Melt 1/2 cup (125 mL) chocolate chips in a double boiler. Meanwhile, using an electric mixer, beat the cream cheese until smooth. Add icing sugar, graham crumbs, vanilla and salt, and blend well. Mix in the melted chocolate and the remaining chocolate chips. Cool mixture in the freezer until firm, about 15 min.
Hand-roll into balls the size of large marbles. Toss balls in coconut, sprinkles or cookie crumbs until well coated. Return to freezer and chill thoroughly, about 15 min., or until ready to serve or wrap up.
