2. Shape dough into 1-in. balls; place 2 in. apart on ungreased baking sheets. Flatten to 2-in. circles with bottom of a glass dipped in sugar.
3. Bake 10-12 minutes or until firm. Remove to wire racks to cool completely.
4. In a bowl, beat filling ingredients until blended. Spread on the bottoms of half of the cookies; top with remaining cookies.
