01 - In a medium bowl, whisk together the flour, baking soda, baking powder, ground ginger, cinnamon, cloves, nutmeg, and salt until evenly mixed.
02 - In a large bowl, use an electric mixer to cream the softened butter and brown sugar until the mixture is light and fluffy, approximately 2 minutes.
03 - Beat in the egg, then stir in molasses and vanilla extract until the mixture is homogeneous.
04 - Gradually add the dry ingredient mixture to the wet ingredients, mixing until just combined to form the dough.
05 - Divide the dough in half, shape each portion into a disk, wrap in plastic, and chill in the refrigerator for at least 1 hour or up to overnight.
06 - Preheat oven to 350°F (175°C) and line baking sheets with parchment paper.
07 - On a lightly floured surface, roll out one dough disk to a uniform thickness of 1/4 inch (6 mm).
08 - Use a gingerbread man cookie cutter to cut shapes from the rolled dough, spacing cookies about 1 inch apart on the prepared baking sheets.
09 - Bake for 8 to 10 minutes until edges are firm and centers are set. Remove from oven and allow cookies to cool on the sheet for 2 minutes before transferring to a wire rack to cool completely.
10 - Once cooled, decorate with royal or colored icing and add mini chocolate chips, sprinkles, or candies as desired.
