Mix the first 5 ingredients together in a small bowl. Cream together the butter, sugar, egg and vanilla. Mix until it looks like pastry dough. Add water if necessary. Shape into 1 inch balls and place 3 inches apart on an ungreased cookie sheet. Flatten with a moistened fork to 1/8 inch thick.
Bake at 375ºF for 6 to 10 min or until slightly browned. Makes about 3 dozen cookies.
