Ingredients:

  • 1/2 cup (115g) unsalted butter, melted and slightly cooled
  • 3/4 cup (150g) granulated sugar
  • 1 large egg, room temperature
  • 1 tsp (5ml) vanilla extract
  • 1/3 cup (30g) unsweetened cocoa powder
  • 1/2 cup (65g) all-purpose flour
  • 1/4 tsp (1.5g) baking powder
  • 1/4 tsp (1.5g) salt

Instructions:

  1. Preheat your oven to 350°F (175°C) and line your baking sheet with parchment paper.
  2. In a large bowl, whisk together the melted butter and granulated sugar until the mixture is smooth and slightly pale.
  3. Beat in the egg and vanilla extract vigorously for about 1 minute to aerate the batter for a shiny top.
  4. Sift in the cocoa powder, flour, baking powder, and salt directly into the wet ingredients.
  5. Stir with a spatula or spoon until just combined; do not overmix.
  6. Scoop rounded tablespoons of dough and place them 2 inches apart on the baking sheet.
  7. Bake for 9–11 minutes until the edges are set and a thin crust has formed, but the center remains slightly soft.
  8. Allow the cookies to cool on the pan for at least 10 minutes to allow the centers to set.
