Chewy Chocolate Chip Cookies

Pinned over 3 million times, these super soft and chewy chocolate chip cookies are the most popular cookie recipe on my website. Melted butter, more brown sugar than white sugar, and an extra egg yolk guarantee the chewiest chocolate chip cookie texture. Big chocolate chunks promise chocolate in every single bite. The flavor and texture of these cookies is unparalleled by any other recipe. No mixer required!

There are hundreds of chocolate chip cookies recipes out there. Everyone has their favorite! But, in my mind, this recipe really stands out. These chewy chocolate chip cookies are:

  • The chewiest of chewy and the softest of soft!
  • Extra thick.
  • Bakery style with an under-baked center.
  • Exploding with chocolate!

Warning: these chocolate chip cookies require a tall glass of milk. Watch me make them from start to finish in my own kitchen:

I tested today’s cookie recipe over and over again to make sure they’re absolutely perfect before sharing the recipe. I still have a big space in my heart (and tastebuds) for my Soft Chocolate Chip Cookies. They’re one of the most popular recipes on my website! Today’s recipe is similar, but I increased the chewy factor.

How to Make Chewy Chocolate Chip Cookies

The cookie dough is made from standard ingredients: flour, leavener, salt, sugar, butter, egg, & vanilla. It’s the ratios of those ingredients that make this recipe stand out from the rest. Mix 2 and 1/4  cups of flour with 1 teaspoon of baking soda, 1/2 teaspoon of salt, and my favorite: cornstarch. I use 1 and 1/2 teaspoons of cornstarch in this recipe.

  • Why cornstarch? Cornstarch gives the cookies that ultra soft consistency we all know and love. Plus, it helps keep the cookies beautifully thick.

Use melted butter in this chocolate chip cookie recipe. Most of the cookies on my website call for creaming softened butter with the sugars. Chewy chocolate chip cookies require melted butter.

  • Why melted butter? Melted butter produces the chewiest cookies. It can, however, make your baked cookie greasy, so I made sure there is enough flour to avoid that from happening.

Since you are using melted butter, you don’t need a mixer for this cookie recipe.

Use More Brown Sugar

Use a mix of brown sugar and white granulated sugar in your chocolate chip cookies. I prefer more brown sugar than white granulated sugar because the moisture in brown sugar promises an extra soft and chewy baked cookie. White granulated sugar is still necessary though. It’s dry and helps the cookies spread. A little bit of spread is a good thing.

Extra Egg Yolk

Another way to promise a super chewy chocolate chip cookie is to use an extra egg yolk. The extra egg yolk adds richness, soft tenderness, and binds the dough. You will need 1 egg and 1 egg yolk. You can freeze the extra egg white in a ziplock bag for up to 1 month or use it to make my Skinny Chocolate Peanut Butter Cupcakes. 🙂

The dough will be soft and the chocolate chunks may not stick because of the melted butter. Just keep stirring it; I promise it will come together.

The most important step is next.

Chill the Chocolate Chip Cookie Dough

Chilling the cookie dough is so important! Unless you want the cookies to spread into a massive cookie puddle, chilling the dough is mandatory for this cookie recipe. It allows the ingredients to settle together after the mixing stage but most importantly: cold dough results in thicker cookies. Cover the cookie dough and chill the dough for at least 2-3 hours and even up to 3-4 days. After chilling, let your cookie dough sit at room temperature for 10 minutes before rolling into balls.

After chilling, sometimes I roll the cookie dough into balls and freeze them in a large zipped-top bag. Then I bake them straight from the freezer, keeping them in the oven for an extra minute. This way you can have just one of two cookies whenever you want!

These cookies are huge–about 3 Tablespoons of dough is rolled to make one cookie. The batch only makes about 16 cookies since you will be rolling them so large. Feel free to make the cookies smaller (about 2 Tablespoons of dough per cookie) instead. If you do that, be sure to reduce the baking time by a couple minutes.

