Salted Brown Butter Brownies Recipe for Extra-Rich Flavor

Want to take your brownies to the next level? These brown butter brownies are fudgy, chewy, and infused with the toasty, hazelnut-like flavor of browned butter.

Why This Recipe is The Best

• Brown butter. Browning the butter adds a toasted, hazelnut-like note that deepens the chocolate without overpowering it.
• Minimal flour for a dense, fudgy texture. A low flour ratio keeps the structure tight and moist so each square stays soft in the center and holds at the edges.
• Thoughtful texture. Whipping whole eggs to the ribbon stage provides lift and a shiny, crackled top while the melted butter and chocolate keep the interior gooey and rich.

These brownies take a few extra steps compared with one-bowl versions, but the payoff is a deeper flavor and superior texture. Browning the butter introduces a toasty dimension while the whole-egg mixing method produces a glossy crackle top and fudgy interior.

Ingredients & Substitutions

• All-purpose flour.
• Cocoa powder. Dutch-processed cocoa gives a rounder chocolate flavor; natural cocoa will work but tastes a bit brighter.
• Chopped chocolate. Melted bar chocolate adds depth and a fudgy structure; choose a good-quality bar with around 54–70% cacao for best results.
• Unsalted butter. This is browned for flavor control.
• Granulated and light brown sugar. The combination balances sweetness and contributes to the crackly top.
• Kosher salt.
• Eggs. Cold eggs help the batter emulsify and produce a dense, fudgy result when whipped to ribbon stage.
• Vanilla extract.

Variations

• Swirls. Add salted caramel, Nutella, or a jam and swirl with a toothpick for marbled brownies.
• Mix-ins. Fold in M&M’s, chocolate chips, peanut butter chips, chopped candy, walnuts, or pecans before baking or sprinkle on top.
• Frosting. Top with cream cheese buttercream or chocolate buttercream for an extra layer of richness.
• S’mores twist. Press a graham-cracker layer into the pan, pour batter over it, and top with mini marshmallows before baking.

Professional Tips

• Brown the butter properly. Let the milk solids turn a deep amber and smell strongly nutty — don’t stop at pale gold.
• Cool the chocolate-butter before adding to eggs. The mixture should be close to body temperature to avoid scrambling or deflating the whipped eggs.
• Use crosswise parchment. Lining the pan with two perpendicular pieces makes it easy to lift the slab out and slice cleanly.

How to Make Brown Butter Brownies

Begin by browning the butter and melting the chocolate; this mixture needs to cool before combining with whipped eggs.

Brown the butter

Step 1: Cut butter into small cubes and melt in a saucepan over medium heat. Stir as it melts and foams; when the milk solids at the bottom become golden brown and the aroma is toasty and nutty, remove from heat.

Do not walk away — butter can go from browned to burnt quickly.

Step 2: Pour the hot butter over chopped chocolate and kosher salt in a heatproof bowl, scraping the pan to include the browned bits. Let sit 2–3 minutes, then whisk until smooth.

Step 3: Set the chocolate-butter aside to cool to roughly body temperature before adding to the eggs.

Make the Brownie

Step 4: Preheat oven to 350°F conventional or 325°F convection. Line a 9×9 pan with two pieces of parchment crossed so the ends hang over all four sides.

Step 5: Whip cold eggs, vanilla, sugar, and brown sugar in a stand mixer with the whisk attachment. Start on medium, then increase to high and whip 4–6 minutes until the mixture reaches ribbon stage — pale, thick, and falling in slow ribbons.

Ribbon stage creates the glossy crackled top and contributes to lift.

Step 6: With the mixer on medium, slowly stream the cooled chocolate-butter down the side of the bowl. If the mixture feels warm, cool it before adding to avoid deflating the eggs.

Step 7: Remove the bowl from the mixer and fold in sifted cocoa powder and flour with a rubber spatula until no dry streaks remain.

Bake and Cool

Step 8: Spread batter evenly in the prepared pan with an offset spatula.

Step 9: Bake about 20 minutes (350°F conventional / 325°F convection). The brownies are done when the shiny, crackled top has reached the center and the middle is puffed; a toothpick will show moist crumbs.

Start checking around 18 minutes to avoid overbaking — they continue to set as they cool.

Step 10: Cool completely before lifting from the pan and slicing. For the cleanest cuts, chill the cooled slab 20–30 minutes and wipe the knife between slices.
