  1. Preheat oven to 210C / Gas 6 1/2. Using a fork, prick puff pastry all over. Place onto baking trays and bake for 10-12 (or until golden brown and cooked through). Let cool.
  2. Meanwhile, make the custard: Heat together 500ml milk and butter in a saucepan. Stir until butter is melted.
  3. In a small bowl, mix together cornflour, icing sugar, eggs and remaining milk until smooth.
  4. Remove milk from the heat and gradually whisk in egg mixture. Return to the heat.
  5. Cook over medium heat until the custard starts to thicken, then cook for a further 5 minutes, stirring constantly. Remove from heat and stir in the vanilla. Let the custard cool.
  6. Place one sheet of pastry on a tray. Spread custard all over, then place the second sheet of pastry on top. Gently press to create a sandwich. Set aside.
  7. In a bowl, sift together cocoa and icing sugar. Stir in just enough milk to make a spreadable icing.
  8. Cover the whole pastry with the icing, then chill for 2 hours or until the icing hardens.
