01 - Whisk together flour, baking soda, baking powder, ginger, cinnamon, cloves, nutmeg, and salt in a medium bowl. Set aside for later use.
02 - Beat softened butter and brown sugar together on medium speed until light and creamy, approximately 2 minutes.
03 - Add egg, molasses, and vanilla extract to the butter mixture. Mix until thoroughly combined.
04 - Gradually incorporate dry ingredients into wet mixture on low speed until a thick, uniform dough forms.
05 - Divide dough into two equal portions. Flatten each into a disk, wrap in plastic, and refrigerate for minimum 1 hour or up to overnight.
06 - Preheat oven to 350°F. Line baking sheets with parchment paper.
07 - On lightly floured surface, roll one dough portion to 1/4 inch thickness. Cut into shapes with cookie cutters and place 1 inch apart on prepared sheets.
08 - Bake for 8-10 minutes until edges begin turning golden. Cool on pan for 2 minutes, then transfer to wire rack to cool completely.
09 - Stir powdered sugar with 2-3 tbsp milk or water until smooth but not runny. Adjust liquid for desired consistency.
10 - Once cookies are fully cooled, decorate with icing and sprinkles. Allow icing to set completely before serving or storing.
