Creamy Vanilla Slice with Flaky Puff Pastry

Step 2: Making the Vanilla Custard Filling

1. In a medium saucepan, heat the milk and cream over medium heat until just about to simmer. Remove from the heat.
2. In a large mixing bowl, whisk together the egg yolks, sugar, cornstarch, and salt until pale and thick.
3. Slowly pour the hot milk mixture into the egg mixture while whisking constantly to temper the eggs.
4. Pour the combined mixture back into the saucepan and cook over medium heat, whisking continuously until it thickens into a pudding-like consistency. This usually takes about 5–7 minutes.
5. Once thickened, remove from heat and stir in the butter and vanilla extract until smooth and glossy.
6. Cover the custard surface directly with plastic wrap to prevent a skin from forming, and let it cool slightly to room temperature.

Step 3: Assembling the Vanilla Slice

1. Line a square or rectangular baking dish with parchment paper.
2. Place one sheet of baked puff pastry at the bottom of the dish.
3. Spread the warm custard filling evenly over the pastry, smoothing the top with a spatula.
4. Gently place the second sheet of puff pastry on top, pressing lightly so it adheres.
5. Refrigerate for at least 4 hours (or overnight) to allow the custard to fully set and the layers to firm up.

Step 4: Adding the Vanilla Glaze (Optional)

1. In a small bowl, mix the powdered sugar, vanilla, and milk until smooth and pourable.
2. Spread the glaze evenly over the top pastry layer.
3. For a decorative touch, you can drizzle melted chocolate in lines and use a knife to create a feathered pattern.

Step 5: Cutting and Serving

1. Once chilled and set, use a sharp serrated knife to cut the dessert into neat slices.
   Tip: Dip the knife in hot water and wipe clean between cuts for cleaner edges.
2. Dust lightly with powdered sugar before serving, if desired.
3. Serve cold and enjoy the satisfying contrast of the crisp pastry and creamy custard.

Tips for Perfect Results

• Consistency is key: The custard should be thick enough to hold its shape when sliced, not runny.
• Keep it cold: Chill thoroughly before slicing to prevent the filling from spilling out.
• Flavor twist: Add a splash of rum, almond extract, or a layer of fresh berries for a creative variation.
• Homemade touch: If you have time, make your own puff pastry for an even flakier, buttery texture.
