Ready in just under an hour (plus chilling time), this vanilla slice is a crowd-pleaser that's as satisfying to make as it is to eat.
Preheat your oven to 200°C (400°F). Line two baking trays with parchment paper.
Place the puff pastry sheets on the prepared trays. Use a fork to gently prick the pastry all over to prevent it from puffing excessively.
Bake the pastry sheets in the preheated oven for 10-12 minutes, or until golden and crisp. Remove from the oven, allow to cool completely, and trim to the desired size to fit a square or rectangular pan.
In a medium saucepan, combine the milk, heavy cream, and half of the granulated sugar. Heat over medium heat until it just begins to simmer. Remove from the heat.
In a separate bowl, whisk together the egg yolks, cornstarch, remaining sugar, and vanilla bean paste or extract until smooth.
Gradually pour the warm milk mixture into the egg yolk mixture, whisking constantly to temper the eggs. Once combined, return the mixture to the saucepan.
Cook the custard over medium heat, whisking constantly, until it thickens and begins to gently bubble. This will take about 5-7 minutes.
Remove the custard from the heat and stir in the unsalted butter until smooth. Let the custard cool slightly, then cover with plastic wrap pressed directly onto the surface to prevent a skin from forming. Allow to cool to room temperature.
Line your pan with one baked puff pastry sheet as the base. Pour the cooled custard over the pastry, spreading it evenly.
Place the second pastry sheet on top of the custard, pressing gently to secure it. Refrigerate the slice for at least 4 hours or until fully set.
To make the glaze, mix the powdered sugar, water, and vanilla extract in a small bowl until smooth. Adjust the consistency with more water if necessary.
Spread the glaze evenly over the top of the pastry. Allow it to set for 30 minutes in the refrigerator.
Using a sharp knife, cut the slice into squares or rectangles. Wipe the knife clean between cuts for a neat finish. Serve and enjoy!
