01 - In a large bowl, whisk together flour, baking soda, baking powder, ginger, cinnamon, cloves, nutmeg, and salt. Set aside.
02 - In another bowl, beat softened butter and dark brown sugar with an electric mixer until light and fluffy, about 2 to 3 minutes.
03 - Beat in the egg, then blend in molasses and vanilla extract until fully combined.
04 - Gradually add the dry mixture to the wet ingredients, mixing on low speed until a cohesive dough forms.
05 - Divide dough in half, shape each half into a disk, wrap tightly in plastic wrap, and refrigerate for at least 1 hour.
06 - Preheat oven to 350°F. Line baking sheets with parchment paper.
07 - On a lightly floured surface, roll one dough disk to about 1/4 inch thickness. Cut out gingerbread men shapes and transfer them to baking sheets, spacing 1 inch apart.
08 - Bake cookies for 8 to 10 minutes until edges firm. Cool on sheets for 2 minutes before transferring to wire racks to cool completely.
09 - Once cooled, decorate with royal icing and assorted candies as desired. Allow icing to set before serving or storing.
