Copycat Levain Bakery Chocolate Chip Walnut Cookie Recipe – Big, Gooey, and Irresistible

If you’ve ever stood in line for a warm Levain cookie, you know why people rave about them. Massive, gooey in the middle, crisp on the edges, and packed with chocolate and walnuts—there’s nothing quite like it. The good news: you can make a convincing version at home without fancy equipment.

This recipe nails the thick texture, the molten center, and that signature chunky bite. You’ll get bakery-level results with straightforward steps and a few key tricks.

What Makes This Recipe So Good

• Thick, bakery-style texture: A higher flour ratio and cold dough help the cookies stay tall and soft inside.
• Molten center, crisp edges: The short bake time keeps the middle gooey while the outside sets.
• Bold mix-ins: Big chocolate chunks and toasted walnuts add contrast and bite in every piece.
• Simple method: No special tools required—just a mixer, a sheet pan, and a little patience.
• Make-ahead friendly: Dough freezes well, so you can bake off a few cookies whenever you want.

What You’ll Need

• Cold unsalted butter: 1 cup (226 g), cut into cubes
• Light brown sugar: 1 cup (200 g), packed
• Granulated sugar: 1/2 cup (100 g)
• Large eggs: 2, cold
• Vanilla extract: 2 teaspoons
• All-purpose flour: 3 cups (360 g)
• Cake flour (optional but recommended): 1 cup (120 g) — or use all-purpose if needed
• Cornstarch: 2 teaspoons
• Baking powder: 1 teaspoon
• Baking soda: 1/2 teaspoon
• Kosher salt: 3/4 teaspoon (use 1/2 teaspoon if using table salt)
• Semi-sweet chocolate chips or chunks: 2 cups (about 340 g)
• Walnuts, roughly chopped and lightly toasted: 2 cups (about 220 g)

Note: Using part cake flour and a touch of cornstarch mimics a tender, thick crumb. Cold butter and cold eggs help keep the dough sturdy.

How to Make It

1. Toast the walnuts: Spread walnuts on a baking sheet and toast at 350°F (175°C) for 6–8 minutes until fragrant. Cool completely. This adds flavor and keeps them from going soggy in the dough.
2. Prep the dry mix: In a bowl, whisk together all-purpose flour, cake flour, cornstarch, baking powder, baking soda, and salt. Set aside.
3. Cream the butter and sugars: In a stand mixer with a paddle (or using a hand mixer), beat cold cubed butter with brown and granulated sugar on medium speed for 2–3 minutes.You want it combined and a bit fluffy, but not overly airy.
4. Add eggs and vanilla: Mix in eggs one at a time, then add vanilla. Scrape the bowl as needed. The dough will look thick and slightly uneven—totally fine.
5. Combine wet and dry: Add the dry ingredients in two additions on low speed, mixing just until no streaks of flour remain. Don’t overmix.
6. Fold in chocolate and walnuts: Stir in the chocolate and cooled walnuts by hand. The dough should be dense and chunky.
7. Portion generously: Scoop large 6-ounce mounds (about the size of a large ice cream scoop, roughly a heaping 1/2 cup). You should get 8 big cookies. Keep them tall rather than wide.
8. Chill the dough: Place the dough mounds on a tray, cover, and chill for at least 90 minutes, preferably 2 hours. Cold dough means thick cookies.
9. Preheat and prep pans: Heat the oven to 400°F (205°C). Line two baking sheets with parchment paper. Space cookies well—four per sheet.
10. Bake: Bake one sheet at a time for 10–12 minutes, until the tops are lightly golden but the centers still look soft and slightly underbaked. Rotate the pan at the 8-minute mark if your oven has hot spots.
11. Rest on pan: Let cookies sit on the hot sheet for 10–12 minutes. They’ll finish setting while staying gooey inside.
12. Serve warm: Enjoy as is, or with a sprinkle of flaky salt on top for contrast.

Keeping It Fresh

• Room temperature: Store cooled cookies in an airtight container for up to 3 days.Slip in a slice of bread to keep them soft.
• Freeze baked cookies: Wrap individually and freeze up to 2 months. Reheat at 300°F (150°C) for 6–8 minutes.
• Freeze dough: Freeze shaped dough mounds on a tray, then transfer to a freezer bag for up to 3 months. Bake from frozen at 400°F (205°C) for 12–14 minutes.

Why This is Good for You

• Walnuts bring benefits: They’re rich in omega-3s, fiber, and antioxidants, adding nutrients and a satisfying crunch.
• Built-in portion control: Big cookies mean one is usually enough, helping you enjoy a treat mindfully.
• Homemade wins: You control the ingredients—quality chocolate, real butter, and less processed add-ins.

This isn’t a diet cookie, but it’s a more wholesome, satisfying treat than most store-bought options.

Enjoy it fully and balance it with the rest of your day.

Pitfalls to Watch Out For

• Skipping the chill: Warm dough spreads too much, losing that signature height.
• Overbaking: If you wait until the centers look fully done, you’ll miss the gooey middle. Pull when the edges set and tops just start to color.
• Hot nuts or chocolate: Stirring in warm walnuts or melty chocolate can make the dough greasy. Let mix-ins cool first.
• Wrong flour measurements: Too little flour and the cookies flatten; too much and they turn dry. Weigh your flour if possible.
• Overmixing: Mix only until combined to avoid tough cookies.

Alternatives

• No cake flour: Use all-purpose flour only (total 4 cups or 480 g) and keep the cornstarch. Texture will still be thick and tender.
• Nut-free version: Replace walnuts with more chocolate, or use pumpkin seeds or pretzel chunks for crunch.
• Different chocolates: Try a mix of semi-sweet and dark chunks. Milk chocolate will be sweeter and softer.
• Smaller cookies: Make 3-ounce portions and bake 8–10 minutes.Watch closely to avoid overbaking.
• Gluten-free: Use a good 1:1 gluten-free baking flour with xanthan gum and keep the cornstarch. Expect slightly more spread.
• Dairy-free: Use a quality vegan butter block and dairy-free chocolate. Chill time becomes even more important.

FAQ

How do I keep the cookies thick and tall?

Use cold ingredients, chill the dough, and shape tall mounds.

A hot oven (400°F/205°C) sets the outside quickly so the cookies hold their height.

Why use both baking powder and baking soda?

The combo gives lift and spread control. Baking powder provides structure and height, while baking soda helps browning and a slight spread for those crisp edges.

Do I have to use walnuts?

No. Walnuts add classic texture and flavor, but you can swap with pecans, almonds, or skip nuts entirely and add more chocolate or a crunchy mix-in.

Can I make the dough ahead?

Yes.

Chill the dough mounds up to 48 hours before baking, or freeze for up to 3 months. Bake from chilled or frozen, adding a couple minutes if frozen.

How do I know when they’re done?

Look for light golden tops and set edges, with a soft, slightly underbaked center. They’ll continue to set on the hot pan during the rest period.

What chocolate is best?

Chunky is best for pockets of melted chocolate.

Use a mix of chips and chopped bars for varied melt and texture.

Can I make them smaller without drying them out?

Yes. Bake 3-ounce scoops for 8–10 minutes. Keep an eye on the centers and pull while they still look a touch underdone.

Why do my cookies spread too much?

The dough may have been too warm, or flour was under-measured.

Chill longer, weigh ingredients if possible, and make sure your butter starts cold.
