Preheat oven to 350°F (175°C). Line baking sheets with parchment.

Whisk flour, ginger, cinnamon, cloves, baking soda, and salt in a bowl.

Beat butter and 1 cup sugar until fluffy. Add egg and molasses; mix until combined.

Stir in dry ingredients until just combined; chill 15 minutes if the dough is soft.

Roll dough into 1-inch balls, roll in extra sugar, and place 2 inches apart on sheets.

Bake 8–10 minutes until edges set but centers remain soft. Cool on pans 5 minutes before transferring to a rack.
