For a special effect, use a decorative tip to pipe the mousse into each glass. All you need is a large star tip and piping bag.
Microwave hazelnut spread, uncovered, on HIGH for 25 seconds (be sure to completely remove foil wrap). Fold hazelnut spread and whipped topping together in a large bowl, leaving some chocolate streaks. Spoon mousse into a zip-top plastic freezer bag (do not seal). Snip 1 corner of bag to make a hole. Pipe mousse into parfait glasses. Serve with biscotti; or crush biscotti, and lightly sprinkle over each serving to provide the crunch.
