Brown Butter Toffee Cookies

My soft and chewy brown butter toffee cookies are packed with toffee pieces and flavored with vanilla, brown butter, and sprinkling of sea salt. Never browned butter before? I’ll show you how! Recipe includes a how-to video!

The BEST Toffee Cookies

I first shared these brown butter toffee cookies over 7 years ago. Since then, they’ve remained one of my favorites, a guaranteed-to-please go-to that everyone, without fail, asks me for the recipe for.

The inspiration for these cookies came to me via the cafeteria of the hospital where Zach and I used to work. The original was quite a bit underwhelming–too artificial, dry, and not enough butter flavor–but it provided me with some good starting points for my own creation.

My version is anything but underwhelming; we’re talking slightly crisped exteriors, crunchy milk chocolate toffee bits, and a nutty, buttery flavor in every bite (especially in those soft centers!). These cookies are so good!

Why You’ll Love This Recipe

• Makes a fantastic fall cookie that’s both pumpkin and pumpkin spice free (if you’re not into that kinda thing). Something about the warm, buttery flavor just makes me think of fall in all the best ways. Feel free to make them year-round though–I certainly do!
• Brown butter provides the best, butteriest flavor that complements the toffee add-ins so well. If making brown butter seems intimidating to you, just know that it’s a simple process. I’ll walk you through every step below!
• No chilling or mixer required! Though you can always cover and chill the dough if you would like; this would likely give the cookies an even richer, more buttery flavor. Keep in mind that that the dough gets a bit crumbly when chilled and will need to come to room temperature before you can scoop and bake.
• Soft and chewy texture that lasts for days, thanks to my tried-and-true baking technique. On the other hand, if you like crunchy cookies, try my butter crunch cookies!

What You Need

• Brown sugar. I recommend a blend of dark and light brown sugar, though you can use all light brown sugar if that’s all you have on hand.
• Toffee bits. Use the crushed milk chocolate toffee bits (Heath bar bits). You can usually find these near chocolate chips in the baking aisle of your grocery store.
• Vanilla. A hefty pour of vanilla (half a tablespoon!) adds SO much flavor to these cookies. I love using homemade vanilla extract in this recipe; if you haven’t made your own yet, you need to!
• Salt. While we are using regular table salt in the dough, I recommend sprinkling flaky sea salt on the cookies just after removing them from the oven. This really intensifies all of the already robust flavors of these brown butter toffee cookies.
• Butter. We’re using a full cup (two sticks) of butter today. We’ll brown this and let it cool completely before adding it to the dough. Note that unless otherwise indicated, you should measure your butter before browning it.

SAM’S TIP: Since we are using room temperature butter, it’s best if you use room temperature eggs as well. I have a trick to quickly bring eggs to room temperature if you forget to set yours out ahead of time.

How to Make Brown Butter Toffee Cookies

Brown the butter

Browning the butter is the key to adding truly incredible, jaw-dropping flavor to this recipe. It’s a key ingredient in my brown butter frosting, brown butter chocolate chip cookies, and pistachio cake and it’s every bit as important here, too.

To make it, add the butter to a light-bottomed saucepan over medium-low heat. Once melted, increase the heat to medium and stir constantly as the butter bubbles, foams, and pops. Pay close attention, and once you notice a toasty aroma and see brown bits forming on the bottom of the pan, remove from the heat and pour into a heat-proof bowl. You’ve just made brown butter!

Make sure to let the butter cool for 25-30 minutes before adding your other ingredients, otherwise you run the risk of melting your sugars and creating a seriously runny, unusable dough.

Make the dough

The dough comes together like most standard doughs. Once the butter has cooled (completely! Make sure the bottom of the bowl that it’s cooling in doesn’t feel even a little warm), you can add the sugars then the egg and vanilla.

Whisk the dry ingredients together separately then gradually fold it into the wet ingredients. This is a stiff dough, so I do this in 3-4 parts for the easiest combining.

Fold in your toffee bits until evenly incorporated, then you’re ready to scoop! No more chilling needed, you waited long enough for the browned butter to cool so you’re ready to go now!

Bake the cookies

Scoop and roll the dough into 1 ½ tablespoon balls, then place on parchment lined baking sheets.

Bake until the edges are just starting to turn golden brown (the centers will still look a bit underdone, then remove and sprinkle with sea salt (you need to do this while the cookies are still warm, so it sticks). The cookies will continue baking outside the oven on the hot cookie sheets. This is my favorite trick for soft and chewy cookies that stay soft for days!

SAM’S TIP: The toffee bits tend to stick to the baking sheets as the cookies cool, so I like to gently wiggle the cookies with a spatula after they’ve been out of the oven for a few minutes.

Frequently Asked Questions

I highly recommend that you re-heat your toffee cookies briefly in the microwave before enjoying (about 9-seconds per cookie, in my microwave). Warm cookies are the best cookies!
