Ingredients:

  • 1 cup (2 sticks) Unsalted Butter, cut into cubes
  • 4 oz Dark Chocolate (70% cocoa minimum), finely chopped
  • 1½ cups Granulated Sugar
  • ½ cup Light Brown Sugar, packed
  • 3 Large Eggs, room temperature
  • 1 tbsp Pure Vanilla Extract
  • ¾ cup All-Purpose Flour
  • ¼ cup Unsweetened Cocoa Powder (natural), sifted
  • 1 tsp Fine Sea Salt
  • ½ cup Chocolate Chips or Chopped Nuts (Optional Mix-in)

Instructions:

  1. Preheat your oven to 350°F (175°C). Line a 9x9 inch baking pan entirely with parchment paper, leaving an overhang on two sides for easy removal.
  2. In a heavy-bottomed saucepan, combine the butter and chopped dark chocolate. Melt over low heat, stirring occasionally, until smooth. Remove from heat.
  3. Immediately whisk in both the granulated and brown sugars into the chocolate mixture. Whisk vigorously for about 30–60 seconds; the heat will start dissolving the sugar granules, which is key for the top crust.
  4. Transfer the warm chocolate-sugar mixture to a large mixing bowl. Add the room-temperature eggs one at a time, whisking very vigorously after each addition until fully incorporated and the mixture thickens slightly. Add the vanilla extract with the last egg and whisk for a full minute to create the desired emulsion.
  5. In a separate small bowl, whisk together the flour, cocoa powder, and salt.
  6. Add the dry ingredients to the wet mixture. Use a rubber spatula to fold them in until just combined. Stop immediately when no streaks of dry flour remain to ensure a fudgy, not cakey, result.
  7. Gently fold in any optional chocolate chips or nuts.
  8. Pour the batter into the prepared pan, levelling the top gently. Bake for 30–35 minutes.
  9. Test for doneness: The edges should look set, but the center should still look slightly soft. A toothpick inserted into the center should come out with moist, sticky crumbs attached (not clean).
  10. Remove from the oven and allow them to cool completely (1–1.5 hours) on a wire rack before lifting out of the pan and slicing. Do not cut the brownies while warm.
