I was inspired to make today’s double chocolate chip swirl cookies because I love my peanut butter version. I wanted a swirled cookie that was all chocolate– this recipe is just like my peanut butter chocolate swirl cookies, but we use classic chocolate chip cookie recipes instead of a peanut butter dough.

Two Cookies in One

We’re combining two reader favorite cookie recipes into one to create today’s double chocolate chip swirl cookies:

  1. Rich and buttery soft chocolate chip cookies
  2. Indulgent chocolate white chocolate cookies (this dough is my inside out chocolate chip cookies recipe)

Best of Both Cookie Worlds:

  • No need to choose a favorite– classic chocolate chip cookies and chocolate white chocolate cookies in one
  • Melty chocolate chips and white chocolate chips
  • Super chewy and extra buttery
  • Each cookie has a beautiful, unique swirl
  • Soft-baked to perfection
  • Lots of chocolate in every bite!

How to Make Swirl Cookies

These swirl cookies might look a little complicated to make, but they couldn’t be easier. We’re simply making two cookie doughs, rolling them together, and baking. Let’s quickly review the steps so you understand the process before you begin:

  1. Make the chocolate white chocolate cookie dough.
  2. Make the chocolate chip cookie dough.
  3. Chill the cookie doughs. We’ll combine them next, so refrigerate them separately. I recommend chilling the dough for at least 3-4 hours for thicker cookies (as pictured).
  4. Roll each cookie dough into balls. Use about 1.5 Tablespoons of dough for each. Combine 1 chocolate white chocolate cookie dough ball with 1 chocolate chip cookie dough ball– roll these two together with your hands into 1 large cookie dough ball (about 3 Tablespoons of dough total).
  5. Bake. I always recommend baking cookies until the edges appear set. These should take at least 11-12 minutes.

Chilling Cookie Dough is Imperative

Chilling the cookie dough is a must for this recipe. Why? It helps prevent spreading.

For these double chocolate chip swirl cookies, I recommend chilling the cookie dough for at least 3-4 hours. Chilling cookie dough helps prevent excess spreading. The colder the dough, the less the cookies will over-spread into greasy puddles. Chilling cookie dough not only ensures less spreading, but heightened flavor as well. All of the flavors in your cookie recipe will mingle with one another during the chill time. It’s glorious!

These irresistible double chocolate chip swirl cookies combine soft chocolate chip cookies and chocolate white chocolate cookies in one. Make sure you chill the cookie doughs as instructed. See recipe notes for freezing instructions.


Chocolate White Chocolate Cookie Dough

  • 1/2 cup (115g) unsalted butter, softened to room temperature
  • 1/2 cup (100g) granulated sugar
  • 1/2 cup (100g) packed light or dark brown sugar
  • 1 large egg*
  • 1 teaspoon pure vanilla extract
  • 1 cup (125g) all-purpose flour (spoon & leveled)
  • 1/2 cup + 2 Tablespoons (51g) unsweetened cocoa powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2 Tablespoons (30ml) milk*
  • 1 cup + 2 Tablespoons (202g) white chocolate chips

Chocolate Chip Cookie Dough

  • 3/4 cup (170g) unsalted butter, softened to room temperature
  • 3/4 cup (150g) light or dark brown sugar
  • 1/4 cup (50g) granulated sugar
  • 1 large egg*
  • 2 teaspoons pure vanilla extract
  • 2 cups (250g) all-purpose flour (spoon & leveled)
  • 2 teaspoons cornstarch (aka cornflour)
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup + 2 Tablespoons (202g) semi-sweet chocolate chips


  1. Make the chocolate cookie dough: Cream the butter and sugars together with a hand or stand mixer fitted with a paddle attachment on medium speed until light and fluffy. Scrape down the sides and bottom as needed. Beat in the egg and vanilla on high speed until combined, scraping down the sides as needed. In a separate bowl, combine the flour, cocoa powder, baking soda, and salt. Slowly mix it into the wet ingredients on low speed. The dough will be thick. Again on low speed, mix in the milk until combined. The dough will be sticky. Fold in 1 cup of white chocolate chips.
  2. Make the chocolate chip cookie dough: Cream the butter and sugars together with a hand or stand mixer fitted with a paddle attachment on medium speed until light and fluffy. Scrape down the sides and bottom as needed. Beat in the egg and vanilla on high speed until combined, scraping down the sides as needed. In a separate bowl, combine the flour, cornstarch, baking soda, and salt. Slowly mix it into the wet ingredients on low speed. The dough will be thick. Fold in 1 cup of chocolate chips.
  3. Cover both cookie doughs with aluminum foil and chill for at least 3-4 hours or up to 3 days. Chilling is imperative; the cookies will spread into flat puddles if the cookie doughs are not chilled.
  4. Preheat oven to 350°F (177°C). Line cookie sheet with silicone baking mat or parchment paper. Measure 1.5 Tablespoons of chocolate cookie dough. Roll into a ball. Take 1.5 Tablespoons of chocolate chip cookie dough. Roll into a ball. Press the two balls together between your hands and roll them into 1 large ball. Repeat rolling for each cookie. The chocolate cookie dough is particularly sticky and will stick to your hands, so wash/wipe them after you roll each cookie. It’s important the chocolate cookie dough is chilled or else it will be even more messy.
  5. Bake the cookies for 11-12 minutes. The cookies will look very soft, puffy, and almost undone. Remove from the oven. With the remaining white chocolate and semi-sweet chocolate chips you have leftover, press a few into each cookie. (This is just for looks and not required.) Cool cookies for 10 minutes on the baking sheets before transferring to a wire rack to cool completely.
  6. Cover leftover cookies tightly and store at room temperature for up to 1 week.


