Ingredients:

  • 8 oz (225 g) Dark Chocolate (70% Cacao minimum), chopped or chips
  • 1 stick (1/2 cup / 115 g) unsalted butter, cubed
  • 1 cup (200 g) granulated sugar
  • 1/2 cup (110 g) light brown sugar, packed
  • 2 large eggs, room temperature
  • 1 tsp (5 ml) vanilla extract
  • 3/4 cup (90 g) all-purpose (plain) flour
  • 1/4 cup (25 g) unsweetened cocoa powder (Dutch Process)
  • 1/2 tsp baking powder
  • 1 tsp fine sea salt
  • 1/2 cup (85 g) chocolate chips or chunks (optional mix-in)

Instructions:

  1. Combine the chopped dark chocolate and cubed unsalted butter in a heatproof bowl set over a saucepan of simmering water (bain-marie), or in a heavy saucepan over very low heat. Stir until completely smooth. Remove from heat immediately.
  2. Add both the granulated and brown sugars directly into the hot chocolate-butter mixture. Whisk vigorously for 1–2 minutes until the mixture is glossy, slightly thickened, and the sugar has largely dissolved. This step is crucial for achieving the crinkle top.
  3. Whisk the eggs into the chocolate mixture one at a time until fully incorporated. Stir in the vanilla extract. The mixture should be thick and shiny, like a proper brownie batter.
  4. In a separate medium bowl, whisk together the flour, cocoa powder, baking powder, and salt.
  5. Gently fold the dry ingredients into the wet mixture using a rubber spatula until just combined. Stop mixing as soon as no streaks of flour remain. Fold in optional chocolate chips.
  6. Cover the bowl and chill the dough in the refrigerator for at least 45 minutes, up to 1 hour. The dough must be firm enough to scoop without sticking excessively.
  7. Preheat oven to 350°F (175°C). Line baking sheets with parchment paper or silicone mats.
  8. Use a medium cookie scoop (1.5 – 2 tablespoon capacity) to portion the chilled dough, placing scoops about 2 inches (5 cm) apart on the prepared sheets.
  9. Bake for 10–12 minutes. The cookies are done when the edges are set and cracked, and the centre looks slightly puffed and still very soft; they will appear slightly underdone.
  10. Let the cookies cool completely on the baking sheet for 10–15 minutes before transferring them to a wire rack. They are very delicate when hot.
