Ingredients

  • 12 tablespoons (6 ounces) unsalted butter, melted
  • 1/2 cup (3 1/2 ounces) packed light brown sugar
  • 1 cup (7 ounces) granulated sugar, divided
  • 1/2 teaspoon salt
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1/3 cup molasses
  • 2 cups (10 ounces) all-purpose flour
  • 6 tablespoons cocoa
  • 2 teaspoons baking soda

Method

  • Adjust oven racks to upper-middle and lower-middle positions and preheat oven to 375°F. Line two baking sheets with parchment paper.
  • In large bowl, whisk butter with brown sugar, 1/2 cup granulated sugar, and salt until combined. Whisk in egg, vanilla, and molasses.
  • In medium bowl, whisk flour with cocoa and baking soda. Whisk into wet mixture until just combined. Chill until firm, about 10 to 20 minutes. Place remaining 1/2 cup sugar in bowl.
  • Using scoop or 1/4 cup measure, portion dough into balls and roll in sugar. Space evenly on pans and gently press dough balls to about 3/4 inch thick. Bake just until puffed and beginning to crack, 7 to 8 minutes, rotating pans from top to bottom and front to back halfway through baking.
  • Immediately after removing from oven, give pans a hard tap and gently press center of each cookie to deflate (see note). Let cookies cool on pan 2 minutes, then transfer to wire rack to cool completely.
