Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, cream together the butter and brown sugar until light and fluffy.
Add the egg and molasses, then beat until well combined.
In a separate bowl, whisk together flour, baking soda, ginger, cinnamon, cloves, nutmeg, and salt.
Gradually add dry ingredients to wet ingredients, mixing until a soft dough forms.
Divide dough into portions and roll into balls. Flatten slightly and place on the prepared baking sheet.
Bake for 8-10 minutes, or until edges are set but centers are soft.
Let cool on the sheet for 5 minutes, then transfer to a wire rack to cool completely.
