Prepare the caramel in a non-stick frying pan by placing all the ingredients to boil together until it gets a dark copper color. When the caramel is ready pour it in a small loaf pan and carefully tip it so that the caramel coats the bottom evenly.

Beat the eggs with the sugar using a stand or hand mixer and then add the milk piping hot as well as the vanilla. Pour the mixture in the loaf pan, place it into a larger baking dish that you have filled with at least 3 fingers of water and bake in a bain-marie for 1 hour at 180°C (make sure that the baking dish doesn't run out of water).

When it is cooked set aside at room temperature until it cools and then place it in the fridge overnight before you remove it from the loaf pan.
