Preheat oven to 350° Fahrenheit and line a large cookie sheet with parchment paper.
Beat butter and brown sugar together in a large bowl with either a hand or stand mixer, until light and fluffy. Add in molasses, egg, and vanilla extract and beat again until combined.
Add in the gluten-free flour, baking soda, salt, ginger, cinnamon, nutmeg, and cloves. Mix again just until a dough forms – careful not to over-mix the cookie dough!
Scoop 2 tablespoon-sized balls of dough, roll the dough between the palm of your hands to form a smooth ball, then roll the ball in sugar before placing it on your prepared baking sheet.
Lightly press down each cookie just a little to flatten it, then bake the cookies for about 10-12 minutes. Remove the cookie from the oven and transfer to a wire cooling rack to cool completely before serving or storing.
