Chocolate Walnut Cookies That Are Soft, Chunky, and Bakery-Style

If you’ve ever waited in line outside the famous Levain Bakery in New York City, you know the hype is real. Their signature chocolate walnut cookies are unlike any other — huge, thick, gooey-centered, with a crisp exterior and generously studded with chocolate and walnuts.

This homemade version brings all that bakery-style decadence into your own kitchen. These cookies are big, bold, and utterly satisfying — each bite delivering deep chocolate flavor, crunchy walnuts, and that iconic almost-undercooked center.

Perfect for holidays, gifting, or just treating yourself, this copycat Levain Chocolate Walnut Cookie recipe nails the texture and flavor that made the original a legend.

Ingredients Overview

Let’s break down what makes these cookies stand out and how each ingredient contributes to that signature result.

All-Purpose Flour

Levain cookies are famously thick and substantial. A high flour-to-butter ratio helps achieve that structure. Some bakers also add cake flour for tenderness, but regular all-purpose works just fine.

Cornstarch (Optional)

Helps soften the interior and keep the cookies tender without spreading too much.

Baking Soda and Baking Powder

Using both ensures a balanced rise: the baking soda gives spread, while baking powder offers lift.

Cold Unsalted Butter

Unlike many cookie recipes that use softened butter, Levain-style cookies use cold butter, which helps minimize spreading and keeps the cookies tall and dense.

Brown Sugar and Granulated Sugar

Brown sugar adds moisture and depth of flavor, while white sugar contributes to crisp edges. A higher brown-to-white sugar ratio gives that chewy center.

Eggs

Two large eggs, cold from the fridge, help bind the dough and contribute to the cookies’ thickness.

Semi-Sweet Chocolate Chips or Chunks

Use good-quality chocolate (like Guittard or Ghirardelli) for best flavor. Chunks melt into pockets of gooey chocolate, while chips maintain structure.

Walnuts

The nuts aren’t just a garnish — they make up a big part of the texture and balance the sweetness with their earthy crunch. Use raw or lightly toasted walnuts, coarsely chopped.

Salt and Vanilla Extract

Essential for balancing sweetness and boosting flavor. A pinch of flaky salt on top adds a gourmet finish.

Substitution Ideas

• Gluten-Free: Use a 1:1 gluten-free baking flour with xanthan gum.

• Nut-Free: Omit walnuts or substitute with sunflower seeds or extra chocolate chunks.

• Chocolate Variations: Try dark chocolate chunks, milk chocolate, or even peanut butter chips for a twist.

• Vegan Option: Use plant-based butter and flax eggs (though the texture will vary).

Step-by-Step Instructions

Follow these steps carefully to achieve bakery-style cookies with a gooey center and crisp edges.

1. Prep the Ingredients

Cut 1 cup (2 sticks) of cold unsalted butter into small cubes. Keep refrigerated until ready to cream.

Roughly chop 2 cups of walnuts. Measure out chocolate chunks or chips (2 cups total).

Line a baking sheet with parchment paper. Preheat oven to 400°F (204°C).

2. Mix the Dry Ingredients

In a bowl, whisk together:

• 3¼ cups all-purpose flour

• 1 tablespoon cornstarch (optional)

• 1 teaspoon baking soda

• 1 teaspoon baking powder

• ½ teaspoon salt

Set aside.

3. Cream the Butter and Sugars

In a stand mixer with the paddle attachment (or using a hand mixer), cream:

• Cold butter cubes

• ¾ cup light brown sugar

• ½ cup granulated sugar

Mix on medium-low speed until combined but not fully smooth. About 1–2 minutes — it won’t look creamy like traditional doughs.

4. Add Eggs and Vanilla

Add:

• 2 cold large eggs

• 1½ teaspoons vanilla extract

Mix just until incorporated. Scrape down the bowl once or twice.

5. Combine Dry and Wet

Slowly add the dry ingredients and mix on low speed until a thick dough forms. It will be slightly crumbly but should hold together when pressed.

6. Fold in Chocolate and Walnuts

Add:

• 2 cups semi-sweet chocolate chunks

• 2 cups coarsely chopped walnuts

Fold by hand or with a spatula until evenly distributed.

7. Portion the Dough

Divide the dough into 6–8 large balls — each should weigh about 6 ounces (170 grams), roughly the size of a baseball.

Do not flatten the dough — bake them as tall mounds to get the gooey centers.

8. Bake

Place 3–4 dough balls on a parchment-lined sheet pan with space between each. Bake at 400°F for 9–11 minutes.

The tops should look golden and slightly cracked, but the centers will still be soft.

Remove and let cool on the baking sheet for at least 15 minutes before transferring — they will continue setting as they cool.

Tips, Variations & Substitutions

• Cold Ingredients: Stick to cold butter and eggs — this keeps the cookies tall and dense.

• Don’t Overmix: Especially after adding the eggs. Overmixing can cause the cookies to be tough.

• Weigh the Dough: For even baking, use a kitchen scale. Levain cookies are large — around 6 oz each.

• Double Chocolate: Swap ¼ cup of flour for unsweetened cocoa powder for an ultra-chocolatey version.

• Freezer-Friendly: Freeze portioned dough balls and bake straight from frozen, adding 1–2 extra minutes.

Serving Ideas & Occasions

Levain-style cookies make a big impact — literally and figuratively. They’re a favorite for:

• Bake sales and holiday cookie boxes

• Birthday party treats

• Weekend indulgences with coffee or hot chocolate

• Gifting (wrap individually in parchment and ribbon)

Serve slightly warm for that gooey chocolate center. Pair with a tall glass of cold milk, a cappuccino, or a scoop of vanilla ice cream.

Nutritional & Health Notes

These cookies are rich and satisfying — you may only need half! Each cookie delivers a hearty dose of energy from:

• Healthy fats from walnuts

• Protein from eggs and nuts

• Carbohydrates from flour and sugar

• Satisfying fiber if you use whole wheat or nut flour variations

They’re an occasional treat rather than an everyday snack, but their portion size makes them great for sharing or saving half for later.

FAQs

Q1: Why are Levain cookies baked at a high temperature?
A: The 400°F oven helps set the exterior quickly while keeping the inside soft and underbaked — a signature trait of Levain-style cookies.

Q2: Can I make them smaller?
A: Yes, but reduce baking time to 8–9 minutes for 3 oz cookies. Keep the dough mound tall to retain that gooey center.

Q3: Why is the butter cold?
A: Cold butter prevents the cookies from spreading too much and helps achieve the thick, dense texture.

Q4: Can I use a different nut besides walnuts?
A: Yes — pecans, almonds, or hazelnuts work well, though walnuts offer the most classic flavor and texture balance.

Q5: How should I store these cookies?
A: Store in an airtight container at room temperature for up to 4 days. Reheat in the microwave for 10–15 seconds to refresh the gooey texture.

Q6: Can I freeze the dough?
A: Absolutely. Freeze shaped dough balls for up to 3 months. Bake from frozen with just a minute or two extra.

Q7: Do I need a mixer?
A: A stand mixer makes things easier, but you can mix by hand with a sturdy spoon — just expect a bit of a workout when creaming the cold butter.
