----------------------------------COOKIES----------------------------------
    1/4 lb Butter, sweet

  1 1/4 c  Sugar

      2 lg Egg

      1 ts Vanilla extract

    1/2 c  Cocoa, unsweetened

      2 c  Flour

    1/2 ts Salt

      1 ts Baking powder

    1/2 ts Baking soda

----------------------------------FILLING----------------------------------
      4 tb Butter, sweet

      1 ts Vanilla extract

      4 c  Sugar, confectioners'

           Whipping cream
  To make the cookies, cream the butter with the sugar in a large bowl
  until light.  Beat in eggs and vanilla; set aside.  Sift the dry
  ingredients together; stir thoroughly into the butter mixture.  Cover
  the bowl with plastic wrap and refrigerate for two or three hours.
  Preheat the oven to 375 F. and grease two cookie sheets.  Roll level
  teaspoons of the dough into balls and place 2" apart on the cookie
  sheets.  Bake for 10 to 15 minutes, until the cookies are puffed and
  the surfaces slightly dry and cracked.  Cool on wire racks.
  To make the filling, cream the butter until light.  Beat in the
  vanilla and confectioners' sugar, adding the cream and continuing to
  beat until the consistency of a creamy frosting.
  Once the cookies are completely cooled, spread about 1/2 tablespoon of
  filling on the bottom of each cookie, then top with the bottom side of
  another cookie.
  Variation:  To make half the cookies peppermint-filled, add 1/8
  teaspoon peppermint extract to *half* the filling.  Tint pink or
  green before filling the sandwiches.
