Directions to follow
- Preheat your oven to 400°F (200°C).
- Lay the puff pastry sheets on parchment-lined baking trays, pricking them all over with a fork to keep them from puffing excessively.
- Bake each sheet for 12-15 minutes, until they’re golden and crisp. Remove from the oven and let cool completely.
- Heat the milk in a large saucepan until it’s just below boiling, then take it off the heat.
- In a mixing bowl, whisk together the sugar, egg yolks, cornstarch, flour, and salt until the mixture is smooth.
- Gradually pour the hot milk into the egg mixture, whisking constantly to temper the eggs.
- Return the mixture to the saucepan and cook over medium heat, stirring constantly until the custard thickens and comes to a soft boil.
- Remove from heat and stir in the vanilla extract and butter until the mixture is silky smooth.
- Pour the custard onto one sheet of the baked puff pastry, spreading it evenly.
- Place the second sheet of puff pastry on top and press down gently.
- Chill the custard slice in the refrigerator for at least 2 hours or until fully set.
- Finally, dust the top with powdered sugar before slicing into squares to serve.
Best ways to enjoy it
This classic custard slice can be enjoyed in many delightful ways. Serve it chilled for a refreshing dessert on a warm day, or warm it slightly for a comforting treat. A sprinkle of fresh berries or a dollop of whipped cream elevates it further, adding a burst of color and flavor. Pairing it with a rich coffee or even a light herbal tea can create an enjoyable dining experience.
Keeping leftovers fresh
To properly store your custard slice, wrap it tightly in plastic wrap or place it in an airtight container in the refrigerator. It will stay fresh for up to 3 days. If you see it lingering beyond that, it’s best to check for any signs of spoilage. While I don’t recommend freezing it, you can freeze the custard layer separately. When ready to serve, simply thaw in the fridge and stack it back onto the baked pastry.
Pro chef tips
- Ensure you fully temper the eggs when combining them with hot milk. This prevents curdling and results in a smooth custard.
- Always whisk continuously while cooking the custard to avoid clumping.
- Let the custard cool slightly before pouring it onto the pastry to maintain a nice texture.
