these and freeze the dough so that I can bake them up at Christmas time? Trying to get a head start on cookie baking season. Thanks!

  4. If I just use chocolate chips and no other treat, do I add more chocolate chips than you say in the recipe?

  5. I just made these and they are delicious. I’ll try overnight chilling next time to compare as you said this was better, and also the King Arthur flour. I did have trouble with caramel oozing out onto the cookie sheet and thus loosing more than I would like. Any suggestions to help this? Thank you for the recipe!!

    1. Make sure there’s no Twix bar pieces near the edge of the cookies and you may have to literally hand place them just on top of the cookies and make sure the side pieces are shielded with cookie dough, THEN chill the balls (that reduces spreading which will reduce the oozing) and then bake. And KA Flour is really a nice little insurance tip, too. So are Silpats!

    1. Enjoy! It’s my fave cookie dough base for basic chocolate chip cookies (the cream cheese ones you also made are great) and glad you’re a big Twix fan!

  6. Leaving the dough overnight makes a lot of difference! The first batch I made was left for 2 hours and it ended up being too soft. Is there a difference in putting 2 dozens at a time as compared to just one dozen (with a smaller baking dish)? Because I had a dozen left in the fridge and zi said I’ll just bake them the next day. It turned out a lot better.

    1. I’m not sure I fully understand what you’re asking but you can chill as much dough as you want for 5 days in the fridge before baking it. After that, if you still haven’t baked it, move it to the freezer, and that buys you another 4 mos or so. I agree that overnight chilling is superior to 2-3 hour chilling.

  7. Hi Averie,
    I made this cookies twice in the last week (once for us and once for my kids teachers) and they are AMAZING!
    I am wondering if I could share your recipe, picture and your link on the site I work for
    You would get complete credit and we would send readers your way.
    It is one of the number one math sites for children and teachers.
    We recommend cooking with children as a way to further math skills.

    1. Thanks for trying them and glad you loved them! I actually made a batch of them this weekend, too. Great minds think alike :)

  8. This recipe looks absolutley – I’m going to send my readers over here (aka linking up) for it :D

    All the best

  9. Is the dough supposed to be super gooey? It was really sticky and they spread out a lot even though I chilled the dough for 5 hours. Any idea what I might have done wrong? Or could do differently next time?

    1. No it’s not supposed to be super gooey or super sticky, at all. Are you sure you measured 2 cups flour? If you’re 100% sure you did measure 2 full cups, I would say increase the flour in 1 tbsp increments next time. Sounds like you were 2 to 4 tbsp short on flour.

      Also, I swear by King Arthur all-purpose flour. It’s $5.49 a bag compared to $3 a bag for storebrand here in CA but honestly, it performs like no other flour. It has a slightly higher protein content than other flours, which gives baked goods more structure. Usually cheaper flour is ‘weaker’ and things will be more prone to falling/flattening.

      Double-check your flour measurement, add a bit more if needed, and switch to higher quality flour are my 3 pieces of advice.

  10. Hi Averie – I’m attempting to make these cookies because your photos make them look so appetizing! If I’m going to chill the dough for a few days, should I wait to add the Twix? Or should I add the Twix in now? I wasn’t sure if the Twix cookie would get soft or not! Thanks in advance :)

    1. Add the Twix with the dough as written in the recipe. 3 to 5 days chill time isn’t going to really effect it because the chocolate coating on the Twix is quite impervious to getting soggy. Plus, you’re baking it so it dries out anyway. Just make as written, chill dough, enjoy! LMK how they turn out!

  11. Those look AMAZING!!!
    I have all my ingredients ready to make these cookies, unfortunately when I opened my new pack of light brown sugar, I realized that I accidentally purchased the wrong sugar, the brown sugar is in crystal form, and not soft…..If I do use it, would it give me the same result for the cookies, and if not should I just pulse the sugar in the food processor?
    Also another question, can I substitute margarine for butter, what difference would it make?
    Thanks! :)

    1. Do not substitute margarine for butter; you will not get the same results and the cookies will not bake the same way or taste the same way.

