To make ears, using scissors, cut each large marshmallow crosswise into 5 slices; cut each slice in half to within 1/4-inch (6 mm) of edge. Separate to look like bunny ears; press 1 side of cut edges into pink sugar, flattening slightly. Arrange on each of the white frosting mounds and use miniature candy balls for eyes and nose and chocolate sprinkles for whiskers.