When you remove the cookie dough from the refrigerator after chilling, the dough will be slightly crumbly. The warmth of your hands rolling it will make it stay intact. Roll the cookie dough balls taller, rather than wide as I discussed and showed in my cake batter chocolate chip cookies recipe. This little tried-and-true trick will result in thicker cookies. I do it for every single cookie I bake.

Secrets to Thick, Soft, & Chewy Chocolate Chip Cookies

  • Underbaked cookies are the secret to softness.
  • Using cornstarch in the dough is another secret to softness, as well as the secret to thickness.
  • Using more brown sugar than white sugar results in a moister, softer cookie.
  • Adding an extra egg yolk increases chewiness.
  • Rolling the cookie dough balls to be taller than wider increases thickness.
  • Using melted butter (and slightly more flour) increases chewiness.
  • Chilling the dough results in a thicker cookie.

Pinned over 3 million times, these super soft and chewy chocolate chip cookies are the most popular cookie recipe on my website. Melted butter, 1 extra egg yolk, and more brown sugar than white sugar guarantee the chewiest chocolate chip cookie texture. Chilling the cookie dough is imperative. No mixer required! 


  • 2 and 1/4 cups (280g) all-purpose flour (spoon & leveled)
  • 1 teaspoon baking soda
  • 1 and 1/2 teaspoons cornstarch*
  • 1/2 teaspoon salt
  • 3/4 cup (1.5 sticks or 170g) unsalted butter, melted & slightly cooled*
  • 3/4 cup (150g) packed light or dark brown sugar
  • 1/2 cup (100g) granulated sugar
  • 1 large egg + 1 egg yolk, at room temperature
  • 2 teaspoons pure vanilla extract
  • 1 and 1/4 cups (225g) semi-sweet chocolate chips or chocolate chunks


  1. Whisk the flour, baking soda, cornstarch, and salt together in a large bowl. Set aside.
  2. In a medium bowl, whisk the melted butter, brown sugar, and granulated sugar together until no brown sugar lumps remain. Whisk in the egg, then the egg yolk. Finally, whisk in the vanilla extract. Pour the wet ingredients into the dry ingredients and mix together with a large spoon or rubber spatula. The dough will be very soft, yet thick. Fold in the chocolate chunks. They may not stick to the dough because of the melted butter, but do your best to combine them. Cover the dough and chill in the refrigerator for 2-3 hours or up to 3-4 days. Chilling is mandatory. I highly recommend chilling the cookie dough overnight for less spreading.
  3. Take the dough out of the refrigerator and allow to slightly soften at room temperature for 10 minutes.
  4. Preheat oven to 325°F (163°C). Line two large baking sheets with parchment paper or silicone baking mats. (Always recommended for cookies.) Set aside.
  5. Roll the dough into balls, about 3 Tablespoons of dough each. The dough will be crumbly, but the warmth of your hands will help the balls stay together. Roll the cookie dough balls to be taller rather than wide, to ensure the cookies will bake up to be thick. See this post for more detail and a photo. Place 8 balls of dough onto each cookie sheet. Press a few more chocolate chips/chunks on top of the dough balls for looks, if desired.
  6. Bake the cookies for 12-13 minutes. The cookies will look very soft and underbaked. They will continue to bake on the cookie sheet. Allow to cool on the cookie sheet for 10 minutes before transferring to a wire rack to cool completely.
  7. Cookies stay fresh covered at room temperature for up to 1 week.


  1. Make Ahead & Freezing Instructions: You can make the cookie dough and chill it in the refrigerator for up to 2-3 days. Allow to come to room temperature then continue with step 4. 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. Cornstarch: If you don’t have cornstarch or don’t want to use it, simply leave it out. The cookies are still very soft.
  3. Butter: Salted butter can be used instead. Reduce salt in the cookie dough to 1/4 teaspoon.
  4. Room temperature egg + egg yolk are best. Typically, if a recipe calls for room temperature or melted butter, it’s in good practice to use room temperature eggs as well. To bring eggs to room temperature quickly, simply place the whole eggs into a glass of warm water for 5 minutes. What to do with the extra egg white? Make these or these.

