Description
These brown butter chocolate chip cookies are thick, soft, and chewy with deep caramel-like flavor from toasted butter. The dough includes an extra egg yolk for richness and a touch of milk to replace lost moisture. Plan ahead for two chill times—your patience is rewarded with bakery-style cookies every time.
Ingredients
- 1 cup (16 Tbsp; 226g) unsalted butter
- 1/2 cup (100g) granulated sugar
- 1 cup (200g) packed light or dark brown sugar
- 1 large egg + 1 egg yolk, at room temperature
- 2 teaspoons pure vanilla extract
- 2 and 1/2 cups (313g) all-purpose flour (spooned & leveled)
- 1 teaspoon cornstarch
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 2 Tablespoons (30ml) milk, at room temperature
- 1 and 1/2 cups (270g) semi-sweet chocolate chips
- optional: flaky sea salt, for topping
Instructions
- Brown the butter: Slice the butter into pieces and place in a light-colored skillet. The light colored helps you determine when the butter begins browning. Melt the butter over medium heat and stir or whisk constantly. Once melted, the butter will begin to foam. Keep stirring/whisking. After 5–7 minutes, the butter will begin browning and you’ll notice lightly browned specks begin to form at the bottom of the pan, which are the milk solids toasting. Cook until it is golden in color. Once browned, remove from heat immediately and pour into a heatproof bowl, including all of the browned bits (flavor!). Let cool for 10 minutes, then place in the refrigerator and chill until solid, about 90 minutes. After about 30 minutes, tightly cover the bowl.
- Remove the solidified brown butter from the refrigerator and spoon it into a large bowl (or the bowl of your stand mixer). Using a handheld mixer or stand mixer fitted with a paddle attachment, beat on high speed for 1–2 minutes until smooth and creamy. It may look slightly grainy at first—keep beating and it will come together. If the butter is too firm to cream, let it sit at room temperature for 5–10 minutes. You can also microwave it for 5–8 seconds to slightly soften it, but do not melt it; it should remain solid, just softened enough to beat smoothly.
- Add the brown sugar and granulated sugar and beat on medium-high speed until lightened in color and combined, about 2 minutes. Add the egg, egg yolk, and vanilla extract and beat until combined. Scrape down the sides and bottom of the bowl as needed.
- In a separate bowl, whisk together the flour, cornstarch, baking soda, and salt. Add the dry ingredients to the butter mixture and mix on low speed until just combined. With the mixer running on low, drizzle in the milk and mix until incorporated. The cookie dough will be thick and soft. Add the chocolate chips and mix until evenly distributed.
- Scoop and roll the dough into balls, about 2 Tablespoons or 45g each. Shape them taller rather than wide—almost like a cylinder. This helps the cookies bake up thicker. Place the dough balls on a lined baking sheet or plate, cover, and refrigerate for at least 2 hours or up to 3 days.
- Preheat oven to 375°F (191°C). Line large baking sheets with parchment paper or silicone baking mats. Set aside. Arrange 8 dough balls per baking sheet, spacing them about 3 inches apart. Sprinkle sea salt, if using, on top of the dough balls.
- Bake for 12–14 minutes, or until the edges are lightly golden brown. The centers will look soft when you remove them from the oven. Cool on the baking sheet for 5 minutes. During this time, you can press a few extra chocolate chips into the tops (just for looks!). The cookies will slightly deflate as they cool. After 5 minutes, transfer to a wire rack to cool completely.
- Store in an airtight container at room temperature for up to 5 days.
Notes
- Make Ahead Instructions: You can make the cookie dough and chill it in the refrigerator for up to 3 days. Baked cookies freeze well for up to 3 months. Thaw at room temperature. Unbaked cookie dough balls freeze well for up to 3 months. Bake frozen cookie dough balls for an extra minute, no need to thaw. Read my tips and tricks on how to freeze cookie dough.

- Why Do I Solidify the Browned Butter? Solidifying the browned butter allows you to cream it with the sugars, which creates structure and gives the cookies a thicker texture. Using melted brown butter will produce a thinner, denser, and possibly greasy cookie.
- Extra Egg Yolk: The extra yolk adds richness and chewiness without making the cookies cakey; do not skip.
- Why Add Cornstarch? Cornstarch helps create a softer, thicker cookie by tenderizing the crumb. If needed, you can leave it out.
- Milk: Browning butter reduces moisture, so adding a splash of milk brings that balance back without weighing down the dough. I recommend reduced-fat milk, though whole milk and nondairy milks work in a pinch.
- Oven Temperature Update: Over the years, we’ve found that baking these at 375°F (191°C), slightly warmer than usual, helps set the shape quickly so the cookies stay thicker.
