In a glass mixing bowl, combine the chocolate and butter.

Either place the chocolate and butter in a microwave and heat it until melting for about 2 - 3 minutes OR place the bowl over a small pan of boiling water and allow the chocolate and butter to melt.

Pour in the cream, followed by the sugar.

Whisk all the ingredients until completely melted, blended and smooth.

Pour on top of your dessert while warm.
