In a large bowl, beat cookie crumbs and cream cheese until blended. Shape dough into 1-1/2-in. balls; place 2 in. apart on a waxed paper-lined baking sheet. Flatten to 1/2-in. thickness with bottom of a glass. Freeze 30 minutes or until firm.
In a microwave, melt candy coating and shortening; stir until smooth. Working with one at a time, dip cookies in chocolate coating mixture; allow excess to drip off. Place on a waxed paper-lined baking sheet. Immediately press a kiss in center. If desired, immediately sprinkle with nonpareils. Store between layers of waxed paper in an airtight container in the refrigerator.
