In a microwave-safe bowl, heat 1/2 cup butterscotch chips at 70% power for 2-3 minutes or until melted, stirring occasionally. Cut a small hole in the corner of a pastry or plastic bag; insert a #4 round tip. Fill with melted chips. Pipe "mom" eight times onto a waxed paper-lined baking sheet. Refrigerate until set, about 10 minutes.
In a large bowl, stir the coffee and remaining butterscotch chips until chips are melted. Stir in half-and-half and sugar. Serve in mugs with whipped cream and "mom" garnishes.
