Ingredients
For the Puff Pastry
2 sheets frozen puff pastry, thawed
Powdered sugar for dusting
For the Vanilla Custard Filling
4 cups whole milk
1 cup heavy cream
1 cup granulated sugar
1 tablespoon pure vanilla extract
6 large egg yolks
¾ cup cornstarch
3 tablespoons unsalted butter
Instructions
Step 1: Bake the Puff Pastry
Preheat your oven to 400°F (200°C).
Place the puff pastry sheets on parchment-lined baking trays. Cover each sheet with another piece of parchment paper and place a second baking tray on top to keep the pastry flat while baking.
Bake for 20–25 minutes or until golden brown and crisp. Allow the pastry to cool completely.
Trim the edges if desired for neat layers.
Step 2: Prepare the Vanilla Custard
In a large saucepan, heat the milk, cream, and half of the sugar over medium heat until steaming but not boiling.
In a separate bowl, whisk together the egg yolks, remaining sugar, and cornstarch until smooth and pale.
Slowly pour some of the warm milk mixture into the egg mixture while whisking continuously to temper the eggs. Gradually add the remaining milk mixture.
Return everything to the saucepan and cook over medium heat, whisking constantly, until the custard becomes thick and smooth.
Remove from heat and stir in the butter and vanilla extract.
Step 3: Assemble the Vanilla Slice
Place one sheet of baked puff pastry into a lined baking dish.
Pour the warm custard over the pastry and spread evenly.
Carefully place the second pastry sheet on top and gently press down.
Refrigerate for at least 4 hours, or overnight, until fully set.
Step 4: Slice and Serve
Dust generously with powdered sugar before serving.
For clean slices, use a sharp serrated knife and wipe it clean between cuts.
Serve chilled and enjoy every creamy, flaky bite.
