Upgrade your classic brownies with brown butter! These beauties are super dense, fudgy, and decadent with that famous crackly top that we know and love.


  • 10 tablespoons (150g) unsalted butter, cut into 10 slices
  • 6 ounces (170g) chopped semi-sweet chocolate, good quality *see notes
  • 3/4 cup (150g) granulated sugar
  • 1/2 cup (100g) packed brown sugar, light or dark
  • 3 large eggs, at room temperature
  • 1 teaspoon pure vanilla extract
  • 1/2 cup (40g) unsweetened cocoa powder
  • 1/2 cup (60g) all-purpose flour, spoon and leveled
  • 1/4 teaspoon salt
  • 1 cup (170g) semi-sweet chocolate chips or chunks (optional)
  • flaky sea salt (optional - for topping)


  1. Preheat your oven to 350°F. Grease and line an 8x8 inch baking pan with parchment paper, leaving a bit of paper hanging over the sides to make it easier to pull the baked brownies out. Set aside.
  2. In a medium saucepot, add butter slices and place onto a stove burner set to medium heat. Heat, stirring frequently, until the butter melts and turns a light golden brown color. It will foam quite a bit, but it should settle down once the butter is ready to take off the heat. This will take about 5 to 8 minutes from start to finish.
  3. Working relatively quickly so the butter doesn't continue browning from the residual heat in the pan, whisk in chopped chocolate until melted and smooth. Set aside to cool slightly.
  4. In a large bowl, combine both sugars and eggs. Using an electric mixer fitted with the whip attachment or a whisk by hand (it is a workout though!) whisk together sugars and eggs until the sugar is dissolved. This will take around 5 to 7 minutes. To test if it's ready, rub some of the mixture between your fingers. It shouldn't feel grainy.
  5. Add your vanilla, cocoa, and slightly cooled brown butter mixture to the egg mix. Whisk to combine.
  6. Add flour, salt, and chocolate chips to the wet ingredients. Mix together until just combined. Take care not to overmix!
  7. Pour your batter into the prepared baking pan. Bake in the center of your preheated oven for 25 to 30 minutes, or until the top is no longer shiny and a skewer inserted into the center comes out with moist crumbs.
  8. Cool completely in the pan. Once cool, use the overhanging parchment paper to pull the brownies out and cut into 16 slices. (Optional) Sprinkle some flaky sea salt on top before serving!


* Good quality chocolate makes all the difference in flavor and texture! If you can swing it, try to use Baker's or couverture chocolate, which is specifically made for melting / baking.
