In the large bowl of a stand mixer, beat the butter on medium-high speed for 1 minute until creamy. Add the brown sugar and beat until light and fluffy.
1 cup (227g) salted butter, 3/4 cup (150g) brown sugar
Add the molasses, egg, and vanilla and beat well, scraping the sides of the bowl.
1/3 cup dark molasses, 1 large egg, 2 teaspoons pure vanilla extract
Whisk the flour, baking soda, ginger, cinnamon, cloves, and salt together in a bowl, then add to the butter and molasses mixture on low speed, mixing until combined. Cover the dough with plastic wrap and chill for at least 1 hour, or up to 3 days.
2 1/2 cups (353g) all-purpose flour, 1 1/2 teaspoons baking soda, 1 1/2 teaspoons ground ginger, 1 teaspoon ground cinnamon, 1/4 teaspoon ground cloves, 1/2 teaspoon salt
Preheat oven to 350°F. Roll the dough into balls, about 1 1/2-inch in diameter, then roll in the extra sugar and place on a parchment-lined baking sheet.
Bake for 10-12 minutes, just until the cookies begin to crack slightly on top. Remove from oven and cool completely on wire racks. Sprinkle with additional granulated sugar for extra sparkle, if desired.
1/2 cup granulated sugar
