Why You’ll Frickin’ Love these Chocolate Cookies
- Cold Butter Magic: Starting with cold, cubed butter creates a firm dough that resists spreading, giving the cookies their jaw-dropping height and gooey center.
- Brown Sugar Depth: Using more brown sugar than white lends a rich, caramel flavor and chewy texture that sets these Levain-style chocolate chip cookies apart.
- Chocolate Combos: Mixing bittersweet and semi-sweet chocolate means every bite is studded with puddles and chunks, making the cookie both sophisticated and fun.
- Cornstarch Tenderness: A spoonful of cornstarch softens the crumb, ensuring the inside stays plush and tender for days instead of turning dry or cakey.
- High-Heat Baking: Blasting the cookies at 400°F lets the edges set quickly while the thick middles stay molten and soft, a signature Levain-style move.
Ingredient Notes for Levain-Style Chocolate Chip Cookies
- Unsalted Butter: Cold and cubed, creaming it cold helps prevent over-spreading, holding each cookie extra tall and rich.
- Brown Sugar: The backbone of the chew. Use packed light brown for classic flavor, or dark for deeper molasses notes.
- Granulated Sugar: Balances sweetness and helps the outside get crisp and golden.
- Large Eggs: Room temperature eggs mix smoother and give a thick, uniform dough.
- All-Purpose Flour: Regular AP flour ensures strength so cookies don’t collapse; weigh flour for best results.
- Cornstarch: Just a little makes the crumb ultra tender without cakiness.
- Baking Powder + Baking Soda: This combo gives a strong lift and just enough spread so cookies set tall and dense, not dry.
- Kosher Salt: Essential for rounding out all the rich sweet notes, don’t skip it.
- Bittersweet + Semi-Sweet Chocolate: Use roughly chopped bars or large wafers for dramatic gooey pockets. A mix delivers the best flavor and melty pools.
- Walnuts: Coarsely chopped and lightly toasted for essential crunch and buttery depth in every bite.
My Tips for the Best Results
- Keep It Chunky: When portioning, pile the dough high and rough rather than rolling smooth balls. This gives you bakery-style valleys and irresistible crispy bits.
- Weigh Ingredients: For consistently thick results, use a kitchen scale to measure flour and other dry ingredients. Eyeballing can lead to cookies that are too flat or cakey.
- Mix Chocolate for Drama: Use both bittersweet and semi-sweet chocolate, roughly chopped, for gooey pockets and a blend of deep chocolate flavor.
- Chill Before Baking: Always chill your portioned dough. Cold dough hits the oven running, keeping cookies tall and thick instead of spreading out.
- Oven Visuals Matter: Don’t just trust the timer, watch for golden edges and slightly underdone centers. Letting cookies rest on the hot pan creates the perfect gooey core.
Forming and Baking Giant Levain-Style Cookies
If you want that classic Levain-style look and texture, a few signature moves in shaping and baking make all the difference.
- Portion Generously: Scale out 110 grams (about 1/3 cup) of dough per cookie. Bigger mounds mean gooey, sky-high centers and a dramatic bakery look.
- Stack Roughly: Don’t smooth the dough, leave it craggy and tall to maximize crispy bits and create those signature ridges and valleys.
- Quick Chill, Big Impact: Pop the trays in the fridge for at least 30 minutes to set the butter and firm up the dough for the thickest result.
- Bake from Cold: Move the chilled dough straight into a fully preheated hot oven. The temperature shock helps the cookies spring up tall and keeps the centers soft.
- Let Them Rest: Leave cookies on the baking sheet for 10 minutes after baking to finish setting the gooey centers and prevent tearing when transferring.
Mastering these shaping and chilling tricks guarantees every cookie explodes with Levain-style thickness and a luscious, tender core.
Ingredients for Levain-Style Chocolate Chip Cookies
- 227 grams unsalted butter (cold, cut into 1/2-inch cubes)
- 200 grams light brown sugar (packed)
- 120 grams granulated sugar
- 2 large eggs (room temperature)
- 2 teaspoons vanilla extract
- 420 grams all-purpose flour
- 2 tablespoons cornstarch
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1 teaspoon kosher salt
- 175 grams bittersweet chocolate (roughly chopped (~70% cacao))
- 175 grams semi-sweet chocolate (roughly chopped (~55% cacao))
- 150 grams walnuts (toasted and coarsely chopped)
How to Make Levain-Style Chocolate Chip Cookies
- STEP 1). Cream cold butter and sugars until just fluffy In the bowl of a stand mixer fitted with a paddle, combine cold, cubed butter, brown sugar, and granulated sugar. Mix on medium speed for 2½-3 minutes, scraping the bowl once, until the mixture just barely fluffs up and lightens, aim for visible lumps of butter, not a smooth paste. This keeps air in the dough for ultimate height.
- STEP 2). Mix in eggs and vanilla to blend Add eggs and vanilla extract all at once and beat on low just until incorporated, about 30 seconds. Stop as soon as the eggs disappear, overmixing at this stage will warm the butter too much and reduce the cookies' thickness.
- STEP 3). Add dries and mix until crumbly, then finish by hand Whisk together flour, cornstarch, baking powder, baking soda, and salt. Add to the mixer and pulse or mix on low until mostly combined and big craggy bits form, about 30-40 seconds. Finish folding gently by hand with a spatula for a few strokes, just until you see no dry streaks.