  1. Make Ahead & Freezing Instructions: You can make the cookie doughs and chill them in the refrigerator for up to 3 days. Baked cookies freeze well for up to 3 months. Unbaked cookie dough balls freeze well for up to 3 months. Bake frozen cookie dough balls for an extra minute, no need to thaw. Click here for my tips and tricks on freezing cookie dough.
  2. Eggs: Room temperature egg is preferred for both cookie doughs for easy mixing. Good rule of thumb – when using room temperature butter, always use room temperature egg(s) unless otherwise specified.
  3. Milk: Any dairy or nondairy milk works.
  4. The chocolate cookies are my inside-out chocolate chip cookies and the chocolate chip cookies are my soft chocolate chip cookies. My chewy chocolate chip cookies would work as well!

  1. Can I substitute Margarine for butter? What quantity?

    1. Butter is best – I never recommend margarine for butter in my cookie recipes.

  2. Hi Sally! Just wanted to let you know that I absolutely LOVE all of your recipes and I am so glad to have found your website! You have a great gift! And also, I did the chocolate white chocolate chip cookie dough but batter didn’t come out as thick as the chocolate chip batter. Please help! Thank you again!

  3. Hi! I really want to try this recipe but quick question can I use salted butter instead of unsalted? Thanks!

    PS: Your cookie recipes are AMAZING 🙂

    1. I suggest decreasing salt by 1/4 teaspoon in both doughs if using salted butter.

  4. Hi Sally! I wanted to say I love all your recipes but I really need your help… I’m making the double chocolate chip swirl cookie again but this time the chocolate cookie dough is too soft or wet this time for some reason. I measured exactly and made sure I didn’t over pour on the flour too… Is there anything I can do or add to thicken up the dough?

    1. Hi Jenn, I suggest chilling the chocolate dough for a little longer so it becomes firmer.

  5. Just wanted to write a comment and say that I made these last night and YUM!! They turned out exactly how they look and what you said. I made the dough and chilled it for a little over 2 hrs. I followed the directs exactly (minus the room temp eggs because I completely forgot..only human). These are delicious and a huge hit at work with all the cookie critic co-workers. This is going into my “keep” recipe box!! Thanks!! YUM!

  6. So I made these yesterday and today. I messed up by adding milk to the regular choc chip dough and didn’t add enough butter, BUT they still turned out great!!! Can’t wait to give these to my family/friends! Thank you!

  7. I’ve got to say these are the best cookies I’ve ever made and I’ve made hundreds of cookies! Thank you so much for this recipe! Followed directions exactly and they turned out perfect! Now I can’t stop eating them 🙂

  8. Hi Sally
    I found your blog a few weeks ago and I haven’t stopped cooking. Not good for the waistline. I made your double chocolate swirl cookies and I found them really soft and they stuck together in the container. Not sure what I did wrong but they were super yummy still. Any suggestions? I left the dough in the fridge for 4 hours.

    1. Hi Danella! I wonder if the cookies were *too* underbaked. How do they taste? How about baking them for an additional 2 minutes.

      1. Ok thanks. They were slightly brown so I thought they would be cooked enough as my husband likes soft biscuits rather than crunchy. I will have to try again.

  9. I made these but substituted the regular chocolate chip cookies with your peanut butter cookie recipe. OMG soooo good!!! This is my new favorite site! I have yet to try a recipe on here that I haven’t liked!

  10. You are certainly right about the importance of chilling the doughs!!! My two boys and I made these in a little bit of a rush and had a huge (still delicious) chocolatey mess! We’re going to try them again next week and will be making the doughs the night day before 😉

  11. Carisa Sanchez says:

    I love this recipe! And my family loves it too. My only question is what is a serving size? I want to indulge and have 3 cookies but I dont know if that will completely kill my diet. I made them about half the size. Any suggestions about serving size would help.

  12. Hi Sally!

    I love all how creative your recipes are! I just made the cookie dough for the yin-yang cookies of yours! But in a rush i forgot to put corn starch in the white cookie dough. I noticed it was not an ingredient in the dark cookie dough. How important is it? What effect will it have on the cookies? Because my dough is already in the fridge to be chilled and so i cannot add the corn starch! Hope they turn out okay! 🙁

    1. The cornstarch just gives them that extra soft texture. The chocolate dough is already quite soft. Your cookies should be just fine though.

