Ingredients You’ll Need

Ingredients You’ll Need
Creating these Brown Butter Brookies starts with some simple yet essential ingredients. Each component plays a vital role, whether it’s building rich flavor, tender texture, or that perfect golden color you can’t resist.
- Salted butter: The foundation for both layers, butter adds richness and enhances browning in both cookie dough and brownie batter.
- Brown sugar: Adds moisture and deep caramel notes to your cookie dough, giving it that chewy, soft texture we all love.
- Granulated sugar: Balances sweetness in both cookie and brownie components while helping create a slight crisp on the cookies’ edges.
- Large eggs: Provide structure and moisture, ensuring the brookies hold together with a tender crumb.
- Vanilla extract: Brings warmth and rounds out the deep chocolate flavor.
- All-purpose flour: The backbone of both cookie and brownie doughs, supplying just the right amount of structure.
- Baking soda and baking powder: Create the perfect lift and tenderness, especially in the cookie layer.
- Salt: Enhances all flavors and balances the sweetness beautifully.
- Chocolate chips: Essential pockets of molten chocolate that make every bite luscious and dreamy.
- Semi-sweet chocolate: Melted into the browned butter for an intensely fudgy brownie layer.
- Vegetable oil: Adds moisture and softness to the brownie batter.
- Cocoa powder: Delivers the rich chocolate taste that forms the soul of the brownies.
- Powdered sugar: Integrates smoothly for sweetness and helps create that shiny brownie top.
- Espresso powder (optional): A tiny boost that intensifies the chocolate notes without tasting like coffee.
- Flaky sea salt (optional): The perfect finishing touch to make those chocolate flavors pop.
How to Make Brown Butter Brookies
Step 1: Make the Chocolate Chip Cookie Dough
Start by melting the butter in a large mixing bowl until it’s fully liquefied. Whisk in both brown and granulated sugars until smooth and fluffy. Then add your eggs and vanilla extract, whisking for about 30-45 seconds until everything is perfectly combined. In a separate bowl, mix your dry ingredients – flour, baking soda, baking powder, and salt – then stir them into your wet mixture. Fold in those chocolate chips last for fun melty pockets. Divide this cookie dough evenly in half; one half you’ll press into your prepared pan right away, and the other half will wait for later when everything comes together.
Step 2: Brown the Butter
This step takes those brownies to a whole new level. Place the salted butter in a medium saucepan over medium heat. As it melts, keep stirring so it doesn’t burn. The butter will foam and bubble, then gradually transform into a golden brown with a heavenly nutty aroma—which usually takes about 3 to 6 minutes. This nutty browned butter flavor is what makes Brown Butter Brookies unforgettable, so don’t rush this part!
Step 3: Prepare the Brownie Batter
Once your butter is browned, stir in chopped semi-sweet chocolate until it melts completely and blends smoothly with the butter. Whisk in vegetable oil and cocoa powder, then let the mixture cool briefly so it doesn’t scramble your eggs. In a separate bowl, whisk together eggs, egg yolk, and granulated sugar until the sugar dissolves and the mixture is silky smooth—test by rubbing a bit between your fingers. Add powdered sugar, vanilla extract, and salt, whisking gently. When the chocolate mixture has cooled enough, combine it into the egg mixture, folding in flour, espresso powder, and chocolate chips last for extra gooey pockets of chocolate. This rich, deep chocolate batter forms the iconic brownie layer of your Brown Butter Brookies.
Step 4: Assemble Your Brookies
Now comes the fun part! Spread just over half of your brownie batter evenly in the bottom of your lined 9×13 pan. Take that first half sheet of cookie dough you pressed out earlier and lay it directly on top of the brownie layer—remove the parchment paper underneath as you gently transfer it. Spread the remaining brownie batter on top of the cookie dough, smoothing it out for an even layer. Then shape the remaining cookie dough into thick discs and scatter these on top, making sure to press down lightly. If there are any bare spots, tuck in extra chocolate chips for an even more decadent bite.
Step 5: Bake to Golden Perfection
Pop the assembled Brookies into your preheated 350°F oven and bake for 38 to 44 minutes. You’re looking for golden cookie edges and a shiny, slightly crackled brownie surface. A toothpick inserted into a brownie spot should come out with moist crumbs, never wet batter—this ensures fudgy but fully baked brownies. Remember not to overbake, because these beauties are best when soft and gooey!
How to Serve Brown Butter Brookies
Garnishes
A sprinkle of flaky sea salt on warm Brown Butter Brookies adds a sophisticated little pop that balances the sweetness and amplifies chocolate’s richness. You could also dust with a bit of powdered sugar for a pretty presentation, or drizzle some melted chocolate for extra indulgence. Fresh berries on the side provide a juicy contrast that brightens every bite.
Side Dishes
Brown Butter Brookies shine all on their own but pairing them with a scoop of creamy vanilla ice cream creates a classic warm-and-cold sensation that’s pure magic. For a decaf twist, serve alongside a mug of rich hot chocolate or a lightly brewed herbal tea, which complements the nutty, sweet notes without overpowering them.
Creative Ways to Present
Slice your Brown Butter Brookies into bite-sized squares and skewer them with fruit or marshmallows to make elegant dessert kabobs. You can also layer chunks between layers of whipped cream or pudding for an irresistible trifle, or sandwich them with your favorite ice cream for custom Brown Butter Brookie ice cream sandwiches! These creative takes make sharing this favorite treat even more fun.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, keep your Brown Butter Brookies in an airtight container at room temperature for 3 to 4 days. This helps them maintain their perfect balance of chewy cookie and fudgy brownie texture without drying out. For best enjoyment, warm slices slightly before serving for that just-baked feeling.
Freezing
Brown Butter Brookies freeze wonderfully and make a great make-ahead dessert. Wrap individual slices or the whole pan tightly in plastic wrap, then foil, and freeze for up to 2 months. When you’re ready to indulge, thaw overnight in the fridge or warm gently in the microwave.
Reheating
Reheat Brookies gently in the microwave for about 15 to 20 seconds to bring back that freshly baked gooey softness without toughening the edges. Alternatively, a quick warm-up in a low oven (around 300°F) for 10 minutes will help maintain a crispy top with a melty inside. Either way, reheated Brown Butter Brookies taste just as incredible as the day they came out of the oven.
FAQs
Can I use salted butter for the cookie and brownie batter?
Yes! The recipe calls for salted butter to enhance flavor, but if you prefer unsalted butter, just add a pinch more salt to compensate. Salt really helps balance the sweetness and deepens the overall flavor of Brown Butter Brookies.
Why is browning the butter important?
Browned butter has a rich, nutty taste that adds depth and caramel-like complexity, which really elevates the brownies in these brookies. Skipping this step means missing out on a big flavor boost.
Can I make this recipe gluten-free?
Absolutely! Substitute all-purpose flour with a 1:1 gluten-free baking flour blend that contains xanthan gum. Just watch the texture as gluten-free flours can behave a little differently, but you’ll still get delicious Brown Butter Brookies.
How do I get the cookie layer to bake evenly with the brownies?
Pressing the cookie dough evenly in your pan and spreading the brownie batter smoothly helps ensure even baking. Using parchment paper when transferring the cookie dough makes it easier to handle and prevents uneven layering.
Can I make Brown Butter Brookies ahead for a party?
Definitely! These hold up well, so you can assemble a day in advance and store them covered in the fridge. Bring them to room temperature before serving or warm them gently to enjoy that fresh-baked feel.

