My Brown Butter Toffee Chocolate Chip Cookies are big and soft, with lots of chocolate and homemade toffee chips inside. If you're on the hunt for an incredible chocolate chip cookie recipe, this one is top-notch!

This recipe has two parts: a quick batch of toffee chips and a brown butter cookie dough. You mix the dough in one bowl by hand, and there's no need to chill it.
I've baked many chocolate chip cookies, but these are my go-to when I want something a little different. Browned butter adds a nutty, toasty flavor, and the homemade toffee has so much buttery, caramel flavor. You're going to love it!
Here's Why You'll Love This Recipe
- They have a deep flavor. Brown butter gives them a toasty, nutty taste you don't get from regular butter.
- The toffee is homemade, so the chips are crisp and buttery. They're even better than store-bought bits.
- They're chewy, with edges that are set and centers that stay moist. Cornstarch helps keep them tender.
- You only need one bowl for the dough. Just stir everything together by hand. No mixer needed.
- They look like bakery cookies. Use a cookie cutter to shape them, then add toffee and sea salt on top.
- You'll get 12 big cookies, using 3 tablespoons of dough for each.
Ingredients You'll Need
The recipe card at the bottom of the post contains the full list with all of the amounts. Refer to that when you're cooking.

For the toffee chips
- Unsalted butter: The base of the toffee.
- Granulated sugar: Cooks into the caramelized toffee.
- Water: Helps the sugar dissolve evenly at the start.
- Kosher salt: Balances the sweetness. Use a scant amount.
- Vanilla bean paste or vanilla extract: Add this at the end. Paste gives you vanilla flecks, but extract works just as well.
For the cookies
- Unsalted butter: Browned to give the cookies their nutty flavor.
- Light brown sugar: Adds moisture and a caramel taste. Pack it lightly.
- Granulated sugar: Adds sweetness and helps the edges crisp.
- Large egg and large egg yolk: The yolk adds richness and keeps the cookies chewy.
- Vanilla bean paste or vanilla extract: Rounds out the flavor.
- All-purpose flour: The structure of the cookie.
- Cornstarch: Makes the cookies soft and tender.
- Baking soda: Helps the cookies spread and rise. Use a scant ½ teaspoon.
- Kosher salt: Brings out the butter and chocolate.
- Chocolate chips: I prefer bittersweet, but any kind works.
- Flaky sea salt (optional): Sprinkle some on top to highlight the toffee and chocolate.

Step 1: Make the toffee chips
Line a baking sheet with parchment paper and set it aside.
In a medium, heavy-bottomed pot over medium heat, combine the butter, sugar, water, and salt.
Attach a candy thermometer to the side of the pot.
Let the mixture come to a boil and start to turn brown.


Keep cooking and stirring until the thermometer reads 300°F.
Take the pot off the heat, stir in the vanilla, and pour the hot toffee onto the prepared pan.
Let the toffee cool and harden, then break it into pieces. (Here's more on how to make toffee.)


Step 2: Brown the butter
Preheat the oven to 375°F and line baking sheets with parchment paper.
Melt the butter in a large, light-colored skillet over medium-low heat until it bubbles. The light pan helps you see the color change.
Once the bubbling slows, cook the butter gently until it turns toasty brown and smells fragrant. Swirl the pan occasionally so it heats evenly. (See how to brown butter for more detail.)

Step 3: Mix the dough
Pour the brown butter into a large, heat-safe bowl. Stir in the brown sugar and granulated sugar.

Stir in the egg until it's fully combined.
Add the egg yolk.


Add the vanilla and stir until combined.

Stir in the flour, cornstarch, baking soda, and salt.

Fold in the chocolate chips and about two-thirds of the toffee chips.

Step 4: Bake
Use a trigger scoop to portion 3 tablespoons of dough for each cookie onto the prepared baking sheets. Leave an inch or two between them so they have room to spread.


Bake for 6 to 10 minutes, until the edges are set but the centers are still very moist.
While the cookies are still warm, use a large round cookie cutter or a small bowl to gently shape them into circles.

Top the cookies with the rest of the toffee chips and a sprinkle of flaky sea salt, if you like.

Let the cookies cool completely on the baking sheets.
Helpful Tips and Tricks
- Use a light-colored skillet so you can see the butter change from yellow to golden brown and avoid burning it.
- Watch the butter closely. Remove it from the heat when it smells nutty and toasty, and pour it out right away so it doesn't keep cooking.
- Use a candy thermometer and cook the toffee to 300°F for a crisp, snappy texture.
- Pour the toffee onto parchment paper. It hardens quickly and is easy to lift and break.
- Set aside about one-third of the toffee chips to use on top of the cookies.
- Don't overbake the cookies. Take them out when the edges are set, but the centers are still moist. They'll finish setting on the pan.
- Shape the cookies while they're still warm, since the cutter trick only works when they're soft.
- Leave an inch or two between each dough ball so the cookies have room to spread.
- Let the brown butter cool for a few minutes before adding the egg, so the egg doesn't cook in the bowl.
- Use any chocolate you like. Bittersweet balances the toffee, but milk or semisweet chocolate works too.
