Empty sweetened condensed milk into a bowl.

Pour the passionfruit pulp through a sieve into the condensed milk and stir to combine (set the seeds that are left in the sieve aside)

In a separate mixing bowl, whip your whip cream until stiff peaks are formed.

Fold the passion fruit sweetened condensed milk mixture into the whipped cream (do half at a time)

If desired, pour the passion fruit mousse into individual serving bowls, top with some of the passion fruit seeds.

Place in the refrigerator for 1 hour, no longer than 5 hours... and serve