      As for the sugar, I don’t know exactly what you bought, so don’t know if it will work.

      I strongly encourage making the recipe as written until you know how things should look before you start making adaptations. I just want you to have success – and know if you make it as written, you will.

  12. Made these the other day. I liked them, but my family thought they were too sweet. I thought the cookies tasted like B&J cookie dough ice cream :)~

    1. Well when you bake candy bars into chocolate chip cookies, yes, they will be sweet. However, I think standard birthday cake frosting from the bakery is sweeter than the cookies.

      Glad you liked them though! Anything that tastes like ice cream is good!

  13. Okay. I need these like, now. amazing!!! Can’t wait to try these. I know my husband will die once he tastes one!

  14. I have completely been wanting to put twix in something or the other for ages, and here you’ve gone and done it! Perfect! Can’t wait to make these – they look delicious :-)

  15. If we’re going to talk about stunning cookies, we are going to talk about these! Twix in a cookie? Genius and I want these right now ;)


  16. Oh man Averie, these look divine. I will definitely be making a batch of these soon. YUM

  17. These look very good indeed. I love adaptations of the good classics….definitely need to try these.


  18. twix + cookies = AWWWesome….and love how you say you strategically placed the twix pieces….love that…to get the perfect bite! 8 days till your cookbook!!!!

  19. Twix is hands down my favorite candy bar. Such a great idea to use them in cookies! I am not sure I would be able to save any for other people though. But I am not going to let that stop me from making them, LOL!

  20. These look awesome Averie! Twix used to be my absolute favorite candy bar, and even though my taste buds have developed since then, I have a feeling putting them in a homemade cookie would still be right up my ally. I totally agree with all your cookie tips, and I do the same thing baking half a dozen at a time. Freshly-baked cookies are always best!

    1. I love just baking what I know we need that day. Plus, it’s automatic portion control if you only have 6 baked at once :)

  21. Twix Bars are one of my very favorite chocolate bars, so naturally, I would be all over these cookies. That oozy caramel looks mouthwatering!

  22. I love twix despite a bad experience I had with one…

    I’m glad I still love them because these cookies are calling my name! I have yet to try your chocolate chip cookie and I think I’m finally going to give it a go.

  23. *Love* (What’s not to love about these cookies?!)
    After all the cookie recipes I’ve made, I still second guess myself when it comes to pulling cookies out when they look slightly under-baked. (Maybe I should just turn off the oven light.) :D

    1. Thanks for pinning! And yes, I second guess myself, too. I think it’s normal b/c they can look sooo under-done but in 10 mins, miraculously firm up!

  24. There are cookies INSIDE your cookies!! I LOVE Twix because it’s candy and cookie all in one, and this just makes it 5 billion times better!

  25. You just can’t go wrong with this cookie recipe! And it is the perfect dough for just about any add-in. I love Snickers and chocolate chip cookies together and these are right up my alley as well. Twix bars were one of the best growing up. I always loved that you got two bars in the package! The crunchy shortbread is the perfect contrast to the soft and chewy cookie dough. I love these Averie!

    1. Knowing you love Snickers and Milky Way and caramel in general, I figured you’d be a Twix girl, too. And yes, the crunchy shortbread is the perfect contrast to the soft and chewy cookie dough. I was hoping it would be, and it turned out as planned!

  26. Love these Averie! Can’t wait to try them!! Thanks for mentioning the dangers of over-baking, I’ve fallen victim to it a few times and you end up with rock-like inedible cookies!! :( I’ll definitely try this recipe out soon! :) Thanks for sharing! x

  27. Never really been a huge cookie fan, but these may just get me hooked. Thanks for sharing.

  28. Twix bars are one of our favorites in my house and I try to only buy them during the month of October, lol! These would be so wonderful and dangerous at the same time!

