Boil prunes for 10 minutes in enough water to cover, drain, cool and chill.
Cut prunes into small pieces. Slice bananas. If you are using large marshmallows, cut them into 8 pieces. Whip cream until stiff, add prunes, bananas, marshmallows, lemon extract, and fold in.
Serve in footed glasses with a maraschino cherry on top. Fluff can be stored in the refrigerator for up to two days.
