Ingredients
For the Puff Pastry:
-
2 sheets of store-bought puff pastry (or homemade, if preferred)
-
1 tablespoon flour, for dusting
For the Vanilla Custard:
-
500 ml (2 cups) full-fat milk
-
1 vanilla bean (or 1 teaspoon pure vanilla extract)
-
4 large egg yolks
-
100 g (½ cup) granulated sugar
-
30 g (3 tablespoons) cornstarch
-
30 g (2 tablespoons) unsalted butter
-
Pinch of salt
For the Topping:
-
Icing sugar, for dusting
-
Optional: melted chocolate for drizzle
Method
1. Prepare the Puff Pastry
-
Preheat your oven to 200°C (400°F) and line a baking tray with parchment paper.
-
Lightly dust your work surface with flour and roll out each sheet of puff pastry to approximately 3 mm thickness. Trim edges to make neat rectangles of equal size.
-
Place the pastry sheets on the baking tray, prick the surface lightly with a fork to prevent excessive puffing.
-
Cover loosely with parchment and bake for 12–15 minutes, until golden brown and crisp. Remove from the oven and let cool completely on a wire rack.
Tip: For an extra-crisp layer, place another sheet of parchment on top of the pastry while baking and weigh it down with another tray.
2. Make the Vanilla Custard
-
Split the vanilla bean lengthwise and scrape the seeds into a saucepan with the milk. Heat the milk gently over medium heat until it just begins to simmer. If using vanilla extract, add it later with the butter.
-
In a separate bowl, whisk the egg yolks with sugar, cornstarch, and a pinch of salt until pale and smooth.
-
Gradually pour about half of the hot milk into the egg mixture, whisking constantly to temper the eggs and prevent curdling.
-
Pour the tempered egg mixture back into the saucepan with the remaining milk. Cook over medium heat, stirring continuously with a whisk until the custard thickens and reaches a pudding-like consistency.
-
Remove from heat and stir in butter (and vanilla extract if using). Strain the custard through a fine sieve to remove any lumps and ensure smoothness. Allow it to cool slightly.
Tip: Cover the custard with plastic wrap directly on its surface to prevent a skin from forming while it cools.3. Assemble the Vanilla Custard Slice
-
Place one puff pastry sheet on a serving tray, flat side up.
-
Spread the slightly cooled custard evenly over the pastry, ensuring it reaches the edges. Smooth the top with an offset spatula for an even layer.
-
Carefully place the second puff pastry sheet on top of the custard. Press gently to ensure it adheres.
-
Refrigerate the assembled slice for at least 2 hours (or overnight) to set, allowing the custard to firm up for clean slicing.
4. Finishing Touches
-
Just before serving, dust the top layer with icing sugar for a classic presentation.
-
Optional: drizzle melted chocolate over the top in a zigzag pattern for extra elegance.
-
Use a sharp, serrated knife to slice the custard into individual rectangles or squares. For precise cuts, warm the knife slightly under hot water and wipe dry between slices.
Serving Tip: Pair with fresh berries or a dollop of whipped cream to elevate the experience.
5. Variations and Tips
-
Flavor Twist: Add a teaspoon of orange zest or almond extract to the custard for a subtle, aromatic variation.
-
Chocolate Custard Slice: Replace 50 g of milk with melted dark chocolate to create a rich chocolate version.
-
Nutty Crunch: Sprinkle finely chopped toasted almonds or pistachios between the custard and top pastry for added texture.
-
Gluten-Free Option: Use a pre-made gluten-free puff pastry, ensuring the baking time is adjusted slightly to avoid over-browning.
