Fast peanut butter fudge

2 c  Sugar
      1 c  Peanut butter
      1 ts vanilla extract
      3 tb Cocoa (optional)
 
  Mix sugar, 1/2 cup water, and optional cocoa in a saucepan, and boil
  rapidly for exactly one minute.  Pour over peanut butter and vanilla
  in a bowl, and beat until thick.  Pour into buttered pan and allow to
  cool. Cut into squares.
  This recipe starts out as peanut-butter fudge, but with the addition
  of powdered cocoa, can apparently been engineered to be chocolate.
  I've not tried the cholocate variation, but the basic pb is so good
  and so easy that its certainly worth the try...
