1 cup powdered sugar
1 cup butter or margarine
1/2 cup molasses
1 egg
1 Tablespoon vinegar
2 teaspoons cinnamon
1-1/2 teaspoon ground ginger
3-1/2 (approx) cups flour
1-1/2 teaspoon baking soda
1 teaspoon salt
Cream sugar and butter together until smooth. Add next 5 ingredients and mix until just blended. In a medium bowl, whisk together flour, baking soda and salt. Add to butter mixture and mix just until incorporated.
Pat dough into a ball and wrap thoroughly in plastic wrap or a plastic zipper bag. Refrigerate for at least 1 hour or up to several days.
When ready to bake, preheat oven to 375F.
Remove dough from refrigerator and cut in half. Roll each half out on a floured surface to 1/4" thickness and cut into desired shapes. Scraps can be gathered and rolled out again.
Sprinkle with colored sugar and add cinnamon decorations, if desired.
Bake in preheated oven for 7 to 8 minutes.