Chewy Chocolate Chunk Cookies have been pinned on Pinterest over 1 MILLION times. My most popular recipe!


  1. I’m so intrigued, Sally! I’ve always had such a hard time when a cookie recipe calls for melted butter. Somehow the cookies always spread and are super thin and crunchy. Not my type of cookie at all! But I guess adding extra flour helps to avoid that? None of your recipes have ever failed me, so I have no doubt that this is a brilliant trick that I will soon use all of the time (just like I always add cornstarch and refrigerate my dough now, thanks to your wonderful tips in previous posts!).

  2. I was reading this at work today and I must say, I really really enjoy reading your reasonings behind everything you do to a baked good. Like why you did this instead of this or why this ingredient works best and what it does. It’s SO interesting and it’s something I’d NEVER read or study out of like a textbook or anything..but your blog & the way you explain it? I’d read it over and over again. I feel like I LEARN something new each time I go through a recipe of yours. These cookies look like pillows. Fluffy cloud pillows. Another amazing job, Sally! 🙂 you’re obviously writing a cookbook for a reason! You know everything about baking!!

    1. Wow, Julie! Thanks for all the kind words! Growing up baking with my mom and grandmom has taught me well. Lots of mistakes have also helped along the way. Thanks again!

  3. These are amazing Sally! I love that you melted the butter. That’s my favorite way to make a chocolate chip cookie!

  4. These look so amazing. I love that you explain everything as you go along and I don’t mind all the text at all! In fact, the baking tips are really helpful. Thanks!

  5. Ok, first I love the disclaimer at the beging of the post!! That is the cutest thing ever!! Haha.
    And girl I love your text and your cookies!! You must of worked so hard at perfecting these!! They look killer!! Oh an I always underbake my cookies!! The doughier the better!!
    You are so awesome at explaining everything to!! Such detail, it is a amazing!! Your cookbook is going to be awesome!
    Seriously, you are genius!!

    1. haha thanks Tieghan. I’ve gotten slack before about writing too much text, but sometimes it’s important to explain so that everyone can learn!

  6. Oh my goodness, these are THE BEST looking chocolate chip cookies I have ever seen! You can just tell that they are the perfect texture! Also, I always love your thorough explanations! It makes your wonderful recipes foolproof!

  7. I love that you used melted butter. I like using brown butter that is still melted. Your post was so thought out and I enjoyed all the words!! I loved when you mentioned that the chocolate wont stick to the dough- I was totally reading it/seeing it in my head. The chocolate definitely does not stick, but the dough tastes divine!

    1. Melted butter is sometimes tricky, you have to have the right amount of flour to soak it all up but not so much that it will make your cookies dry. The cornstarch and baking soda alleviate that though. Thanks!

  8. Taste testing 5 batches of chocolate chip cookies sounds like such a tough job! Especially chewy, gooey ones. 🙂 Thanks for making sure this recipe turned out so good. As soon as I can eat chocolate again, I will be making these!

  9. Sally – all that work totally paid off – even in the photos these look so soft and chewy that I want to reach through the screen and pluck one out. This is absolutely the texture I want in all my cookies. A-ma-zing!

  10. Who eats all the batches that you make from testing them over and over again?! Lol cause I personally wouldn’t be able to resist that many cookies around me. I’d go into a sugar coma, for sure!

  11. Hi Sally

    In your headnotes you mentioned that you used chocolate chunks and mini chocolate chips did the combination equal one cup of chips or a little more chips.

  12. I always feel like I learn so much from your posts about baking! Soft and chewy cookies are totally the way to go!

  13. So, can your second book be all baking tips and scientific facts? I usually hate reading about the food on food blogs, but I always read every word you write–everything had a purpose, and I feel like I’m going to school in the best way possible! Also, umm, yum.

