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! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts. It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

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… Read more »

Hello! These are exceptionally tasty.. and what’s more, I get the feeling I can count on them turning out well every time. Thank you, Shelley!

This is a keeper!!! My last batch of cookies were buttery but flat before I came across this recipe. I had allowed my butter to soften but put my butter in the freezer to quickly hardened but not too hard per Shelly’s recipe. I believe it made all the difference and my cookies came out really good!!! I do NOT believe in changing another persons recipe, but my husband enjoys walnuts and oatmeal in his cookies and I added a cup of each in addition to the chocolate chips. Shelly thank you so much for the tip…any ideas why the… Read more »

Hi? I would love to try this recipe, is there a way to cut down the sugar?

August 22, 2020 4:29 pm

These are my favorite chocolate chip cookies! They are think and chewy, just like the bakery 🙂 So delicious! Thank you for this recipe and the tips!

I had a not good experience with this recipe. They basically held their ball shape so much and I ended up with something between a cakey and biscuit texture. I’m willing to try it again but I’ve never had this problem with cookies before

August 10, 2020 3:49 pm

These are great, but you really only need half the amount of chocolate chips. This got enough sugar to kill a damn horse .

July 18, 2020 4:52 pm

Best cookies ever! Everyone wants me to make more.

July 14, 2020 5:45 pm

Hi. I was wondering if there was a way to make more on the crispier side?

July 11, 2020 3:32 pm

Hi!! I only have light brown sugar… can i use coconut sugar to substitute for dark brown sugar or should I just light brown sugar in place of dark brown sugar?

June 27, 2020 3:32 pm

Yummy! I just made this recipe and it was easy and tasty! I had never used corn starch in cookies.

June 25, 2020 1:35 pm

I used a rather large ice cream scoop. The recipe then made 18. The cookies are delicious and look like you bought them at the bakery! This is now my go to recipe for chocolate chip cookies!

These were amazing! I’m at high altitude and decreased each sugar by 1 tablespoon, baking soda to 3/8 teaspoon and added 3 tablespoons of water. Cookies are magic in your mouth. Thank you for delicious recipe.