  13. I made this recipe for a work bake sale (raising money for a local charity), and while every other baked good took the full week to sell, these sold out within 24 hours! Everyone loved them. The recipe says to chill at least 2 hours, but listen to Sally and chill for at LEAST 4 hours. The chocolate dough is the one that really needs the chilling; I’ve waited the 2 hours and had the chocolate side of the cookie end up too flat, which looked awkward with the thicker regular dough attached to it. It is worth the extra time to chill! Delicious recipe, Sally. Your recipes are the only ones I don’t read the comments for to make sure it will turn out well!

    1. Amazing. Thank you for taking the time to report back Victoria!

  14. hi there! it was my first attempt at baking and these cookies were wonderful! one thing left me puzzled though, i ran out of the chocolate dough way faster than the chocolate chip one. is this supposed to happen, or did i do something wrong? nevertheless, the cookies were perfect. thank you for sharing this recipe 🙂

  15. Hi Sally! I made these cookies today for a family dinner and they were a hit. Everyone loved them and asked where I found the recipe. I of course told them that I found them here. These cookies were absolutely amazing and I honestly can’t get enough. I will definitely be making them for numerous occasions to come. I was just wondering, my batch was really soft and fell apart if I picked it up on only one part of the cookie, but I was afraid that if I put them in for longer that they might burn and become really crunchy. Is there any way that I can avoid this for future batches to come?

    1. Veronica– so glad these were a huge hit! I’m not surprised. If you bake the cookies for 1-2 minutes more– they won’t be crunchy. These are such soft cookies already that a little more time won’t ruin the texture BUT will help them stay intact.

  16. When made your cake batter chocolate chip cookies (they were AMAZING) I made the dough on a Saturday night and baked the cookies the following day. Your notes said that if you chilled the dough for longer than two hours I needed to roll the dough into balls at the two hour mark. Does that apply to this recipe as well? Thanks! 🙂

  17. Omg… These were so delicious and beyond fun to make! I was getting bored of just the classic choco chip cookie so this was definitely the best of both worlds. One helpful tip is to remember to take caution in reading the separate cookie recipes carefully as to not mix them up.

    I got so many compliments on these and I can literally not stop eating them! Yum!!!

  18. I made these and my chocolate chip cookie dough, dough is super crumbly. Every time I attempt to roll it into a ball it just crumbles  What did I do wrong? 

  19. Hi Sally! I am planning on making two batches of this recipe to give my classmates this Christmas. I just have a question. Will the cookies still be fresh two days after being baked? The only time I can make them is two days before the Christmas party.

    1. Definitely! Just keep them covered tightly at room temperature.

  20. I have made these cookies before and they are a huge hit!

    Am I able to double the recipe or do I need to make them twice?

    I looked through the comments but didn’t see this question. Apologies if I missed it

    1. Hi Tara! Yes, you can certainly double them 🙂

  21. Hey Sally
    Can I halve this recipe?
    Don’t have enough chocolate chips.

    1. Sure can!

  22. aniqua Chowdhury says:

    Do I need to chill the cookie dough in aluminum/tinfoil or can I just keep ’em in a bowl covered in plastic wrap? (I just ran out!) Also, can you send me a link of the type of silicone baking mats you use? I want to purchase some. Thanks!

    1. In a bowl covered with plastic wrap is fine! These are the silicone mats that I use:

  23. When do you add cornstarch?

  24. These were wonderful-I followed the instructions and had great results! ONE QUESTION: can I make these smaller? (They made huge cookies!) What should the bake time be for the smaller cookies?

    1. I’m so glad you enjoyed them, Melissa! You can certainly make them smaller – try one TBS of each dough instead of 1.5. The bake time will be slightly shorter – you will know they are done when the edges just start to brown and the center still looks soft.

      1. Wonderful! Thank you, Sally!

    2. They are divine. Kinda fiddly and the dark choc batter is much stickier than the plain so u get filthy but totally worth the fuss. They look amazing when cooked they were a huge success!

  25. I have made these many times for a number of years there DELICIOUS! Everytime I pick up white chips the boyfriend asks if I’m making my yin yang cookies.

  26. do they make 32 full cookies or 16 cookies since they are two cookies in one and about how big around are they

  27. Andrea Sans. says:

    These are delicious! Very soft and chocolatey. Needed a fun activity for my son and I one afternoon this weekend and making two cookies into 1 was perfect for us.

  28. I made these last night and the entire family loved them. I baked some last night and some today. They turned out amazing. Love the fudginess of the chocolate cookie. I will be making these again for sure.

    Note: I did use Bob’s Mill 1:1 Gluten Free flour instead of regular flour. Otherwise, I followed the recipe and they were delicious.

  29. These are great

  30. Hi Sally. I would like to know what type of milk you use for this recipe?

    1. Trina @ Sally's Baking Addiction says:

      Hi Shae, any dairy or nondairy milk works – we usually use 2% milk.
