In a heavy saucepan, combine the sugar, coffee, corn syrup, and
      cinnamon.  Bring to a boil over medium heat, stirring occasionally. 
      Cook until a candy thermometer reads 230-240 degrees (soft-ball
      stage).  Remove from heat and stir in vanilla.  Add peanuts and
      stir quickly.  Pour onto two buttered baking sheets.  Quickly
      separate into small clumps with two forks.  Cool completely. 
      Store in an airtight container.  Yield:  6 cups.
