Heat the milk and sugar together in a small saucepan and whisk, then break the chocolate into it.
I don’t like cream, but go ahead and top your thick hot chocolate with whipped cream and marshmallows if you’re in the mood for a bigger treat than usual!
The hot chocolate might still seem quite thin when you pour it into your cups, but bear in mind it will thicken up more as it cools.
Pop the leftovers in the fridge to make a delicious thick chocolate pudding - just for you!
This would also make a delicious chocolate sauce for ice cream or cake.
