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