2In a small bowl, mix the custard powder with a little bit of the milk to form a smooth paste.
In a saucepan, heat the remaining milk over medium heat until it begins to simmer.
Add the sugar to the milk and stir until it is completely dissolved.
Gradually add the custard paste to the simmering milk, stirring continuously to avoid lumps.
Continue to cook the mixture over low heat, stirring constantly, until it thickens to your desired consistency.
Remove the saucepan from the heat and stir in the vanilla essence.
Pour the custard into serving dishes and let it cool to room temperature.
Refrigerate the custard for at least 2 hours before serving to allow it to set properly.