  29. Ahhhhhhh, you and your candy bar cookies. I can’t handle all this amazingness! Brain is overloaded with awesome.

  30. I seriously need to make this fabulous cookie base of yours soon-there are so many options!

  31. Mmm! Love Twix Bars! Averie, I may never leave this page dripping with ooey-gooey wicked goodness! I’ve been so good for so long on my blog (offering paleo recipes), you have inspired me to get a little more wicked (in a good way, of course)! xo

  32. I just started adding cornstarch to my cookies and I can’t believe I waited so long- it makes the softest cookies ever! I love the idea of adding candy bars to cookies!

  33. These look dangerous and impossible to resist! I’ll have to try them out sometime!

  34. Twix is my weakness… And now you gave me a reason to put it in a cookie. I am in trouble! :) Pinning!

  35. My boys know every Halloween that Mom gets the Twix bars. They’re probably my favorite candy bar…or they’re in the top 5. These cookies look so delicious! I know I would love them.

  36. You’re so right about that one, Averie…can not have enough candy bars. I love to bake with candy bars…and these are the perfect cookies! (=

  37. Me and my family are crazy for Twix,,,this recipe is now on my “to make” list for sure!

  38. I love soft and chewy dough, so these sound magical. Your pictures are beautiful, I bet these taste amazing.

  39. I’ve used this cookie base and I bet twix would be incredible in them! You are so right about making sure your candies are on top – I learned the hard way!

    1. Oh wow – yeah, you have to be careful otherwise yes, they kind of sizzle away on the baking sheet!

  40. Gaaaah! These would be so dangerous to have around (although I’d probably bring them into work for my coworkers ;)). I looove the pieces of Twix that you can see in each cookie!!

  41. I still need to try cornstarch in cookies. These look fabulous. Twix are one of my favorites…especially the PB ones!

  42. These look delicious Averie, love the fact that the caramel goes all gooey :-) I’ve tried using cornstarch in my cookies before, but only used 1 tsp and it didn’t really have any effect, so I’m going to up the amount and see how it goes!

    1. The 2 tsp works like a charm with all the other ratios. Don’t change a thing…these are PERFECT! :)

  43. I’ve made your snickers bar cookies before and LOVED them! I guess I must have skipped to the end, because I don’t remember reading the importance of cornstarch! That must explain why they were so good!! I’m definitely going to give these a try, Averie. Love them!

    1. I didn’t know you tried the Snickers cookies but glad you did – and glad they were a hit! These are just as good (the same) but with Twix!

      1. I didn’t blog about them or anything…I think we ate them too fast, haha.

      2. LOL – those are the best kinds of recipes. The ones you don’t have to be too picky or obsess over :)

  44. Those look amazing!! I am going to be making some soon! I love twix and milky way!! Yummy! I like the addition of the corn starch, great tip! And I too like my cookies soft and gooey and a little underbaked. Maybe I could send along a mars candy bar care package from my office to make sure you keep baking up such yummy treats!!

    1. You are too sweet :) I wish we lived closer. I have that I could unload on you and the fam! Have a wonderful holiday!

  45. All of that melty caramel looks great. Yay for warm cookies, especially ones with caramel!

  46. Gotta love adding candy to cookies! It always makes for on heck of a cookie and these look perfect!
    Happy Memorial Day!

  47. Another great version of your stellar CCC dough! I think I would love anything stuffed in there. I had some mint M&M’s recently and thought those would be good in one of your chocolate cookies…and you have some yummy ones to choose from in that category too!

  48. Love this idea! Twix bars are some of my favorites so naturally I know that I would adore these cookies!

  49. That’s awesome bars, I love to eat them. I appreciate you on sharing such delicious recopies.

  50. These cookies look like so much fun and I love that they’re so adaptable for your candy bar preferences! I’ve been experimenting with cornstarch in my dough recently. It makes cookies crazy soft!

  51. Twix is my favorite bar as well, just next to Snickers :)

  52. My husband loves Twix. He would flip if I made some of these cookies. Of course it would have to be super secret until the cookie were ready. If he got wind of having Twix in the house they would be gone.
