Someone requested recipes for unusual Christmas cookies. This is a little different and is very good.
In a large pot, combine dates, butter, sugar, and egg. Bring to a boil, stirring constantly over medium heat. Cook for 10 minutes, continuing to stir. Add vanilla and rice krispies, mixing well. Allow to cool until you can handle it. Roll into small balls, then roll in cocunut (or powdered sugar if desired).
