In a large mixing bowl, beat the butter and sugar together until fluffy. Add the molasses, egg and vanilla. Beat well.
In a separate bowl, sift together the flour, baking powder, baking soda, salt, ginger, cinnamon and cloves.
Stir into the wet ingredients until well-incorporated (you can do this with your hands).
Separate the dough into three pieces. Form into logs and wrap in plastic wrap. Refrigerate at least 1 hour.
When ready to bake, remove dough from oven and preheat oven to 350 degrees F.
Roll dough out to a thickness of 1/4-inch. Use cookie cutters to make gingerbread people.
Bake 8-10 minutes. Let cool and decorate.
