Kitchen Tools You’ll Need
- Baking sheet
- Mixing bowl
- Whisk
- Saucepan
- Sharp knife
- Pastry brush
Ingredients
- 2 cups (480ml) regular milk (3.5% fat, for creaminess)
- 3.5 oz. (100g) heavy cream (for richness)
- 1 vanilla bean pod, scraped out (for aromatic flavor)
- 2.1 oz. (60g) cornstarch (for thickening)
- 1/4 cup (50g) sugar (for sweetness)
- 1 medium egg (for binding)
- 1 medium egg yolk (for richness)
- 2 rolls of fresh puff pastry dough (9.7 oz./275g each, chilled for flakiness)
- 2 tbsp. sugar (for sprinkling)
- 1/8 tsp. vanilla powder (for additional flavor)
- 2-3 tbsp. raspberry jam without seeds (optional, for fruity contrast)
- Some whisked egg yolk for brushing (for shine)

How to Make Puff Pastry with Vanilla Custard Filling
Step 1. In a medium saucepan, combine the regular milk, heavy cream, and scraped vanilla bean pod. Warm these ingredients over medium heat while stirring gently. It’s essential to watch for small bubbles forming around the edges of the mixture. Once you see this, remove it from the heat, ensuring the mixture is hot but not boiling, allowing the vanilla flavor to infuse.
Step 2. In a mixing bowl, whisk together the cornstarch and sugar. Gradually add in the hot milk and cream mixture, whisking continuously to avoid any lumps. This ensures that the cornstarch dissolves correctly and blends smoothly, creating a well-combined mixture that starts to thicken.
Step 3. Place the mixture back into the saucepan over medium heat. Continue to cook while stirring constantly until it thickens and starts to bubble gently. You’ll know it’s ready when it coats the back of a spoon, creating a custard-like consistency. This step is crucial as it builds the custard’s rich texture and flavor.
Step 4. Remove the saucepan from the heat and stir in the egg and egg yolk until fully incorporated. This addition will enrich the custard further, giving it a lovely creaminess. Make sure the eggs are fully mixed in and the mixture is smooth to avoid any egg ‘scrambling.’
Step 5. Transfer the thickened custard into a bowl. You may want to cover it with plastic wrap, pressing it directly against the surface to avoid a skin forming as it cools. Set it aside at room temperature until it has cooled and thickened further, ideally for about 30 minutes.
Step 6. Preheat your oven at this point if desired, and prepare the puff pastry. Unroll the chilled puff pastry dough onto a lightly floured surface. Cut the dough into squares or rectangles, depending on your preferred shapes. Keep the pieces as uniform as possible for even baking.
Step 7. On half of each pastry piece, dollop a spoonful of the cooled vanilla custard, ensuring it is toward the center and leaving some space around the edges to seal. If you’re including raspberry jam, you can add a small amount on top of the custard for a fruity flair.
Step 8. Gently fold the other half of the dough over the filling to create a pocket. Pinch the edges to seal tightly, ensuring the custard doesn’t leak out during baking. You may use a fork to crimp the edges for an appealing design and added security.
Step 9. Place the filled pastries on a baking sheet lined with parchment paper. For extra flavor and a beautiful golden finish, brush the tops with the whisked egg yolk, then sprinkle with sugar and a hint of vanilla powder for added sweetness and an elegant touch.
Step 10. Bake the puff pastries in the preheated oven until they are puffed and golden brown. You’ll know they are done when they have a beautifully even color and a crispy texture. Allow them to rest for a few minutes before serving, as they can be quite hot inside.

Pro Tips for Best Results
- Ensure the puff pastry is chilled before you work with it; this helps it puff up beautifully during baking.
- For a more intense vanilla flavor, consider adding a dash of vanilla extract to the custard.
- If using a savory filling instead of sweet, reduce the sugar for a balanced flavor.
- Watch the pastries closely during the last few minutes of baking to prevent over-browning.
- Let the custard cool completely before filling the pastries to avoid making the dough soggy.
- Store any leftovers in an airtight container to keep the pastry as crisp as possible.
Common Mistakes to Avoid
- Using warm pastry dough: If the puff pastry dough is warm, it will not rise properly in the oven. Always keep it chilled until you’re ready to use it for the best texture.
- Overfilling the pastries: Adding too much filling can lead to leaks during baking. Use just enough custard to fill without spilling out, leaving room for the dough to rise.
- Not sealing the edges properly: Skipping the sealing step may cause the pastries to open up while baking. Ensure they are tightly sealed to keep the filling contained.
- Under-cooking the custard: If the custard isn’t thickened enough when removed from heat, it may remain runny after baking. Be sure it coats the back of a spoon before moving on to the next step.
- Not baking long enough: Removing pastries too early can lead to sogginess; ensure they are golden brown and puffed for the ideal texture.
- Ignoring oven temperature variations: Oven temperatures can vary significantly. Keep an eye on the pastries, adjusting baking times as needed to achieve a consistent golden color.
Variations & Substitutions
For a different flavor profile, you might try adding a dash of almond extract to the custard. Alternatively, swapping the raspberry jam for a lemon curd can provide a refreshing twist. You could also sprinkle toasted nuts on the top before baking for added texture and crunch.
Storage & Reheating
These pastries are best enjoyed fresh but can be stored at room temperature for up to one day. If you have leftovers, place them in the refrigerator for up to three days to maintain freshness. While freezing is possible, it may alter the texture. To reheat, place them in an oven for a few minutes at a low temperature to regain crispness.
