Ingredients:

  • 1 cup (225 g) Unsalted Butter, cubed
  • 8 oz (225 g) Good Quality Dark Chocolate (60%+ cocoa solids), chopped
  • 1 ½ cups (300 g) Granulated Sugar
  • ½ cup (100 g) Light Brown Sugar, packed
  • 4 Large Eggs, room temperature
  • 1 Tbsp (15 ml) Vanilla Extract
  • ¾ cup (90 g) All-Purpose Flour
  • ¼ cup (25 g) Unsweetened Cocoa Powder (Dutch-processed preferred)
  • 1 tsp Fine Sea Salt
  • ½ cup (60 g) Chopped Walnuts or Pecans (Optional)

Instructions:

  1. Preheat oven to 350°F (175°C). Line a 9x9 inch (23x23 cm) baking pan with parchment paper, ensuring excess hangs over the sides to create a sling.
  2. In a heavy-bottomed saucepan over low heat, melt the butter and chopped dark chocolate together, stirring until smooth and glossy. Remove from heat immediately.
  3. Whisk the granulated sugar and brown sugar directly into the warm chocolate mixture until fully incorporated and the mixture looks slightly grainy. This step is essential for the crust.
  4. Add the room temperature eggs one at a time, whisking vigorously for 30–60 seconds after each addition until the mixture thickens slightly and becomes glossy. Stir in the vanilla extract.
  5. In a separate small bowl, whisk together the flour, cocoa powder, and salt.
  6. Add the dry ingredients to the wet ingredients. Use a rubber spatula to fold until just combined. Stop mixing immediately when no streaks of flour remain to prevent over-developing gluten.
  7. If using, gently fold in the optional nuts or chocolate chips.
  8. Pour the batter into the prepared pan, levelling the top gently. Bake for 30–35 minutes. The edges should look set, and a toothpick inserted near the centre should come out with moist, fudgy crumbs attached.
  9. Remove from the oven and allow the brownies to cool completely in the pan on a wire rack for a minimum of 60 minutes. This cooling process is crucial for structure and chewiness.
  10. Once fully cooled, use the parchment sling to lift the slab out of the pan. Wipe a large, sharp knife clean between cuts, and slice into 16 even squares.
