1 14oz can sweetened condensed milk
½ cup Irish Cream
36oz white chocolate chips
½ cup raw pistachios, chopped

Directions:

Line a 9x9 baking dish with nonstick foil.  Or, if you don't have nonstick foil, lightly grease.
 

In a saucepan over low heat, combine the chocolate, condensed milk and Bailey's.  Stir constantly until the chocolate is completely melted.  Remove from the heat and stir in the pistachios.
 

Pour into the pan and let cool until set.  Once set, peel off the foil and cut into one inch squares.
