Preheat oven to 350 °F (180 °C).

In large bowl, beat together sugar, butter, egg, melted chocolate and vanilla until smooth. Gradually add flour while stirring. Beat until smooth. Shape dough into 48 1-inch (2.5 cm) balls.

Place balls on cookie sheet about 2-inch (5 cm) apart. Flatten with glass bottom to form 2-inch (5 cm) circles. Dip glass bottom in sugar, to prevent sticking.

Bake for 15 minutes or until cookies are slightly shiny and golden. Remove from oven let cool for 5 minutes before removing cookies from sheet. Repeat process until all dough is used up.

Spread half the cookies with Cream Cheese Icing and top with remaining ones, pressing lightly. Dust with sugar.
