01 - Whisk together flour, ground ginger, cinnamon, cloves, nutmeg, baking soda, and salt in a large bowl.
02 - Beat unsalted butter and dark brown sugar with an electric mixer until light and fluffy, about 2 to 3 minutes.
03 - Add the egg, molasses, and vanilla extract to the butter mixture and beat until well combined.
04 - Gradually blend the dry ingredients into the wet mixture until a soft dough forms.
05 - Divide dough into two halves, flatten each into disks, wrap in plastic wrap, and refrigerate for at least 45 minutes.
06 - Preheat oven to 350°F. Line baking sheets with parchment paper.
07 - Roll chilled dough on a lightly floured surface to a thickness of ¼ inch. Cut into shapes with cookie cutters.
08 - Place cut shapes on prepared baking sheets, spacing approximately 1 inch apart.
09 - If making ornaments, use a straw to cut a small hole near the top of each cookie for hanging.
10 - Bake cookies for 10 to 12 minutes until edges are firm. Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
11 - Once cooled, decorate with royal icing and desired embellishments.
