Whisk the egg whites and sweetener in a bowl until the mixture becomes stiff but not dry.
In another bowl, combine the fromage frais and vanilla essence.
Carefully fold the egg white mixture into the fromage frais mixture using a metal spoon.
Pour the mixture into a freezer-proof container and freeze it for about 2-3 hours or until it becomes firm.
Remove the ice cream from the freezer 15 minutes before serving. You can serve it with fresh slices of pineapple, kiwi, and papaya to make it more delicious.
Enjoy your creamy vanilla ice cream without feeling guilty!
