📝 Instructions

14 steps
1

Preheat your oven to 200°C (400°F).

2

Line a baking tray with parchment paper. Place one puff pastry sheet on the tray and use a fork to prick it all over to prevent the pastry from puffing up too much. Repeat with the second sheet on a separate tray.

3

Bake the pastry sheets for 12-15 minutes until golden brown and crisp. Allow them to cool completely.

4

In a medium saucepan, combine milk, butter, and vanilla extract. Heat gently until the butter melts and the mixture is hot but not boiling. Remove from heat and set aside.

5

In a bowl, whisk together the caster sugar and cornflour. Add the egg yolks and whisk until well combined and smooth.

6

Gradually pour the hot milk mixture into the egg yolk mixture, whisking constantly to avoid curdling.

7

Return the mixture to the saucepan. Cook over medium heat, whisking constantly until the mixture thickens to a custard consistency. This should take about 5-7 minutes.

8

Once thickened, remove from heat and allow the custard to cool slightly, stirring occasionally to prevent a skin from forming.

9

Place one baked pastry sheet in the base of a square baking dish. Spread the cooled custard evenly over the pastry.

10

Top with the second pastry sheet, pressing down gently to set.

11

For the icing, sift the icing sugar into a bowl. Add the boiling water and lemon juice and stir until smooth.

12

Pour the icing over the top pastry layer and use a spatula to spread it evenly.

13

Chill the custard slice in the refrigerator for at least 2 hours to set.

14

Once set, use a sharp knife to cut into squares or slices before serving.