  14. Love the info overload here–Food Network needs to get an infomercial channel running and then beg you to run it. I love all the tips; next time my friends ask me how I managed to make such awesome chewy thick cookies, I’m glad I’ll be able to explain it! And that’s more than I can say for recipes from most blogs. <3

    1. Thanks Ala – what a nice comment to read this morning! Being on the food network! What an honor that would be. 🙂

  15. I have been developing some recipes usign cornstarch and I am so pleased with the results. Can’t wait to share! These cookies are freaking awesome Sally 🙂

  16. Sally, thanks for the awesome tips on keep these cookies soft and thick!! There is nothing worse than a flat cookie. Every cookie recipe I’ve tried of yours always turns out so good!!

  17. Yum! Thanks for all the inside info on how to make cookies soft! And I love that this recipe doesn’t need a mixer! Although once I win this Kitchenaid giveaway, I guess that won’t be a problem anymore, huh? 😉

  18. Darn it! I ran out of eggs AND chocolate (all types, chocolate chips, cooking chocolate, kisses, bars) OMG I dont even have oreos in the kitchen!!!! How on earth and when did that happen!!!!!????
    I am horrified o_o

    Anyways, will do grocery shopping, bake these cookies, eat them all and then Ill tell you how amazing they were 😀

    1. Sounds like a plan! And that’s happened to me before, too. Running out of chocolate chips — I had to run to the store right away!

      1. Sally, remember when I told you Ill go shopping and bake these beauties then tell you how it all went?
        First, I also discovered that I had no nutella or PB in the kitchen, horrified seemed like a small word back then. Anyways, my pantry is full of goodies. And i did start baking! Ive been baking all week!!
        I made your death by chocolate cookies for my sister to take to school, i made the gigantic version for myself, twice, in a row, on the same day. And both recipes proved deadly and sinful. They were hearty and oh-so-delicious!! Instead of pb chips I used milk chocolate chunks with semisweet chips. They were like brownies, but better!!!!
        Then i baked brownies, that failed.
        I baked your Perfect chocolate chip cookies. THE chocolate chip cookies. And i know why you call them perfect, because tat is what they are. Enough
        2 days back I baked the snickerdoodle pillows, the ultimate chewy cinnamony cookie heaven. I will comment there about them.

        But still I havent tried these cookies!!!!!!

      2. You have made a few of my favorite recipes recently. 🙂 I love those chocolate chip cookies. Now you have to try these next!

      3. Baked them. Loved them. Shared them. Baked them again. Gave them away. Planning to bake them a third time.
        This is the best cookie recipe ever!!!!!!
        Theyre so delicious and goood and oh so easy!!!
        I refrigerated the first batch for only 30 mins because my brother and his wife came over earlier than expected, and all 16 cookies disappeared before they even cooled down completely!! On spot i made the second batch, kept them in the fridge for 2 hrs and baked them for my brother to take. His wife just texted me saying these were even better! Not sure whether it was because it was refrigerated longer or because they ate them cool. Lol whatever the reason this recipe just became THE recipe for me!!!
        Thank youu thank you thank you!!!

  19. Wow! Chewy cookies are the best! I have the same ingredients on my cookie recipe but different ratios. I’m going to try yours. I also always add ground flaxseed meal and I have substituted whole wheat pastry flour + whole wheat bread flour instead of AP to make it more healthy, because my Husband loves chewy choco chip cookies and he’s also trying to loose weight.

  20. I love all the cookie science Sally 🙂 I tend to find that my cookie recipes that use cocoa tend to bake up thicker than without, I’m wondering if it has a similar effect to cornstarch?

  21. Made your Andes cookies last week, trying these out this week! May revisit the Andes cookies again this week as well since they go so INSANELY well with a cup of coffee! Your recipes are awesome! Please keep them coming! Can’t wait for your cook book! My daughter and I are bake-aholics and usually bake nothing but cookies! So glad I started using pinterest and found your posts! Already looking into a cookie recipe to try for next week!

    1. I have to try those andes mint cookies with coffee. 🙂 So glad you love to bake so much. And Pinterest. What would we do without it?!
