Line trays or baking sheets with waxed paper, set aside. In a medium heavy saucepan (or double boiler), heat and stir 12 oz. semisweet chocolate pieces over low heat until melted. Remove from heat and stir in the cream cheese until well combined (mixture will thicken). Stir in chopped cookies. Use a small scoop to drop mounds of mixture on the prepared trays. Cover and freeze for 15 minutes or until firm.

In a small heavy saucepan (or double boiler), combine the 2 1/4 cups milk chocolate pieces; heat and stir over low heat until melted and smooth. Remove from heat.