Brownies
- 3/4 cup salted butter, cubed (170 grams before browning, 140 grams after)
- 4 ounces semi-sweet chocolate, chopped
- 1/4 cup vegetable oil (56 mL)
- 3/4 cup cocoa powder (63 grams)
- 3 large eggs, at room temperature
- 1 large egg yolk, at room temperature
- 3/4 cup granulated sugar (158 grams)
- 1 and 1/2 cups powdered sugar (174 grams)
- 2 tsp vanilla extract

Topping
- Flaky sea salt (optional)
Instructions
- Prep: Preheat your oven to 350℉ (175℃). Spray a 9×13 inch metal pan with nonstick spray and line it with parchment paper for easy removal and slicing later.
- Make the Chocolate Chip Cookie Dough: Melt 14.5 tbsp salted butter in a large mixing bowl. Whisk in the dark brown sugar and granulated sugar until combined. Add the eggs and vanilla extract and whisk until smooth, about 30-45 seconds. Stir in the all-purpose flour, baking soda, baking powder, and salt until just combined, then fold in the chocolate chips. Divide the dough into two equal halves (about 640 grams each). Press half the dough into the prepared pan, then carefully lift out that piece of parchment paper and replace it with a fresh piece. Set aside this cookie dough layer, leaving the other half in the bowl for later.
- Brow the Butter: Place the cubed salted butter for the brownies in a medium saucepan over medium heat. Stir occasionally as the butter melts. Once melted, reduce heat to medium-low and continue cooking, stirring frequently. The butter will foam and bubble and then turn a deep golden brown with a nutty, caramel aroma. This process takes about 3-6 minutes. Remove from heat once browned.
- Make the Brownie Batter: Stir the chopped semi-sweet chocolate into the browned butter until fully melted and smooth. Whisk in the vegetable oil and cocoa powder and set aside to cool slightly. In a large bowl, whisk the eggs, egg yolk, and granulated sugar for 1-2 minutes until the sugar is fully dissolved and the mixture is smooth to the touch. Add the powdered sugar, vanilla extract, and salt, whisking to combine. When the chocolate mixture has cooled but is still warm, whisk it into the egg and sugar mixture. Fold in the flour and optional espresso powder, then fold in the semi-sweet chocolate chips.
- Assemble: Spread slightly more than half of the brownie batter evenly in the bottom of the lined 9×13 pan. Carefully lay the prepared sheet of cookie dough on top, removing the extra piece of parchment paper beneath it. Spread the remaining brownie batter evenly over the cookie dough layer. Form large, thick discs with the remaining cookie dough dough kept in the bowl and place them on top of the brownie batter layer. Press extra chocolate chips into any exposed cookie dough spots, if desired.
- Bake: Bake the brookies for 38 to 44 minutes until the cookies are golden and the brownies have a shiny, set top. A toothpick inserted into a brownie area should come out with moist crumbs but no wet batter. Avoid overbaking.
- Cool and Serve: Let the brookies cool in the pan on a wire rack for 1 to 2 hours before slicing. Optionally, sprinkle the top with flaky sea salt for a salty-sweet finish. Store leftovers in an airtight container at room temperature for 3-4 days. Reheat slices in the microwave for a warm treat.
