Levain Chocolate Walnut Cookie – Thick, Gooey Bakery-Style Cookie

The Levain Chocolate Walnut Cookie is inspired by the iconic cookies made famous by Levain Bakery in New York City. These massive, ultra-thick cookies have a crisp golden exterior, a soft, gooey center, and are generously packed with chocolate chunks and walnuts. Unlike typical thin cookies, these bake up tall and chewy — almost like a cookie-meets-brownie hybrid.

Their fame comes not only from their size but from the perfect balance of rich chocolate, toasted walnuts, and a buttery dough that’s soft inside and slightly crisp on the edges. It’s the ultimate bakery-style treat you can make at home, perfect for cookie lovers who crave bold flavor and indulgent texture.

Whether you’re baking for the holidays, gifting to friends, or just satisfying a serious cookie craving, this Levain-style recipe delivers bakery-quality results without a trip to NYC.

Ingredients Overview

Each ingredient in this recipe contributes to the signature texture and rich flavor. Here’s what you’ll need:

Unsalted Butter

Cold, cubed butter is key — it helps prevent the cookies from spreading too much, resulting in that signature thick, tall shape. Unlike most cookie recipes, you don’t want room-temperature butter here.

Brown Sugar and Granulated Sugar

A higher ratio of brown sugar adds moisture, chewiness, and a slight molasses flavor. Granulated sugar adds structure and helps create those lightly crisp edges.

Eggs

Use large eggs, straight from the fridge. Cold eggs help keep the dough firm and contribute to the cookie’s dense interior.

All-Purpose Flour

This gives the cookies their structure. Measure carefully (spooned and leveled) to avoid overly dense cookies.

Cornstarch

A small amount of cornstarch creates a softer texture and helps keep the centers tender.

Baking Powder and Baking Soda

This combination gives just enough rise to create that thick, lofty height without making the cookies cakey.

Salt

Enhances all the other flavors, especially balancing the sweetness and bringing out the nuttiness of the walnuts.

Semisweet or Dark Chocolate Chunks

Use chopped chocolate bars or high-quality chunks instead of chips for uneven pockets of melted chocolate. This mimics the Levain texture and flavor.

Walnuts

Toasted walnuts add crunch and a buttery richness that pairs beautifully with dark chocolate. Chop them coarsely for the best texture.

Step-by-Step Instructions

1. Prepare the Butter and Sugars

Cube the cold butter and beat it with both sugars in a stand mixer or using a hand mixer. This may take a bit longer than creaming softened butter — expect 2–3 minutes on medium-high speed until light and crumbly.

2. Add Eggs

Add cold eggs one at a time, mixing until fully combined. The mixture should look cohesive and slightly thickened.

3. Combine Dry Ingredients

In a separate bowl, whisk together flour, cornstarch, baking powder, baking soda, and salt. Add this mixture gradually to the wet ingredients, mixing on low until just combined.

Avoid overmixing — this dough is thick but should come together cleanly.

4. Fold in Chocolate and Walnuts

Using a wooden spoon or spatula, fold in large chunks of chocolate and toasted walnuts. Be generous — the dough should be studded throughout.

5. Portion and Chill the Dough

Scoop the dough into large balls — around 6 oz each (think baseball-sized). Form loosely into mounds rather than perfectly smooth balls. This gives you the craggy, rustic Levain look.

Chill the portioned dough balls in the refrigerator for at least 1 hour or up to overnight.

6. Bake

Preheat your oven to 400°F (205°C). Line a baking sheet with parchment paper. Place chilled dough balls 3 inches apart (they spread a little, but stay tall).

Bake for 10–12 minutes. The tops should look just set, and the edges lightly browned — the centers will still look soft. Let them cool on the baking sheet for 10 minutes before transferring.

7. Serve Warm

Levain cookies are best served warm when the chocolate is melty and the center is gooey. If eating later, microwave for 10–15 seconds for that fresh-baked effect.

Tips, Variations & Substitutions

Expert Tips

• Use cold ingredients — this is critical for structure.

• Don’t overbake. Cookies should look slightly underdone in the center.

• Use a kitchen scale to ensure consistent size and bake time.

Flavor Variations

• Double Chocolate Walnut: Replace ½ cup flour with cocoa powder.

• Peanut Butter Swirl: Add dollops of peanut butter before forming dough balls.

• Triple Chocolate: Mix dark, milk, and white chocolate for extra richness.

Substitutions

• Gluten-Free: Use a 1:1 gluten-free baking flour blend. The cookies will be slightly more delicate.

• Nut-Free: Omit walnuts or swap with toasted pumpkin seeds or sunflower seeds.

• Vegan: Use plant-based butter and egg replacers (like flax eggs) along with dairy-free chocolate.

Serving Ideas & Occasions

These cookies are impressive and indulgent — perfect for:

• Holiday Gifting: Wrap individually in parchment and ribbon.

• Special Desserts: Serve with a scoop of vanilla ice cream or sandwich ice cream between two cookies.

• Bake Sales & Parties: Their massive size and decadent texture make them irresistible for sharing.

• After-Dinner Treat: One cookie is enough for two (or not — we won’t judge).

The rich aroma of toasted nuts and dark chocolate makes these ideal for cozy winter nights or festive dessert spreads.

Nutritional & Health Notes

Levain-style cookies are a treat — and they’re meant to be!

• Portion Tip: One cookie can weigh over 6 ounces, so consider sharing or making smaller versions for less indulgence per serving.

• Walnuts: Add healthy fats and protein, making the cookie more satiating.

• Dark Chocolate: Offers antioxidants and richer flavor with less sugar than milk chocolate.

If you’re looking for a lighter version, you can make mini 3-ounce cookies and reduce sugar by 10–15%.

FAQs

Q1: Why is the butter cold in this recipe?
A1: Cold butter prevents the cookies from spreading too much during baking, helping them stay thick and tall — just like the original Levain Bakery cookies.

Q2: Can I freeze the dough?
A2: Yes, scoop and freeze the dough balls on a tray, then transfer to a zip-top bag. Bake straight from frozen, adding 1–2 minutes to the bake time.

Q3: What’s the best chocolate to use?
A3: Use chopped bars of semisweet or dark chocolate (60–70%). Chips work too, but chopped chocolate melts more and gives gooey pockets inside.

Q4: Do I need a mixer for this recipe?
A4: A stand mixer is helpful due to the thick dough, but a hand mixer with some muscle power will work. Mixing by hand is difficult but possible.

Q5: Can I reduce the sugar?
A5: Yes — reducing each sugar by ¼ cup still yields a rich cookie with less sweetness. Don’t reduce too much, or you may lose structure.

Q6: Why did my cookies turn out cakey?
A6: Too much flour or overmixing can lead to cakey cookies. Be sure to spoon and level your flour and mix just until combined.

Q7: How do I get the signature chunky look?
A7: Don’t roll the dough into smooth balls. Instead, form rough mounds with your hands. The uneven shape creates those signature bakery-style peaks and cracks.
