Preparation of Pastry

  • Preheat oven to 400°F (200°C). Line two 9-inch round pans with parchment paper.
  • In a saucepan, combine water, butter, and salt. Bring to a boil.
  • Reduce heat and add flour all at once. Stir until a dough ball forms.
  • Let dough cool for 5 minutes.
  • Add eggs one at a time, beating well after each addition until dough is smooth and glossy.
  • Divide dough between pans and spread evenly. Bake for 25–30 minutes until puffed and golden. Cool completely.

Preparation of Custard

  • Warm milk in a saucepan.
  • In another bowl, combine sugar, cornstarch, flour, and egg yolks.
  • Slowly whisk in warm milk to temper the eggs.
  • Return mixture to saucepan and cook over medium heat, whisking constantly until thick and smooth.
  • Remove from heat and add vanilla. Cool completely with plastic wrap on the surface.

Assembly

  • Beat softened butter until light and creamy, then gradually add cooled custard spoonful by spoonful until smooth.
  • Place one pastry layer on a serving plate, spread custard evenly on top, then top with the second layer.
  • Refrigerate for 2 hours. Dust generously with powdered sugar before serving.

Notes

Serve with coffee or tea. Experiment with different flavors for the custard like chocolate or lemon.
