1/4 c  Unsalted butter; softened

    1/2 c  Powdered sugar; sifted

      1 ts Vanilla extract

      3    Egg whites; beaten

    1/2 c  All-purpose flour; sifted

      2 tb Unsalted butter; melted

---------------------------------TO FINISH---------------------------------
      4 oz Semisweet chocolate; chopped

    1/3 c  Finely shredded coconut

  Preheat oven to 425 F (220 C).  Grease several baking sheets with butter.
  In a medium-size bowl beat 1/4 cup butter with powdered sugar until
  creamy; beat in vanilla.  Gradually beat in egg whites.  Fold in flour,
  then 2 tablespoons melted (cooled) butter.  Drop small teaspoonfuls of
  mixture onto prepared baking sheets, spacing well apart; flatten each
  teaspoonful slightly.  Bake about 8 minutes or until lightly browned
  around edges.  Using a spatula, immediately remove cookies from baking
  sheet to a wire rack; cool.  Melt chocolate in a small bowl placed over a
  pan of hot, but not boiling water.  When cookies are cool, spread each one
  with a thin layer of melted chocolate; allow chocolate to set slightly
  then sprinkle with coconut.  Place in a cool place until chocolate sets
  completely.
