Preparation

1. Melt the butter and coconut oil in a saucepan over a low heat. Add the chocolate in pieces and melt together while stirring constantly. Stir in the powdered sugar and vanilla sugar and mix in the coconut flakes and rum well. 

Place the liquid mixture in the fridge for approx. 2 - 3 hours, stirring once or twice at the beginning.
2. As soon as the mixture is solid, use a ball cutter or teaspoon to cut out small portions, quickly shape them into small balls and roll them in the coconut flakes. 

This recipe makes about 70 - 80 rum balls.
