1. Introduction: The Legend of the Six-Ounce Cookie
There is a specific kind of magic that happens on West 74th Street in New York City. If you follow the scent of toasted walnuts and caramelized sugar, you’ll find yourself standing in line at Levain Bakery. What started as a small bread shop in 1995 birthed a global phenomenon: a cookie so massive, so mountain-like, and so unapologetically gooey that it redefined the American dessert landscape.
The Levain-style cookie isn’t just a snack; it’s an architectural marvel. Unlike the flat, chewy discs found in most bakeries, these cookies are hefty, weighing in at nearly half a pound each. They defy the traditional laws of baking by remaining “underbaked” in the center while sporting a rugged, golden-brown crust.
For many home bakers, recreating this at home is the ultimate “Mount Everest” of recipes. The secret lies not just in the ingredients, but in the thermal mass of the dough and the specific cold-start baking technique. Whether you’re a lifelong New Yorker or someone who has only seen these beauties on Instagram, this recipe brings that iconic, molten-centered experience straight to your kitchen.
2. Recipe Overview
- Cuisine Type: American / New York Bakery Style
- Difficulty Level: Intermediate (Requires precision in temperature and timing)
- Prep Time: 20 minutes
- Chilling Time: 2 hours (minimum) to 24 hours (recommended)
- Cook Time: 10–13 minutes
- Total Time: Approx. 2 hours 40 minutes
- Dietary Classifications: Vegetarian. Contains gluten, dairy, and nuts (optional).
3. Equipment and Tools
To achieve the “mountain” shape, you cannot rely on standard cookie-cutter methods. You need tools that handle high heat and heavy dough.
- Digital Kitchen Scale: Essential for weighing 6oz (170g) portions.
- Stand Mixer or Electric Hand Mixer: The dough is very heavy; a paddle attachment is preferred.
- Large Baking Sheets: Heavy-duty aluminum rimmed baking sheets (13″ x 18″).
- Parchment Paper or Silpat Mats: To prevent the bottoms from over-browning.
- Wire Cooling Rack: For proper airflow after baking.
- Large Mixing Bowls: For whisking dry ingredients.
- Measuring Spoons/Cups: If a scale is unavailable (though weight is highly recommended).
4. Serving Suggestions
These cookies are a meal in themselves, but here is how to elevate the experience:
- The Classic Pairing: Serve warm with a tall glass of ice-cold whole milk. The fat in the milk cuts through the richness of the dark chocolate.
- The “À La Mode”: Break a warm cookie in half and top with a scoop of high-quality Madagascar vanilla bean ice cream.
- Beverage Pairings: A dark roast coffee or an espresso balances the sweetness. For an adult treat, try a glass of Tawny Port or a stout beer.
- Garnish: A light dusting of Maldon sea salt flakes immediately after baking enhances the chocolate notes.

Health Note: These are an indulgent treat. For a lighter version, you can scale the dough balls down to 3oz, though the “gooey” texture profile will change.
6. Storage and Reheating
Because these cookies are baked at a high temperature for a short time, they contain a lot of moisture.
- Room Temperature: Store in an airtight container for up to 3 days.
- Freezing (Raw): Form the balls and freeze. Add 2 minutes to the bake time when baking from frozen.
- Freezing (Baked): Wrap individually in plastic wrap and freeze for up to 2 months.
- Reheating (The Secret): Never microwave for more than 10 seconds. For the best “just-baked” texture, place in a 350°F (175°C) oven for 5 minutes.
7. Expert Tips and Variations
Professional Chef Tips
- Cold Butter is Key: Unlike most recipes calling for “room temperature” butter, use butter that is slightly cool to the touch. This prevents the cookies from spreading too thin.
- Don’t Overmix: Once the flour enters the bowl, mix only until no streaks remain. Overworking the dough creates too much gluten, leading to a “bready” cookie rather than a “gooey” one.
- High Heat: Baking at 415°F (212°C) shocks the outside of the dough, setting the crust while the inside remains molten.
Creative Variations
- The “Dark” Variant: Substitute 1/2 cup of flour for high-quality Dutch-processed cocoa powder.
- The Nut-Free Swap: Replace walnuts with toasted sunflower seeds or simply double the chocolate chips.
- White Chocolate Macadamia: Swap dark chips for white chocolate and walnuts for macadamias.

9. Step-by-Step Instructions
Step 1: Creaming the Base
In your stand mixer, combine the cold, cubed butter with the brown and white sugars. Beat on medium-high for about 4 minutes. You are looking for a pale, fluffy texture, but ensure the butter isn’t melting.
Step 2: The Liquid Phase
Add the eggs one at a time, beating well after each addition. Scrape down the sides of the bowl to ensure no butter pockets remain.
Step 3: Integrating Dry Ingredients
In a separate bowl, whisk together the cake flour, all-purpose flour, cornstarch, baking soda, and salt. Turn the mixer to the lowest setting and slowly add the dry mix to the wet. Stop as soon as the flour disappears.
Step 4: The Mix-ins
Fold in the chocolate chips and chopped walnuts by hand or on the lowest mixer setting for 5 seconds.
Step 5: Scaling and Shaping
Using a scale, measure out 6-ounce (170g) portions. Do not roll them into smooth balls. Keep them “nubbly” and loose, looking like small mountains. This texture creates the signature craggy crust.
Step 6: The Chill (Crucial)
Place the dough mounds on a tray and refrigerate for at least 2 hours. This hydrates the flour and prevents the fats from leaking out too quickly in the hot oven.
Step 7: The High-Heat Bake
Preheat your oven to 415°F (212°C). Place 4 cookies per sheet (they need space!). Bake for 10–13 minutes. The tops should be golden brown, but the cookies should look slightly “wet” in the cracks.
Step 8: The Rest
This is the hardest part. Let the cookies rest on the hot baking sheet for at least 15 minutes. They are still cooking internally. If you move them too soon, they will fall apart.
10. Frequently Asked Questions (FAQ)
Q: Why use cake flour and all-purpose flour?
A: Cake flour has a lower protein content, which creates a delicate, melt-in-your-mouth texture. All-purpose flour provides the strength needed to hold up a 6oz cookie.
Q: My cookies came out flat. What happened?
A: Most likely, your butter was too warm, or your oven temperature was too low. Ensure the butter is cold and use an oven thermometer to verify the heat.
Q: Do I have to use walnuts?
A: While walnuts provide the classic Levain flavor and structural support (preventing the cookie from collapsing), you can omit them. If you do, the cookie may spread slightly more.
Q: Can I make smaller cookies?
A: Yes, but you must reduce the temperature to 375°F (190°C) and bake for 8–10 minutes to avoid drying them out.
Q: Why cornstarch?
A: Cornstarch acts as a softener, giving the cookie that “gooey” fudge-like center even after it has cooled