- STEP 4). Fold in chocolate and walnuts for chunky pockets Add all chopped chocolate and walnuts to the dough. Use a spatula to gently fold in by hand, working just until the big chunks look evenly distributed, don’t worry if a few streaks of dry flour remain.
- STEP 5). Portion and chill for ultimate thickness Line two baking sheets with parchment. Scoop the dough into 110g mounds (about 1/3 cup), stacking high and rough, not round. Place 6 cookies per sheet, leaving plenty of space. Chill the trays uncovered in the fridge for 30-40 minutes until firm and cold to the touch.
- STEP 6). Bake in a hot oven for crispy edges and a gooey core Preheat the oven to 400°F (205°C). Bake chilled dough straight from fridge for 12-14 minutes, rotating pans halfway. Cookies should look set at the edges, tawny-golden, and a little doughy in the very center. Don’t overbake, residual heat will finish them.
- STEP 7). Cool on baking sheet, then finish on rack Let cookies rest on the hot sheets for at least 10 minutes, this sets the gooey centers and prevents tearing. Use a wide spatula to carefully move cookies to a wire rack to cool completely or until still slightly warm for ultra-gooey enjoyment.
Storage and Freezing
- Storage: Store cookies up to 4 days in an airtight container at room temperature; keep parchment between layers.
- Freezing: Freeze baked or unbaked dough mounds on a tray, then transfer to a freezer bag for up to 2 months.
- Baking from frozen: Bake frozen dough at 400°F, adding 2-3 extra minutes, check for golden edges and set tops.
- Rewarming: Warm cooled cookies in a 300°F oven for 3-4 minutes for that melt-in-the-middle bite.
Frequently Asked Questions
What gives Levain-style chocolate chip cookies their signature thick texture?
Levain-style chocolate chip cookies owe their signature thickness to a unique combination of cold butter, a high flour ratio, and large, rough dough mounds. The cold butter keeps the dough firm, reducing spread as the cookies bake, while the generous portions and craggy stacking create dramatic height and a substantial, gooey core. Chilling the dough before baking is also a key step, locking in moisture and helping the cookies hold their shape in the oven.
To get that perfect texture, it's essential not to overwork the dough and to bake the cookies at a high temperature. This technique sets the edges quickly and preserves a molten, almost underbaked middle, exactly what makes Levain-style cookies so irresistible! If you follow these steps, you’ll enjoy those sky-high, chewy centers every time.
How do I know when these massive cookies are done baking?
The best way to check for doneness is to look for deeply golden, set edges while the very centers still appear slightly underbaked and pale, just not shiny or wet. You want the middle to look almost doughy, as the cookies will keep cooking from residual heat after you remove them from the oven. That gooey core is the hallmark of a perfect Levain-style cookie!
Once baked, always let the cookies rest on the hot sheet for at least 10 minutes. This crucial step allows the centers to finish setting and prevents the cookies from tearing or collapsing when moved. Patience pays off with bakery-worthy results and gooey, dreamy interiors.
Do I have to use both dark and semi-sweet chocolate?
Using both dark and semi-sweet chocolate creates a more nuanced flavor profile and those dramatic, gooey pockets that define true Levain-style chocolate chip cookies. Bittersweet chocolate adds depth and a touch of sophistication, while semi-sweet brings the classic melty sweetness everyone loves. Together, they make each bite a chocolate adventure!
If you only have one type on hand, you can still make delicious cookies, but I highly recommend using both for the most authentic and indulgent result. The mix also gives you beautiful, varied chocolate melt and texture throughout the cookie.
Can walnuts be omitted for a nut-free version?
You can leave out the walnuts, and the cookies will still bake up thick, rich, and full of chocolate. Walnuts contribute crunch and balance the sweetness, so removing them produces a slightly softer, more chocolate-forward cookie.
Keep the remaining ingredient quantities unchanged. Judge doneness by the golden, set edges and softer centers rather than relying only on the timer. For someone with a nut allergy, check every ingredient label and prevent cross-contact during preparation.
Why does this dough call for cornstarch?
Cornstarch is a little secret weapon in these Levain-style chocolate chip cookies! It helps tenderize the crumb by reducing gluten formation, resulting in cookies that are plush and melt-in-the-middle soft without being heavy or cakey. The cornstarch works with the flour and eggs to thicken the dough just enough for that signature chewy, gooey center.
Adding cornstarch also helps your cookies stay soft for days, keeping them bakery-fresh even after a day or two. It’s a small ingredient that makes a big difference in texture, so don’t skip it if you want the ultimate cookie experience.
How much dough should I use for each Levain-style cookie?
Each Levain-style cookie should be a hefty 110 grams, or about a 1/3 cup scoop, no tiny cookies allowed! This generous portion is essential for achieving the dramatic height and gooey center that defines the Levain style. Using a scale is the best way to ensure each cookie bakes up consistently thick and substantial.
Shaping the dough into tall, rough mounds (rather than smooth balls) also helps create those iconic bakery-style ridges and valleys. This size and shape are what make every bite decadent and bakery-worthy, perfect for sharing (or keeping all to yourself)!
