01 - Beat softened butter and packed brown sugar in a large bowl until light and fluffy. Add molasses and egg, mixing until fully combined.
02 - Whisk together flour, ground ginger, cinnamon, cloves, nutmeg, baking soda, and salt in a separate bowl.
03 - Gradually add the dry ingredient mixture to the wet ingredients, stirring until a soft dough forms.
04 - Divide dough into two portions, flatten each into a disk, wrap in plastic, and refrigerate for at least 1 hour.
05 - Preheat oven to 350°F. Line baking sheets with parchment paper.
06 - On a lightly floured surface, roll dough to approximately 1/4 inch thickness. Cut into desired shapes using cookie cutters.
07 - Place cut cookies on prepared baking sheets, spacing them about 1 inch apart.
08 - Bake for 10 to 12 minutes or until edges are firm. Allow to cool on baking sheets for 5 minutes before transferring to wire racks to cool completely.
09 - Combine powdered sugar and meringue powder in a bowl. Gradually add warm water while beating with an electric mixer until stiff peaks form, about 4 minutes. Adjust consistency with additional water if necessary. Tint with food coloring as desired.
10 - Transfer icing to piping bags and decorate cooled cookies as preferred. Allow icing to fully set before serving or storing.
