Forget those flat, sad little cookies you bake by accident! We are talking about substantial, glorious, bakery-style treats that actually look like they belong behind a glass case downtown. I knew I had found pure magic years ago when I first bit into one of those famous cookies in Brooklyn. Wow, the huge chunks of chocolate, the satisfying crunch of walnuts—it was a revelation! My journey to recreate those Thick Levain Style Chocolate Chip Walnut Cookies back home was a mission, especially after I started dealing with my own gluten sensitivities. Trust me; pouring my heart into recreating that exact feel and flavor was worth every test batch. I’m Elena Brown, and I’m going to show you how to bring that giant cookie perfection right to your own kitchen. You can find a fun take on the original inspiration right here, but what we’re making is uniquely ours!
Why You Will Love These Thick Levain Style Chocolate Chip Walnut Cookies
I promise you, once you make these, you’ll never go back to those flimsy, flat cookies again! They have that serious, substantial bite we all crave. Seriously, these are the cookies you want when you need a real treat.
- They actually bake up extra thick, just like the ones from the famous bakeries—no spreading allowed!
- We use a massive amount of chocolate, so every single bite is gooey, rich, and overflowing.
- That satisfying, rustic crunch from the chopped walnuts cuts through the sweetness perfectly.
- The dough is easy to handle, even though it looks fancy! It comes together faster than you think.
- They taste incredible straight from the cooling rack, although they are even better the next day.
- You get that amazing homemade warmth without needing a dozen weird specialized ingredients.
Essential Ingredients for Thick Levain Style Chocolate Chip Walnut Cookies
Okay, let’s talk about what goes into these beasts. Getting the right ingredients is half the battle, especially if you want that true, chewy, thick texture, and not a puddle on the baking sheet. I’ve detailed everything down to the exact way the butter should be cut because, honestly, these tiny details really do matter when you’re chasing a bakery copycat recipe.
Remember how I mentioned tracking down the perfect ingredients? I found some great tips on using different foundational items over at this recipe, but for these chunky walnut cookies, precision is key!
We are focusing on one main group here: the cookie dough itself. Pay extra close attention to the flour type, as that plays a huge role in volume!
- The Butter Must Be COLD Unsalted Butter, cut into small cubes. Seriously, it needs to be cold so it creams up without melting too fast.
- Light Brown Sugar (3/4 cup) and Granulated White Sugar (1/2 cup). The brown sugar gives us that hint of molasses flavor we need.
- Large Eggs (2). Room temperature is fine here, they just need to blend in properly.
- Vanilla Extract (2 tsp) – if you skip this, I might cry a little! It truly enhances the chocolate flavor.
- Cornstarch (1 tsp) is our secret weapon for tenderness; don’t skip it!
- Baking Soda (1 tsp) and Salt (1/2 tsp) for balance.
- The Flours: You need both Cake Flour (1 cup) and All-Purpose Flour (1.75 cups). Cake flour keeps them lighter despite their size.
- The Stars of the Show: About 2 cups of Semi-Sweet Chocolate Chips—I swear by Guittard or Ghirardelli. And you need 2 cups of Chopped Walnuts; they need to be big pieces!
Expert Tips for Making Thick Levain Style Chocolate Chip Walnut Cookies
Now listen up, because how you handle this dough determines if you get a chunky cookie or a flat coaster. We’re chasing that famous thick profile, and it takes a little finesse! Don’t worry if it feels a bit weird; these tips are what make these copycat cookie recipes so authentic. This is where the magic happens, folks.
Achieving the Signature Extra Thick Cookies Texture
Remember I said the butter has to be cold when you start creaming? That’s vital! Cold fat melts slower in the oven, which means your cookie spreads less and stays tall. Also, once you add the flour mixture, treat it gently. Overmixing develops gluten—and gluten wants your cookie to be flat and crispy, which is the opposite of what we want here!
And when you scoop the dough? Form it really roughly! Don’t fuss over making a perfect sphere. Those craggy peaks and valleys on the dough ball help trap air and keep that wonderfully thick structure as they bake. A quick 15-minute chill also helps lock everything in place before hitting that high heat.
Chocolate Quality Matters for Your Thick Levain Style Chocolate Chip Walnut Cookies
Since you’re getting these huge, decadent cookies, you absolutely must use good chocolate! I feel like I sound like my high school home economics teacher saying this, but it’s true. Cheap chocolate chips just don’t melt right; they often stay hard and waxy. We need that luscious, gooey melt that defines these Thick Levain Style Chocolate Chip Walnut Cookies.
If you can swing it, grab chips from Ghirardelli or Guittard—I promise you will taste the difference immediately when you break one of these giants in half. It’s worth the extra dollar or two, trust me, for cookies this substantial!
