Preheat oven to 350 degrees F. Grease and flour thirty-six 1-3/4-inch muffin cups; set aside. Prepare Basic Dough. Shape dough into thirty-six 1-inch balls. Press balls into the bottoms and up the sides of prepared pans; set pans aside.
For filling, in a medium mixing bowl beat cream cheese and chocolate with an electric mixer until combined. Beat in sugar, egg yolks, liqueur, milk, and vanilla until combined. Spoon a rounded teaspoon of filling into each dough-lined cup.
Bake in preheated oven about 18 minutes or until crusts are golden and the filling sets. Cool tarts in pan for 10 minutes. Remove and cool for 1 hour on a wire rack. (Centers may dip slightly as they cool.) Cover and chill for up to 24 hours. To serve, top each tart with whipped cream and chocolate shavings. If desired, garnish serving plate with fresh raspberries. Makes 36 tarts.
