Combine all dry ingredients in a bowl, mix with a whisk and set aside.
In another bowl cream together the butter and sugar until light and fluffy. Add the eggs and molasses, combine thoroughly. Add the flour mixture into the wet mixture, till combined.
Scoop out the cookies and roll in brown sugar. Freeze or bake at this point. If baking, place on a cookie sheet and bake for 10 minutes. (I used a small scoop and it made 4-5 dozen) If frozen simply pull them out and place on cookie sheet and bake.