Step-by-Step Instructions for Chunky Walnut Cookies
Now for the fun part—we get to mix stuff! Getting the right texture for these chunky walnut cookies starts right here in the mixer. Remember, we preheat the oven to 410 degrees F first, and we line those baking sheets with parchment or silicone mats. Gotta protect that counter space, right?
You’ll want to look at the full list of ingredients before you start, but let’s get mixing!
Preparing the Dough Base
This is where the texture really starts to happen. Get your cold, cubed butter into your standing mixer first. Hit it with both sugars, but don’t just blast it on high! Start it low for about 30 seconds just to combine, then bump it to medium for another 30 seconds, and only then do you crank it high for 30 seconds more until it looks light and fluffy. That controlled creaming is everything!
Next, we add the eggs one by one, scraping down the sides when you need to, followed by that splash of vanilla. Then, it’s time for the dry stuff—cornstarch, baking soda, salt, and both flours. Mix this on low speed until it’s *just* incorporated. I mean it, don’t go past that point! Fold in the chocolate chips and walnuts by hand or on the absolute lowest setting, just until you see them distributed. Wrap it up and chill for 15 minutes.

Portioning and Baking Your Thick Levain Style Chocolate Chip Walnut Cookies
This is the secret to their size! Grab your digital scale. We need a good 6 ounces of dough per cookie. That sounds like a lot, I know, but that’s how you get that perfect bakery height! Shape it roughly into a ball—and I mean ROUGHLY. Smoother dough spreads more, so leave those glorious, uneven edges.
Place only four dough balls on each baking sheet, giving them a good 3 inches of space to breathe. They bake hot and fast at 410°F, usually between 10 to 13 minutes. You are aiming for cookies that look dull on the edge but still look a little soft or underdone in the very center. Do NOT over-bake them, or they will turn into rockers!
Cooling and Setting Up Your Thick Levain Style Chocolate Chip Walnut Cookies
Okay, deep breath, because this next step is crucial if you want those giant cookies to actually hold their shape when you move them—don’t even think about touching them too soon! Because these Thick Levain Style Chocolate Chip Walnut Cookies come out looking slightly soft in the middle (which is exactly what we want for gooeyness!), they need time to finish baking on the hot sheet.
Wait a full 30 minutes, just let them sit right there on the parchment paper. They might look soft now, but trust me; moving them while they’re hot means they’ll collapse into sweet soup. Patience pays off here, giving them that sturdy base needed to support all that chocolate and walnut goodness!
Serving Suggestions for Copycat Cookie Recipes
Alright, we have conquered the recipe, and now you have these absolute monsters of cookies sitting on your cooling racks. What do you do with these magnificent creations? Well, these aren’t your dainty little tea cookies; they demand attention!
My favorite way to enjoy a fresh, still-slightly-warm copycat cookie recipe like this is embarrassingly simple: with a huge glass of ice-cold milk. Nothing beats that contrast between the cold dairy and the melted, gooey chocolate. Seriously, don’t skip the milk!
If you’re having guests or just want something a little more elevated, try cutting one of these chunky walnut cookies in half and serving it warm with a scoop of good vanilla bean ice cream on top. It becomes an instant, stunning dessert that looks way harder to make than it actually was. That warm chocolate oozing out is just heaven.
For the grown-ups, they pair beautifully with a strong cup of coffee or maybe even a homemade latte. If you’re in the mood for something cozy that matches all those spices we love in cookies, you absolutely have to try my recipe for a homemade chai tea latte. The spice profile just sings alongside the walnuts and chocolate in these extra thick cookies!
Basically, treat these babies like the main event they are. They are too thick and too delicious to just be a side snack!
Storage and Reheating Instructions for Extra Thick Cookies
These extra thick cookies are so big and chunky that they stay fresh longer than those flimsy, thin ones, which is great news for us slackers who don’t want to bake a fresh batch every single day! The real trick is keeping the moisture locked in so they don’t get oddly chewy or hard around the edges.
When they are completely cool—and I mean 100% room temperature, otherwise you’re steaming them in a jar—you need an airtight container. I use those big glass jars with clamp lids. Layer them up, maybe with a little square of parchment paper between any cookies that are touching, just to be safe. They hold up beautifully on the counter for about three days like this.
If you’re planning way ahead, you can absolutely freeze the dough balls (see the FAQ for that!). But if the cookies are already baked, they’ll last up to a week in the freezer if wrapped tightly in plastic wrap first. Just take them out about an hour before you want one.
Now, for the best part: reheating! If you’re craving that fresh-from-the-oven gooeyness, don’t use the microwave for too long, or they get tough fast. Pop one right into a toaster oven or a regular oven set to about 300 degrees F for just 3 to 5 minutes. You want them warm enough for the chocolate to get melty again, but not long enough to fully bake through again. The warmth wakes up all those amazing fats, and boom—you have a perfect, warm Thick Levain Style Chocolate Chip Walnut Cookie!
