Heat the milk, cream and orange zest together in a saucepan until simmering then remove from the heat and pour through a sieve into a jug to remove the orange zest. Pour the infused milk mixture back into the pan and add the chocolate, stirring until the chocolate has melted and is really smooth.
Put the pan back on the heat to warm through then add the orange liqueur. Pour into a mug and serve.
