Pre-heat the oven to 375°F.
Cream the butter and sugar. Add the molasses and egg and beat well. Sift the remaining ingredients and add to the sugar mixture. Chill the dough for at least 30 minutes.
Roll the dough into small balls, then roll in additional granulated sugar. Place the cookies two inches apart on a greased baking sheet. Flatten each cookie slightly with the bottom of a glass.
Bake for 8-10 minutes.
