How to Make Brown Butter Brookies
Let’s embark on this delicious adventure together!
Prep: Preheat your oven to 350℉. Spray a 9×13 metal pan with nonstick spray and line with parchment paper to ensure easy removal later.
Make the Chocolate Chip Cookie Dough: In a large mixing bowl, melt the butter, and whisk in the dark brown sugar and granulated sugar until smooth. Now, add the eggs and vanilla extract, mixing until everything is beautifully combined—about 30-45 seconds is all it takes! Gradually stir in the dry ingredients, followed by the chocolate chips.
Divide & Press: Divide the cookie dough into two equal halves (about 640 grams each). Press one half into the bottom of your prepared pan, then set it aside. You’ll lift and replace the parchment paper for the next layer.
Brown the Butter: In a medium saucepan over medium heat, add the cubed butter. As it melts, keep stirring occasionally. Turn the heat to medium-low, continuing to cook and stir frequently. Watch as the butter becomes foamy and turns golden brown with a nutty, caramel aroma—this transformation takes about 3-6 minutes once melted.
Make the Brownie Batter: Once your butter is beautifully browned, stir in the semi-sweet chocolate until it’s fully melted. Mix in the vegetable oil and cocoa powder, letting it cool slightly. In another large mixing bowl, combine the eggs, egg yolk, and granulated sugar, whisking for 1-2 minutes until the sugar dissolves. Add in the powdered sugar, vanilla, and salt. Once your chocolate mixture is warm but not hot, whisk it into the egg mixture. Gently fold in the flour and espresso powder, finishing with the chocolate chips.
Assemble: Spread slightly more than half of the brownie batter into the bottom of the pan. Lay the cookie dough on top, gently removing that extra piece of parchment paper. Spread the remaining brownie batter over this. Form thick discs with the remaining cookie dough, placing them on top of the brownie layer. Press extra chocolate chips into any exposed spots for that extra chocolatey goodness.
Bake: Pop the pan in the oven for 38 to 44 minutes. The cookies should be golden brown, and the brownies will have that signature shiny top. A toothpick inserted into the center should come out with moist crumbs—just perfect!
Serve & Store: Let the brookies cool in the pan on a wire rack for about 1-2 hours before slicing. If desired, sprinkle with flaky sea salt for that final touch. Store any leftovers in an airtight container at room temperature for 3-4 days, and I highly recommend warming slices for an even cozier treat!
Variations & Creative Twists
- Nutty Delight: Add chopped walnuts or pecans to the brownie batter for a nutty crunch in every bite.
- Zesty Orange: Stir in some orange zest into the cookie dough for a bright, fresh twist.
- Minty Freshness: Incorporate peppermint extract in the brownie batter for a festive splash of flavor—perfect for Holiday gatherings!
- Cheesecake Swirl: Create a simple cheesecake filling using cream cheese, sugar, and vanilla, and swirl it through the brownie batter before baking for a luxurious cheesecake brownie experience.
Chef Emma’s Helpful Tips

- Ingredient Swaps: If you’re out of eggs, unsweetened applesauce or mashed bananas can work as a substitute.
- Easier Slicing: Use a sharp knife dipped in warm water to slice the brookies for clean cuts.
- Storage Suggestions: These brookies freeze beautifully! Just wrap them tightly in plastic wrap and aluminum foil, then they will stay fresh for up to 3 months in the freezer.
