I have no shortage of chocolate chip cookie recipes here on my site. I hope you have made a few of them, but if you haven’t, todays recipe is a good place to start!

They are very similar to the famous Levain Chocolate Chip Cookies in NYC, so if you’re a fan of their gooey, giant cookies, these will be right up your alley!
Whether you are a fan of nuts in your cookies or not, this is THE cookie recipe for you if you like THICK cookies! I’m going to show you the super easy tricks to making the thickest cookies ever!

How To Make THICK Cookies!
Ok, I am going to share a few tricks with you today that are super easy, and kind of life-changing if you are into thick cookies. This chocolate chip cookie recipe might end up being your most favorite ever because it’s pretty perfect if you are in love with giant cookies like I am! Sure, I really do enjoy a crispy cookie from time to time, but when I crave chocolate chip cookies, the cozy, buttery, melty chocolate is what I’m after. And these beauties deliver…BIG TIME!
#1 – Increase Your Oven Temp!
So most chocolate chip cookie recipes call for you to bake them at 350°F. BUT let’s think about that…I’ve tested cookie recipes at different temps and have found the higher the oven temp, the less the cookies spread. Makes sense.
AND it’s an amazing trick to keeping your cookies soft on the inside, because since you’re baking them at a higher temp, the outsides get browned more quickly, leaving the insides slightly under-baked. Kind of like searing your cookie! You do it for meat, so I thought, why not try the same idea for cookies. Turns out, it works PERFECTLY!
#2 – Use COLD Butter
You can achieve the same effect by chilling your dough, so that’s always an option, of course. BUT if you don’t want to wait for your dough to chill, use cold butter and it will aid in preventing the cookies from spreading as much! Of course, chilling the dough helps deepen the flavor as well, so that’s a benefit of that, but I’m just here to tell you it isn’t necessary!
#3 – Cornstarch
Cornstarch is a thickening agent, so it makes sense to add it to cookie dough in small amounts when you would like your cookies to be thicker. And while I think cornstarch does aid in making your cookie slightly thicker, what I find it does best is leave the insides of your cookie more tender by softening the proteins in the flour. So you get a slight crisp on the outside of your cookie while being soft on the inside!
#4 – A Little Bit More Flour
This is a fine line for sure…too much flour and you’ll end up with cakey, dry cookies, but a little bit more paired with the higher bake temp = perfectly thick cookies!

Can I Freeze These Chocolate Chip Walnut Cookies?
Yes!! Like I said above, this recipe doesn’t have to be chilled before you bake them, BUT you can absolutely freeze the dough and save it for later…OR you can freeze your cookies after they’ve been baked! Here’s how:
Freezing the Dough
Simply prepare the recipe as written through step #6. DOn’t worry about spacing the dough out on the baking sheet, you can place the portioned dough close together to fit all your scoops on one baking sheet.
Then flash freeze all the dough balls for 45-ish minutes, until they are solid. Then place the dough balls into a large zip-top bag and freeze for up to 30 days.
To bake the dough you don’t have to worry about thawing the dough out, but I would reduce the baking temp to 375°F if you are baking them from frozen!
Freezing the Already Baked Cookies
If you end up with too many cookies, so ahead and make sure they are cooled completely, and place them in a large zip-top bag or a plastic container and freeze them for up to 30 days!
Thaw them at room temperature and you can even pop them back into a 350°F oven for 3 minutes to heat them back up!

Do You HAVE To Use Walnuts In This Cookie Recipe?
Nope! You really don’t. I am actually not a huge fan of nuts in my cookies, so I have made these with AND without the nuts! You can even decrease the amount of nuts in the recipe to 1 cup if you want to start slowly! BUT if you’re a fan of nuts, you can also get creative with your options:
- Pecans. This is an easy swap out!
- Pistachios. Chop them up to add another layer of flavor to your cookies!
- Peanuts. This could be really good!
- Macadamia Nuts. Swap out the chocolate for white chocolate and you could have an extra thick version of my White Chocolate Macadamia Nut Cookies!

Hi, how are you? Is it normal that my chocolate chips don’t melt? Whenever I make cookies I have this problem with chocolate chips, they don’t melt like yours in the picture. Maybe it’s because I freeze my cookies before baking idk! I’d like to know why or if there’s anything I can do
They are only melty like this when they are warm. They do firm back up when they’ve cooled!
If I only have brown sugar and granulated sugar, how do the amounts of sugar change?
You can just use 1 cup of light brown sugar 🙂
I just made these. The first batch came out quite thick and a bit undercooked in the middle, so increased the cooking time and squashed them flatter, for second lot. Came out perfect..big hit with the family.. Will be making these again. Easy recipe. Thank you
The cookie has a consistency which is more bread like than cookie. Although they are ok, it’s not what I was expecting. I prefer a cookie that is chewy in the middle and crisp on the edge. These were not that. The middle was more like undone and soft. They did not spread when baked just as the recipe claims. This is a relatively easy recipe to follow.
I had the exact same results and also left a two star review that seems to have disappeared. I followed the recipe perfectly and these cookies were like thick dry bread dough despite having all the amazing ingredients.
I followed the recipe exactly as written but increased the cooking time 13 min
Bottoms of cookies were Golden brown in the middle was uncooked
What type of cookie sheet did you use? And did you use parchment paper?
I followed the recipe perfectly and had the same results,would have been better off following the recipe on a bag of chocolate chips.
I did 13 mins too, and they turned out just perfect!
Bake regular till house cookies and refrigerate dough for 20-30 min (until dough is firm ball ) scoop out onto baking sheet and the cookies will be great and not flatten out . That’s it
OMG! BEST COOKIES EVER! While still warm, I brushed on a melted butter, Barbados rum, and light brown sugar drizzle. Amazing. Thank you✨
OMG that sounds amazing!!
I made these for Thanksgiving substituting dark chocolate chips. A huge hit. Everyone loved them. I’m down to my last two which is good / bad.
So soft and fluffy!! Yum!!
I softened the butter because I don’t have a mixer. I only had light brown sugar, so I used 1 cup of light brown sugar (instead of 1/2), and they still turned out delicious! I only used 1.5 cups of chocolate chips and 1.5 cup walnuts.
Trying it now. I will refrigerate the 3 dozens yield overnight. Since it’s smaller and has longer sitting time, how do I adjust the baking time and temperature?
BEST COOKIES EVER!! I have tried so many recipes that say their thick cookies and they never are. I don’t like the flat, thin cookies. My 5 year old grandson loves to bake with me. We had just baked a batch of cookies the day before so when he saw I had made these without him he was a little bummed. After he had one bite of this cookie he was all thumbs up and smiles. When he came over the next day he immediately asked for a cookie. “Not the ones we made grandma but the one you did by yourself.” That’s a big compliment in my world.
Oh thank you so so much!! So glad you liked them!
