* 1 500g pack of ready made Puff pastry
* 1 cup Granulated sugar
* ¼ cup Cornflour
* 50 g Butter
* 2 large Egg yolks
* 2 teaspoons vanilla essence
* ½ cup Custard powder
* 4 cups full Cream Milk
'''Lemon icing'''
* 1 cup Icing sugar
* 1 teaspoon Butter
* 2 teaspoons Lemon juice
* Grated zest of ¼ Lemon
* ½ teaspoon water

===Method===
* Leave the pastry at room temperature for a little while before rolling
* Cut the contents of packet in half and roll out each piece into 30 cm squares
* Place each square on an un-greased baking tray and stab all over with the tines/prongs of a fork to lessen the chance of it rising too much
* Bake for about 10 minutes or until Browned
* Carefully trim each sheet to about 23 cm square and pat any risen areas back down with your hands
* Line a 23 cm square baking tray with tin-foil and allow plenty of overlap for easy removal
* Place one sheet of the pastry in the foil
* Add the Sugar, Cornflour and Custard powder to a cold saucepan, add a little Milk and combine to a paste
* Whisk in the remaining Milk and mix well
* Add the Butter, heat the pan and gently bring to the Boil, stirring often
* Reduce the heat, stir in the Vanilla essence and Simmer for 3 minutes to thicken
* Whisk the Egg yolks in a separate bowl and then whisk into the pan
* Pour the hot Custard over the first piece of Puff pastry, cover with the second sheet and pat down so it comes into contact with the custard everywhere
'''Lemon icing'''
# Beat the Lemon juice and Zest in with the Butter. It may Help to Microwave the butter for a few seconds to soften first
# Beat in the Icing sugar and add a little water if needed
# Allow the sandwich to cool then spread the icing evenly over the top
# Chill in the Refrigerator
