Why This Recipe Works

Browned Butter Base: Browning half the butter builds nutty, caramel depth without sacrificing the chew you get from melted fat.
Two Sugars, Two Textures: Dark brown sugar for moisture and chew, white sugar for crisp edges—balanced for cookie nirvana.
Chill, But Don’t Over-Chill: A 30-minute rest hydrates flour and prevents spread, yet keeps the center gooey.
Chocolate Discs > Chips: Valrhona fèves melt into puddles; chips stay chunky—using both equals drama in every bite.
Flaky Sea Salt Finish: A light sprinkle heightens sweetness and cuts richness, making you reach for “just one more.”
Under-Bake by 2 Minutes: Carry-over heat sets centers; pull when edges are golden and centers still jiggle.

Ingredients You'll Need

Great cookies start with great groceries. Below is the cast list, plus what to look for on the shelf and what you can swap in a pinch.

Unsalted Butter: European-style (82% fat) browns more quickly and tastes extra luxe. If you only have salted, omit the ½ tsp kosher salt later.

Dark Brown Sugar: The molasses content keeps centers soft. In a pinch, mix 1 cup white sugar with 1 ½ Tbsp molasses.

Vanilla Bean Paste: Paste speckles the dough like caviar; extract works, but you’ll lose the glamour shot.

Espresso Powder: Optional, but it amplifies chocolate the way a great soundtrack amplifies a movie scene. Decaf works fine.

Large Eggs + 1 Yolk: The extra yolk emulsifies the browned butter and adds chew.

Bread Flour + Cake Flour: A 70/30 blend gives you the chew of a bakery cookie without being cakey. All-purpose is acceptable; swap 2 Tbsp per cup with cornstarch for tenderness.

Bittersweet Chocolate (70%): Look for bars with cacao origin labels—single-origin Madagascar brings red-berry notes that sing against salt.

Flaky Sea Salt: Maldon or Falksalt. The pyramid crystals crunch rather than dissolve, giving tiny pops of salinity.

How to Make Warm Chocolate Chip Cookies With Sea Salt

Brown the Butter

Place ½ cup (113 g) butter in a stainless skillet over medium heat. Swirl constantly until the milk solids turn chestnut brown and the aroma smells like toasted hazelnuts, 4–5 minutes. Immediately scrape into a heat-proof bowl to stop cooking; chill 15 minutes while you prep everything else.

Whisk Dry Team

In a medium bowl, whisk 1 ¾ cup bread flour, ¾ cup cake flour, 1 tsp baking soda, ½ tsp baking powder, and ½ tsp kosher salt. Aerating now prevents dense cookies later.

Cream Remaining Butter & Sugars

In a stand mixer fitted with the paddle, beat the remaining ½ cup softened butter with 1 cup dark brown sugar and ½ cup white sugar on medium-high for 2 minutes until fluffy. The mixture should look like whipped caramel frosting.

Stream in Browned Butter

With mixer on low, pour the cooled (but still liquid) browned butter slowly. Increase speed and beat 1 minute until satiny. The batter will darken to butterscotch hues.

Emulsify Eggs & Vanilla

Beat in 2 large eggs, 1 yolk, 2 tsp vanilla paste, and ½ tsp espresso powder. Mix until the ribbon stage—when you lift the paddle, the batter should ribbon back onto itself for 3 seconds.

Fold in Flours

Reduce speed to low; add dry ingredients in three additions, mixing just until the last streak disappears. Overmixing develops gluten and gives you hockey pucks.

Load the Chocolate

Reserve ¼ cup chocolate for topping. Fold in 8 oz bittersweet fèves and 4 oz chips by hand with a flexible spatula so they stay intact.

Chill 30 Minutes

Cover bowl with beeswax wrap; refrigerate 30 minutes. This hydrates flour and prevents excess spread while keeping centers molten.

Scoop & Top

Use a #40 disher (1 ½ Tbsp) to drop mounds 2 inches apart on parchment-lined sheets. Press reserved chocolate on top for Instagram-worthy puddles.

Bake & Salt

Bake at 350 °F (175 °C) on center rack 10–11 minutes, until edges are golden and centers look underdone. Immediately sprinkle with flaky sea salt. Cool on sheet 5 minutes, then transfer to a rack. Serve warm for peak gooeyness.

Expert Tips

Temperature Matters

Browned butter should be fluid but not hot—around 90 °F. Too warm and you’ll scramble the eggs.

Overnight Chill

For deeper toffee notes, refrigerate scooped dough up to 48 hours. Bring to room temp 20 minutes before baking.

Cookie Size

For bakery-style 4-inch cookies, use a #20 disher and add 2 minutes bake time.

Hydration Fix

If dough feels crumbly after chill, knead once or twice with lightly damp hands—humidity varies.

Reheat Like a Pro

Revive day-old cookies at 300 °F for 3 minutes with a tiny water splash in the oven for steam.

Gluten-Free Swap

Replace flours with 2 ½ cups King Arthur Measure-for-Measure plus ¼ tsp xanthan gum.

Variations to Try

Storage Tips

Room Temperature: Once completely cool, store in an airtight tin with a slice of bread; the bread sacrifices its moisture so cookies stay soft 4 days.

Freezer (Dough): Scoop onto a sheet, freeze solid, then transfer to a zip bag for 3 months. Bake from frozen, adding 1 extra minute.

Freezer (Baked): Wrap pairs back-to-back in parchment, then foil; freeze up to 2 months. Thaw 10 minutes at room temp or reheat per tip above.

Make-Ahead Party Packs: Layer frozen dough balls in mason jars with parchment squares; tie on baking instructions for last-minute gifts.

Frequently Asked Questions

You can, but cookies will spread less and taste more like molasses. Swap 2 Tbsp brown for white to regain some crisp.

Likely over-measured flour or over-mixed dough. Spoon flour into cups and level, or better, weigh: 280 g total.

Absolutely. Use a larger skillet for browning butter, and bake in batches on separate racks, switching halfway.

Coarse kosher works, but crush it lightly between fingers first so granules aren’t too aggressive.

Under-bake by 90 seconds, cool, wrap pairs in plastic, then bubble mailers with a cold pack; choose 2-day shipping max.

Yes—use a kitchen scale for accuracy; halving an egg yolk is tricky, so whisk one yolk and use 1 ½ Tbsp.
