Classic Vanilla Slice Recipe
Introduction
The classic vanilla slice is a delightful dessert featuring layers of crisp puff pastry and smooth vanilla custard. It’s a simple yet elegant treat perfect for any occasion.

Ingredients
- Puff pastry (enough for two layers)
- Vanilla custard (prepared and chilled)
- Icing sugar (for dusting)
Instructions
- Step 1: Preheat your oven according to the puff pastry package instructions. Roll out the puff pastry and place it on a baking tray lined with parchment paper.
- Step 2: Bake the puff pastry until golden brown and crisp. Allow it to cool completely.
- Step 3: Spread the chilled vanilla custard evenly over one layer of the cooled pastry.
- Step 4: Place the second layer of puff pastry on top of the custard, pressing gently to seal.
- Step 5: Chill the assembled slice in the refrigerator for at least two hours before serving.
- Step 6: Just before serving, dust the top with icing sugar for a classic finish.
Tips & Variations
- For extra flavor, add a splash of vanilla extract to your custard before chilling.
- Try topping the slice with a thin layer of melted chocolate instead of icing sugar for a rich twist.
- Use homemade puff pastry for a fresher, flakier result if time allows.
Storage
Store the vanilla slice in an airtight container in the refrigerator for up to 3 days. Reheat is not recommended as the puff pastry will lose its crispness; instead, enjoy it chilled for the best texture and flavor.

FAQs
Can I use custard powder instead of pre-made custard?
Yes, custard powder can be used to make fresh custard, which often results in a creamier filling. Just follow the package instructions to prepare before filling the pastry.
How do I prevent the pastry from becoming soggy?
Make sure the puff pastry is fully cooled before adding the custard, and chill the assembled slice well before serving. This helps keep the layers distinct and the pastry crisp.

Ingredients
Puff Pastry
- 1 sheet of puff pastry (approximately 250g)
Vanilla Custard
- 2 cups whole milk
- 1/2 cup granulated sugar
- 1/4 cup all-purpose flour
- 4 egg yolks
- 1 tsp vanilla extract
Topping
- Icing sugar, for dusting
Instructions
- Prepare the Pastry: Preheat your oven to 200°C (390°F). Roll out the puff pastry sheet to fit your baking tray, then place it on a lined baking tray. Prick the pastry with a fork to prevent it from puffing excessively and bake for 15-20 minutes or until golden and crisp. Remove from oven and let it cool completely.
- Make the Vanilla Custard: In a saucepan, heat the milk over medium heat until just below boiling. In a mixing bowl, whisk together the sugar, flour, and egg yolks until smooth. Slowly pour the hot milk into the egg mixture, whisking constantly to temper it. Return the mixture to the saucepan and cook over low heat, stirring continuously until the custard thickens and coats the back of a spoon. Remove from heat and stir in the vanilla extract. Allow the custard to cool slightly.
- Assemble the Vanilla Slice: Once the pastry is cool, spread the vanilla custard evenly over the base layer. Place another baked pastry sheet on top if desired (optional), or leave as a single layer with custard. Chill the assembled slice in the refrigerator for at least 2 hours to set.
- Add the Finishing Touch: Before serving, dust the top generously with icing sugar for a sweet and attractive finish. Cut into rectangular slices and serve chilled.
Notes
- For an extra indulgent version, you can add a top layer of puff pastry baked and placed over the custard.
- Make sure to chill the custard completely before assembly to prevent the pastry from becoming soggy.
- Use fresh eggs and high-quality vanilla extract for the best flavor.
- Store leftovers in an airtight container in the refrigerator and consume within 2 days for optimal freshness.
