Beat the softened butter and brown sugar in a large bowl for 1-2 minutes, until smooth and slightly lighter. Scrape down the bowl.
02 -
Mix in the molasses, egg, and vanilla until fully combined. The mixture may look glossy and loose, which is normal.
03 -
Whisk the flour, baking soda, salt, ginger, cinnamon, cloves, nutmeg, and allspice in a separate bowl. Add to the wet mixture and mix on low just until no dry flour remains.
04 -
Divide the dough into 2 discs, wrap tightly, and refrigerate for at least 2 hours or up to 3 days. The dough should be firm enough to roll cleanly.
05 -
Heat the oven to 350°F (175°C). Line baking sheets with parchment. Roll one disc at a time on a lightly floured surface to 1/4 inch thick, then cut with gingerbread man cutters.
06 -
Transfer shapes to the baking sheets, spacing them about 1 inch apart. Bake for 8-10 minutes, until the edges look set and the centers are puffed but still soft.
07 -
Let the cookies cool on the baking sheet for 5 minutes, then move them to a wire rack. Cool fully before icing.
08 -
Whisk powdered sugar, milk or water, corn syrup, vanilla, and salt until smooth and pipeable. Add tiny splashes of liquid to thin or more powdered sugar to thicken. Decorate the cooled cookies and let the icing set.