Frequently Asked Questions About Thick Levain Style Chocolate Chip Walnut Cookies
I know you might have a few lingering questions now that you’ve seen just how serious these cookies are. It’s normal! When you are trying to nail a huge bakery cookie like this, the details matter so much. If you are anything like me, you have to get it exactly right before you can fully commit to an entire batch!

Can I make these levain style cookies without walnuts?
Oh, absolutely you can! While the walnuts give these levain style cookies that incredible textural contrast, they are not mandatory. If you are nut-free or just not a fan, you can simply leave them out. However, I have to warn you: you’ll need to replace that volume with more chocolate chips to keep the cookie thick and not overly reliant on just the dough.
If you want to stay in the nut family but can’t do walnuts, pecans are a wonderful substitute. They have a slightly sweeter flavor that pairs surprisingly well with this amount of chocolate. Just substitute the two cups of walnuts with two cups of your preferred nut or extra chocolate!
How do I ensure my cookies stay extra thick and do not spread too much?
This is the biggest concern, right? You’re fighting gravity and heat simultaneously! The key to keeping these Thick Levain Style Chocolate Chip Walnut Cookies tall is twofold, just like we talked about in the tips section. First, make sure your butter is genuinely cold when you start creaming it—it should be firm cubes, not soft squares!
Second, and this is crucial: do not smooth the dough balls out! When you portion them (yep, use that scale—about 6 oz!), just roll them gently so they hold together, but leave them shaggy and uneven. Those rough edges and cold centers take longer to melt, baking up tall instead of out. That 410°F heat helps set the outside quickly too!
What is the best way to freeze the dough for these chunky walnut cookies?
I almost always freeze half the dough because making chunky walnut cookies is a commitment, and you want to be able to enjoy them weeks later! It’s super easy. Once you’ve mixed your dough and it’s chilled for that initial 15 minutes, scoop out your 6-ounce portions and shape them roughly.
Place the raw dough balls on a baking sheet lined with parchment, ensuring they aren’t touching at all. Pop that sheet straight into the freezer until the balls are rock hard—usually about two hours. Once they are solid, you can transfer them to an airtight freezer bag or container. When you’re ready to bake, just take the dough right from the freezer, give it an extra minute or two on the baking sheet to relax, and bake it at the same 410°F. You might need to add 1 or 2 minutes to the baking time!

Thick Levain Style Chocolate Chip Walnut Cookies
Ingredients
Equipment
Method
- Preheat your oven to 410 degrees F. Line 2 baking sheets with parchment paper or silicone liners and set them aside.
- In the bowl of a stand mixer, cream together the butter and both sugars using the paddle attachment on low speed for 30 seconds. Increase the speed to medium and beat for another 30 seconds, then increase to high speed for a final 30 seconds. The mixture should look light and fluffy.
- Beat in the eggs, one at a time, scraping down the sides of the bowl with a spatula as needed. Add the vanilla, if using.
- Add the cornstarch, baking soda, salt, cake flour, and all-purpose flour. Mix on low speed until just incorporated. Add the chocolate chips and chopped walnuts and mix until just combined. Refrigerate the dough for 15 minutes.
- Using a digital kitchen scale, measure out a rough 6 ounce ball of dough. Shape it roughly and place it on the baking sheet. You do not want the dough ball to be smooth; just barely form it into a rough ball shape. Place 3 more dough balls on one baking sheet, spacing them about 3 inches apart. You should have 4 dough balls on one sheet.
- Bake for 10 to 13 minutes, working with one sheet at a time on the middle rack of the oven. The cookies should look cooked and have a duller finish on the outside while still looking soft and underdone on the inside. Start checking at the 10-minute mark because it is important not to over-bake these. Remember, the cookies will continue to finish cooking on the baking sheet after you remove them from the oven.
- Allow the cookies to cool completely on the baking sheet, about 30 minutes, before moving them to a wire rack or storing them. The cookies are very delicate right after baking, so do not move them too soon.

Getting diagnosed with non-celiac gluten sensitivity in my late twenties felt like losing my Italian identity. Growing up in nonna’s Brooklyn kitchen, learning traditional techniques that suddenly became off-limits—I decided to fight for those family food traditions instead of giving up.
With my food journalism background and European baking training, I became obsessed with recreating authentic flavors in gluten-free formats. I’ve adapted 400+ traditional recipes from various cultures, with my gnocchi recipe winning “Recipe of the Year” from the National Gluten-Free Living Awards in 2022.
I collaborate with the Italian-American Cultural Center to document traditional family recipes and volunteer with the Westchester Celiac Support Group, teaching monthly pasta-making classes.
