Puff Pastry with Custard and Whipped Cream

Prepare the Puff Pastry:
- - Preheat the oven to 200°C (392°F).
  - In a saucepan, bring the water, butter, and a pinch of salt to a boil.
- - Add the flour all at once, stirring vigorously until the mixture forms a smooth dough.
  - Remove from heat and allow to cool slightly. Add the eggs one at a time, beating well after each addition until the dough is smooth and glossy.
  - Pipe or spoon the dough onto a baking sheet lined with parchment paper.
- Bake at 200°C (392°F) for 10 minutes, then reduce the temperature to 180°C (356°F) and bake for another 20 minutes. Finally, lower the temperature to 160°C (320°F) and bake for 10 more minutes.
Make the Custard Cream:
- - In a saucepan, whisk together the egg yolks, sugar, and flour until smooth.
- - Gradually add the milk while whisking constantly.
  - Place the saucepan over medium heat and cook, stirring constantly, until the mixture thickens.
  - Remove from heat and let cool.
Prepare the Whipped Cream:
- - In a chilled bowl, whip the heavy cream with sugar until soft peaks form.
  - Gently fold in the custard cream into the whipped cream until fully combined.

Assemble the Pastries:
- - Once the puff pastries have cooled, slice them in half horizontally.
  - Fill each pastry with the custard cream mixture.
- Dust the top with powdered sugar if desired.

- Ensure the dough cools slightly before adding the eggs to avoid scrambling.
- If you prefer a more stable filling, chill the custard cream before folding it into the whipped cream.

- This dessert provides a source of protein from the eggs and a satisfying dose of calcium from the milk and cream.
- While indulgent, it can be enjoyed as part of a balanced diet.

Store the filled pastries in an airtight container in the refrigerator for up to 2 days.
