For an even richer flavor, consider using dark brown sugar for the candied pumpkin. If you don't have a kitchen torch, you can broil the parfaits for a few seconds to caramelize the sugar, but watch carefully to prevent burning. The parfaits can be assembled ahead of time and stored in the refrigerator for up to 24 hours before torching. Garnish with a sprinkle of chopped nuts or a drizzle of caramel sauce for an extra touch of indulgence.
