Coarsely chop the chocolates in a blender or food processor. Add
Mascarpone and sugar and blend. Put the mixture in a glass bowl and chill
in the refrigerator for at least 15 minutes. Spread 1 tbsp. of the
Mascarpone blend on each of the 16 slices of Panettone. Place one slice
atop another to create sandwiches. Top each with a
cherry and serve.
