Ingredients:

  • 1 cup (227g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 2 large eggs
  • 1 teaspoon (5ml) vanilla extract
  • 1/2 cup (42g) unsweetened cocoa powder
  • 2 cups (250g) all-purpose flour
  • 2 teaspoons (10g) baking powder
  • 1/4 teaspoon (1.5g) salt
  • 2 oz (57g) unsweetened chocolate, melted and slightly cooled
  • 1/2 cup (60g) granulated sugar (for rolling)
  • 1 cup (120g) powdered sugar (for rolling)

Instructions:

  1. In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
  2. Beat in the eggs one at a time, then stir in the vanilla extract and melted chocolate.
  3. In a separate bowl, whisk together the cocoa powder, flour, baking powder, and salt.
  4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix. The dough will be thick and sticky.
  5. Cover the bowl with plastic wrap and chill in the refrigerator for at least 2 hours, or preferably overnight. This is crucial for preventing the cookies from spreading too much.
  6. Preheat oven to 350°F (175°C). Line cookie sheets with parchment paper or silicone baking mats.
  7. In a small bowl, place granulated sugar. In another bowl, place powdered sugar. Using a spoon or small cookie scoop, form dough into 1-inch balls. First, roll in granulated sugar, then roll generously in powdered sugar, ensuring they are completely coated.
  8. Place the sugar-coated dough balls onto the prepared cookie sheets, leaving about 2 inches between each cookie.
  9. Bake for 10-12 minutes, or until the edges are set and the tops are cracked. Do not overbake; they should still be slightly soft in the center.
  10. Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
