In a medium saucepan, bring 125ml of the Flora Thickened Plant Cream and sugar to a boil. Turn off the heat, and add the chocolate to the saucepan. Let the chocolate melt in the hot Flora Thickened Plant Cream for a few minutes before whisking the ingredients together until smooth. When the chocolate is melted, whisk in the rest of the Flora Thickened Plant Cream. Carefully transfer the mixture to a bowl, cover, and refrigerate until chilled.
Once fully chilled, whip the mixture with an electric hand mixer until stiff peaks form.
Divide the mousse into 8 dessert cups and serve immediately, or store covered, in the fridge, for 2-3 days.
