Ingredients

  • 173 grams unsalted brown butter (about 15 tablespoons (210 g) unsalted butter before browning)
  • 1 cup (85 g) unsweetened dark (Dutch process) cocoa powder
  • 1 1/2 cups (255 g) dark chocolate (finely chopped)
  • 4 large eggs (room temperature)
  • 1 cup (200 g) granulated sugar
  • 3/4 cup (165 g) light brown sugar (packed)
  • 1 1/2 tablespoons (19 g) real vanilla extract
  • 1 teaspoon sea salt
  • 1 cup (135 g) all-purpose flour (how to measure flour)
  • 2 teaspoons (10 g) sea salt flakes (optional)

Instructions

For the Brown Butter

  • Preheat the oven to 350°F (177°C). Grease an 9 x 13–inch (23 x 33–cm) baking dish and line with parchment paper, letting the excess fall over the sides. (see note below regarding pan size)
  • Place 15 tablespoons (210 g) butter in a small sauce pan and melt over medium heat. Once melted, crank up the heat to medium high. Stand by, continuously stirring and watching. Small golden bits will start to settle on the bottom of the pan. Once this happens, take it off the heat and pour into a medium, heat-safe bowl (be sure to scrape all of the brown bits too!).

For the Brownie

  • In a large mixing bowl (that's heat safe) add the cocoa powder and pour the hot browned butter over the top, whisking to thoroughly combined. Add the chopped chocolate, stirring to combine. Set aside, stirring frequently until smooth and all of the chocolate is melted.
  • In the bowl of a stand mixer fitted with the whisk attachment, add the eggs, sugar, brown sugar, vanilla and salt and whisk on medium-high for about 5 to 7 minutes or until thick and light in color. Add in the melted chocolate-butter mixture and run the mixer for 30 seconds on low to combine. Take the bowl out of the mixer and use a rubber spatula to fold in the flour until just combined (make sure there aren't any flour pockets). Pour the batter into the prepared baking dish.
  • Bake on the middle of the preheated oven for 25 to 27 minutes. When done, the tops will be shiny and if you test with a toothpick moist crumbs will cling to it. Note: the crinkly top won't show up until you pull them out of the pan and cut them. Let them cool in the pan for several hours and if you want super, uber fudgy brownies shove them in the fridge for several hours when cooling. Sprinkle with the sea salt flakes, if using.
  • When it’s time to cut the brownies, use a very sharp knife and use a wet paper towel to clean off the knife in between cuts. Enjoy!

Notes

To Whip Up the Eggs & Sugar

For best results, use either a stand mixer or a hand mixer to really whip up the eggs and sugar mixture.

How to Cut Brownies

The first rule for cutting perfect brownies is the hardest: let the brownies cool completely!
If you want super clean cuts, chill your brownies for several hours before cutting them.
Lastly, use a very sharp knife and clean + dry the knife in between cuts.
I tend to be impatient so my brownies are never perfectly cut, such is life.
NOTE: I cut the brownies into 12 brownies for the photos (which is quite large); but you can cut them into up to 20 brownies if you need to serve more people. 

Storing Homemade Brownies

Brownies can be stored at room temperature in an airtight container for several days.

Brownie Pan Sizes

For this homemade brownie recipe, you can also use a 9×9 (23×23-cm) square baking pan. Bake the brownies in the center of the oven for about 35 minutes (depending on how fudgy you want your brownies to be).
I did find in testing this recipe that the larger 9×13 (23×33-cm) yielded brownies that had a bit more crinkle.

To Serve

These brownies are unreal on their own with a glass of cold milk or, turned into more of a dessert with vanilla ice cream and drizzled in brown sugar caramel
