Preheat oven to 350°F. Line two baking sheets with parchment.
Whisk flour, cocoa, baking soda, salt, ginger, cinnamon, cloves, nutmeg, and espresso powder.
Cream softened butter with brown sugar and granulated sugar until light and fluffy.
Beat in molasses, vanilla, and egg until smooth and glossy.
Add dry ingredients in two additions. Mix just until a soft dough forms.
Fold in chocolate chips. Cover and chill 20–30 minutes to firm slightly.
Scoop 1.5-tablespoon portions. Roll balls in sanding sugar to coat.
Arrange on sheets, spacing 2 inches apart. Bake 9–11 minutes, until edges set.
Cool 5 minutes on the sheet, then transfer to a rack to finish cooling.
