Brown Butter Toffee Cookies

WANT TO SAVE THIS RECIPE?

If there’s one cookie recipe I keep coming back to, it’s these Brown Butter Toffee Cookies. They’ve got everything I love—crisp edges, soft centers, rich nutty flavor from the browned butter, and melty pools of chocolate paired with buttery toffee bits. I first made them on a whim, curious about how browning butter might elevate a classic cookie. Now? They’re a permanent part of my baking rotation.

Each bite has a deep caramelized flavor, thanks to the brown sugar and toffee, with just a touch of sea salt on top for contrast. They’re the kind of cookies that disappear fast, whether it’s for a holiday cookie swap, casual get-together, or just a night when I’m craving something warm and sweet. Once you make them, I think you’ll get why they’ve become a personal favorite.

Why You’ll Love These Brown Butter Toffee Cookies

These cookies are a beautiful balance of flavors and textures. The browned butter adds a rich, nutty depth that instantly makes them taste gourmet. The toffee pieces melt slightly into the dough, creating gooey, chewy pockets of sweetness. And the edges crisp up just right while the center stays soft and tender. They’re easy enough for a weeknight treat but impressive enough to share (if you can part with them).

What Kind of Toffee Should I Use?

I like using chopped-up toffee bars like Heath or Skor, but you can also use pre-made toffee bits found in the baking aisle. The key is to avoid overly hard chunks that won’t melt slightly in the oven. You want bits that soften just enough to become part of the cookie, not ones that stay rock solid.

Options for Substitutions

If you’re short on ingredients or want to tweak the flavor, there’s room to play here:

• No toffee? Use butterscotch chips or caramel bits.
• Brown sugar substitute: Coconut sugar works well and gives a slightly deeper molasses note.
• Gluten-free version: Use a 1:1 gluten-free baking flour blend.
• Chocolate: Dark, semi-sweet, or even chopped milk chocolate bars will all work—just avoid chips if you want that dramatic chocolate puddle effect.
• Egg-free? Try a flax egg (1 tbsp ground flax + 3 tbsp water) for a softer cookie.

Ingredients for Brown Butter Toffee Cookies

• Unsalted Butter – Browning the butter intensifies its flavor, adding a nutty, caramel-like richness that transforms the entire cookie.
• Brown Sugar – Essential for chewiness and depth; it enhances the molasses notes and complements the toffee perfectly.
• Granulated Sugar – Balances the moisture from the brown sugar and adds the right amount of crispness to the edges.
• Egg + Egg Yolk – The extra yolk adds richness and helps maintain that soft, chewy texture.
• Vanilla Extract – Rounds out the flavor and adds warmth that pairs beautifully with browned butter and toffee.
• All-Purpose Flour – Provides structure and chew; the right amount ensures the cookies hold their shape without being too cakey.
• Baking Soda – Helps the cookies spread just the right amount while staying light.
• Salt – Essential for balance; it cuts the sweetness and enhances the overall flavor.
• Chopped Toffee Bits – The star ingredient that melts into pockets of sweet, buttery crunch.
• Chopped Dark Chocolate or Chocolate Chunks – Adds contrast with its bittersweet richness and makes the cookie even more indulgent.
• Flaky Sea Salt (optional) – A final touch that elevates every bite with a savory sparkle.

Step 1: Brown the Butter

Start by melting your butter in a saucepan over medium heat. Stir frequently until the butter foams, turns golden, and smells nutty. This should take about 5–7 minutes. Once browned, remove it from heat and let it cool for 10 minutes before using.

---

Step 2: Mix the Sugars and Butter

In a large mixing bowl, combine the cooled browned butter with the brown sugar and granulated sugar. Mix until well combined—the texture should be thick and glossy.

---

Step 3: Add Eggs and Vanilla

Add the egg and extra yolk, one at a time, mixing well after each addition. Stir in the vanilla extract. The mixture should look creamy and slightly thickened.

---

Step 4: Combine Dry Ingredients

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually mix the dry ingredients into the wet mixture, just until combined. Be careful not to overmix.

---

Step 5: Fold in the Toffee and Chocolate

Use a spatula to gently fold in the chopped toffee bits and chocolate chunks. Make sure they’re evenly distributed throughout the dough.

---

Step 6: Chill the Dough

Cover the bowl with plastic wrap and refrigerate for at least 1 hour, or up to 24 hours. Chilling the dough deepens the flavor and prevents overspreading.

---

Step 7: Preheat and Prepare Baking Sheet

Preheat your oven to 350°F (175°C). Line your baking sheet with parchment paper or a silicone baking mat.

---

Step 8: Scoop and Bake

Scoop dough balls (about 2 tablespoons each) onto the prepared sheet, spacing them 2 inches apart. Bake for 10–12 minutes, or until the edges are golden brown and the centers look just set.

---

Step 9: Finish with Sea Salt

Right after baking, sprinkle the cookies with flaky sea salt if using. Let them rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

How Long to Prepare Brown Butter Toffee Cookies

Prep Time: The preparation process takes about 25–30 minutes. Browning the butter is the most time-consuming step in the prep, but it’s also what makes these cookies so special. Once the butter is cooled, mixing the dough comes together quickly.

Chilling + Baking Time: The dough should chill for at least 1 hour. This step helps concentrate the flavor and improves the cookie’s structure. Baking takes 10–12 minutes per batch, so allow some extra time if you’re baking multiple trays.

Tips for Perfect Brown Butter Toffee Cookies

• Don’t skip browning the butter – It adds the signature nutty depth that sets these cookies apart.
• Cool the browned butter before adding it to the sugar; hot butter can scramble the eggs.
• Chill the dough to prevent spreading and intensify flavor.
• Use chopped chocolate bars instead of chips for those melty pools.
• Sprinkle with sea salt right after baking for a contrast that elevates the sweetness.

Watch Out for These Mistakes While Cooking

• Overbaking: Cookies should look slightly underdone in the center when you pull them out; they’ll continue baking as they cool.
• Using hot butter too soon: This can ruin the texture and consistency of your dough.
• Not measuring flour correctly: Too much flour will result in dry cookies. Spoon and level instead of scooping.
• Skipping chill time: Warm dough spreads too much and loses its thick, chewy texture.
• Using old baking soda: If your baking soda isn’t fresh, the cookies won’t rise or spread properly.
