Preheat the oven to 375°F. Line a baking sheet with parchment paper.
In a large bowl, cream the softened butter and light brown sugar with a hand mixer until light and fluffy.
Add the egg, vanilla extract, and molasses. Mix on low until combined, then beat on medium-high until smooth.
In a separate bowl, whisk together the flour, baking soda, ground cloves, ground ginger, and ground cinnamon.
Add the dry ingredients to the wet mixture in three additions, mixing until just combined after each.
Scoop the dough into 1 ½-tablespoon balls and place them on the prepared baking sheet.
Roll each dough ball in confectioners’ sugar until fully coated, then return them to the baking sheet, spacing them about 2 inches apart. For extra chewy cookies, freeze the coated balls for 10 minutes before baking.
Bake for 8 to 10 minutes, until the edges are set and the centers still look slightly soft.
Cool on the baking sheet for a few minutes, then transfer to a wire rack to cool completely.
