Mix butter, sugar, egg, molasses and water together in a large bowl. Stir dry ingredients together in a medium bowl and combine with wet ingredients. It will feel like a wet dough. Chill dough for at least 15 minutes. Preheat oven to 400 degrees. Drop by teaspoonfuls on a light greased cookie sheet. Bake 8 minutes or until hardly no imprint remains when lightly touched. While slightly warm frost with maple flavored icing.
