It’s fall — and brown butter is basically the anthem of fall in my house. I always keep some tucked in the fridge because it’s one of the best flavors you can add to dessert this time of year. When the air starts to cool and the leaves begin to turn, I go back to the kinds of bakes that feel like wrapping yourself in a blanket — simple, buttery, and nostalgic.
Why You’ll Love It
Double brown butter — in both the cookie dough and the frosting — gives these cookies an extra-deep, nutty caramel flavor that feels like fall in every bite.
Toffee bits melt just slightly as the cookies bake, leaving pockets of crunch and buttery sweetness.
The brown-butter cream-cheese frosting is light, silky, and perfectly balanced — not overly sweet.
Finished with a white-chocolate drizzle and a sprinkle of toffee, these cookies look as good as they taste.
Ingredient Highlights
The star here is brown butter — twice. It adds a warm, toasted flavor to the cookie dough and then shows up again in the frosting, where it deepens the richness and smooths out the tang of cream cheese.
Toffee bits bring caramelized crunch to every bite, and white chocolate ties it all together with a touch of sweetness.
Step Overview
Brown the butter — you’ll need it for both the cookie dough and the frosting later.
Mix and chill the dough to let the brown-butter flavor develop and the texture firm up.
Bake until golden with soft centers that stay chewy even after cooling.
Whip the brown-butter frosting until airy, silky, and light.
Assemble and drizzle with melted white chocolate, finishing with a sprinkle of toffee bits for crunch.
Storage & Serving
These sandwich cookies keep beautifully — and somehow taste even better the next day as the brown-butter flavor deepens and the toffee softens slightly into the cookie. Store them airtight at room temperature for a day or in the fridge up to four days. Serve slightly chilled for clean frosting edges, or at room temperature for soft, gooey centers.
Maybe that’s why sandwich cookies have always been one of my favorite things to bake — double the cookie, extra frosting, and the kind of dessert that feels like a hug. They remind me of being little, standing on a chair helping my Nana roll out pie dough. That memory — the warmth, the rhythm, the scent of butter browning on the stove — is what I try to capture in every fall bake. These cookies are a little soft, a little messy, and completely worth it. Cozy, nostalgic, and gone before you know it.
Double Brown Butter Toffee Sandwich Cookies
Ingredients
Equipment
Method
- Add 225 g (1 cup) unsalted butter to a light-colored saucepan and melt over medium heat. Continue cooking, stirring often, until the butter turns deep amber and smells nutty, about 6–8 minutes. You’ll have about 170 g (¾ cup) after browning due to evaporation — this is normal.
- Pour into a heat-safe bowl and cool for 30 minutes, until thickened and room temperature.
- Measure out 170 g (¾ cup) for the cookie dough and 55 g (¼ cup) for the frosting, keeping the frosting portion covered at room temperature until ready to use.
- In a large bowl, whisk the 170 g (¾ cup) brown butter with 150 g (¾ cup) light brown sugar and 50 g (¼ cup) granulated sugar until glossy and combined.
- Whisk in 1 large egg + 1 yolk, 60 mL (¼ cup) pure maple syrup, and 2 tsp vanilla extract until smooth and slightly thick.
- In a separate bowl, whisk together 285 g (2 cups + 2 Tbsp) all-purpose flour, 1 tsp baking soda, ¼ tsp baking powder, ¾ tsp fine sea salt, and ½ tsp ground cinnamon.
- Fold the dry ingredients into the wet mixture until just combined. Stir in 100 g (¾ cup) Heath toffee bits. The dough should be thick and glossy.
- Scoop about 55 g (just under ¼ cup) of dough per cookie, roll into balls, and coat in extra toffee bits.
- Place dough balls on a tray or plate and chill for 1–2 hours (or up to overnight) to firm for even spreading.
- Preheat the oven to 350°F (177°C). Line a baking sheet with parchment paper.
- Arrange dough balls several inches apart and bake for 10–12 minutes, until edges are golden and centers look soft.
- Cool on the tray for 5 minutes, then transfer to a wire rack to cool completely.
- In a medium bowl, beat 55 g (¼ cup) brown butter and 115 g (4 oz) cream cheese until light and fluffy, about 1–2 minutes.
- Add ½ tsp vanilla extract and a pinch of salt.
- Gradually add 100 g (¾ cup + 1 Tbsp) powdered sugar on low speed until smooth, then beat on medium-high for 1 minute until airy.
- Chill 10–15 minutes if too soft.
- Pair cookies by size. Pipe or spread frosting onto the flat side of one cookie, leaving a small border.
- Gently press a second cookie on top and twist slightly to spread the frosting evenly.
- Drizzle with 40 g (¼ cup) melted white chocolate and sprinkle with extra toffee bits.
- Chill assembled cookies 15 minutes before serving for clean edges.
- For perfectly round cookies, use a cookie cutter or cup slightly larger than each cookie while still warm. Swirl gently to shape.
- You can chill the dough longer than 2 hours — up to overnight if baking the next day. Let sit 10–15 minutes at room temperature before baking.
Notes
- At room temperature: Store in an airtight container for up to 1 day.
- Refrigerated: Keeps up to 4 days. Serve slightly chilled for defined frosting edges, or at room temperature for softer, gooier centers.
- Make ahead: Frosting can be made 1–2 days in advance and stored covered in the refrigerator.
- Freezing: Unbaked dough balls or baked cookies can be frozen for up to 2 months. Thaw dough balls overnight in the refrigerator before baking.
- Flavor tip: These cookies taste even better the next day as the brown-butter flavor deepens and the toffee softens slightly into the cookie.
Follow this recipe to a tee and not only will your house smell amazing, but you won’t be able to stop eating these cookies. The brown butter is key to making these delectable treats and you won’t regret the joy you’ll get out of every bite.
