1. In a saucepan, beat the cream, cocoa and sugar together until all the lumps have been removed.
2. Add the butter and bring to a boil over medium to medium heat.
3. Stir continuously, simmer. Keep stirring until you get a thick sauce. The sauce is thick enough when the drops slowly fall from your spoon.
4. Let cool and pour into a glass jar and put in the fridge to cool. After cooling, your chocolate sauce is ready!
