  3. Bring back to a very slow boil over medium low heat and cook, stirring continuously for another 15-20 minutes until the mixture darkens slightly and thickens.
  4. Remove from heat and pour into the prepared shortbread base. Chill for 2 hours or more until thoroughly cooled before adding the chocolate topping.

Chocolate Topping

  1. Melt together the chocolate chips and butter in a double boiler.
  2. Spread evenly over the cooled caramel and let stand until the chocolate sets before cutting into bars or squares.
