Preheat oven to 350°F. Line 2 baking sheets with parchment paper.
In a large bowl, beat softened butter and brown sugar on medium speed until light and fluffy, about 2 minutes.
Beat in molasses, egg, and vanilla until smooth. Scrape down the bowl.
In a separate bowl, whisk together flour, baking soda, salt, ginger, cinnamon, cloves, and nutmeg.
Add dry ingredients to the wet ingredients and mix on low just until a soft dough forms. If very sticky, chill 15 minutes.
Scoop dough into 1.5-tablespoon portions, roll into balls, then roll each ball in granulated sugar to coat.
Arrange on prepared sheets, spacing about 2 inches apart.
Bake 8 to 10 minutes until edges are set and tops are crackled; centers should look slightly underbaked for soft cookies.
Cool on the sheet for 5 minutes, then transfer to a wire rack. Sprinkle with coarse sugar while warm, if using.
Notes
For extra-soft cookies, pull them as soon as the edges set and the tops crack. Dough can be made up to 2 days ahead; cover and chill, then roll and bake.
