Ingredients
- 1 cup water
- ½ cup unsalted butter
- 1 cup all-purpose flour
- 4 large eggs
- 1 pinch of salt
- 2 cups whole milk
- 1 cup granulated sugar
- 2 teaspoons vanilla extract
- 4 large egg yolks
- ¼ cup cornstarch
- ½ cup unsalted butter (softened)
- Powdered sugar for dusting (optional)
- Whipped cream or fresh fruit for garnish (optional)
Instructions
- Step 1: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
- Step 2: In a saucepan, combine water and butter. Bring to a boil over medium heat.
- Step 3: Once boiling, add flour and salt all at once. Stir vigorously until the dough forms a ball and pulls away from the pan sides. Remove from heat.
- Step 4: Let the dough cool for about 5 minutes. Add eggs one at a time, mixing well after each until smooth and glossy.
- Step 5: Divide dough in half. Spread one half evenly on the prepared baking sheet into a rectangle.
- Step 6: Bake for 25-30 minutes until golden and puffed. Repeat with the second half of dough. Let both layers cool completely.
- Step 7: For the custard, heat milk and sugar in a saucepan over medium heat until sugar dissolves.
- Step 8: In a bowl, whisk egg yolks and cornstarch until smooth. Gradually add a small amount of warm milk mixture, then pour this back into the saucepan.
- Step 9: Cook over medium heat, stirring constantly, until thickened. Remove from heat and stir in vanilla extract and softened butter until fully incorporated.
- Step 10: Transfer custard to a bowl, cover with plastic wrap pressed directly on its surface to prevent skin formation, and cool to room temperature.
- Step 11: Once layers and custard are cool, place one pastry layer on a serving plate. Spread custard evenly on top, then cover with the second layer.
- Step 12: Dust the top with powdered sugar. Optionally, garnish with whipped cream or fresh fruit before serving.
Tips & Variations
- For a richer custard, substitute half of the whole milk with heavy cream.
- Make sure to add eggs one at a time to the dough for proper consistency.
- Use a fine sieve to dust powdered sugar evenly on top for a professional finish.
- Try adding lemon zest to the custard for a fresh twist.
- Serve chilled for a refreshing dessert or at room temperature for creamier texture.
Storage
Store the assembled cake covered in the refrigerator for up to 3 days. Keep it tightly wrapped to prevent the custard from drying out. Before serving, let the cake sit at room temperature for 15-20 minutes to soften slightly. Avoid freezing as it may affect the texture of the custard and pastry.

Ingredients
For the Pastry Layers:
- 1 cup water
- ½ cup unsalted butter
- 1 cup all-purpose flour
- 4 large eggs
- 1 pinch of salt
For the Custard Filling:
- 2 cups whole milk
- 1 cup granulated sugar
- 2 teaspoons vanilla extract
- 4 large egg yolks
- ¼ cup cornstarch
- ½ cup unsalted butter, softened
For Serving (Optional):
- Powdered sugar for dusting
- Whipped cream or fresh fruit for garnish
Instructions
- Preheat the Oven: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper to prevent sticking and ensure even baking.
- Prepare the Pastry: In a saucepan, combine the water and butter. Bring the mixture to a boil over medium heat, allowing the butter to melt completely and the water to reach boiling point.
- Add Flour: Once boiling, add the flour and salt all at once. Stir vigorously with a wooden spoon until the dough forms a smooth ball and pulls away from the sides of the pan, indicating it’s properly cooked. Remove from heat immediately.
- Incorporate Eggs: Let the dough cool for about 5 minutes to prevent cooking the eggs. Add the eggs one at a time, thoroughly mixing after each addition until the dough is smooth, shiny, and elastic.
- Spread Dough: Divide the dough into two equal parts. Spread one half evenly onto the prepared baking sheet, shaping it into a rectangular layer approximately ¼ inch thick.
- Bake Pastry Layers: Bake the layer in the preheated oven for 25-30 minutes, or until golden brown and puffed. Remove from oven and allow to cool completely. Repeat the process with the remaining dough for the second layer.
- Make Custard Filling: In a saucepan, gently heat the milk and sugar over medium heat until the sugar dissolves completely, making sure not to boil. In a separate bowl, whisk the egg yolks and cornstarch until smooth and pale.
- Thicken the Custard: Slowly temper the egg yolk mixture by gradually adding a small amount of the warm milk, then pour the combined mixture back into the saucepan. Cook over medium heat, stirring constantly until the custard thickens and reaches a pudding-like consistency. Remove from heat and stir in vanilla extract and softened butter until fully incorporated.
- Cool Custard: Transfer the custard to a clean bowl. Cover it with plastic wrap pressed directly onto the surface to prevent a skin from forming. Let it cool to room temperature before assembling.
- Assemble the Cake: Place one cooled pastry layer on a serving platter. Spread the entire custard evenly over this layer. Top with the second pastry layer, pressing gently to level the cake.
- Dust and Decorate: Sprinkle the top layer with powdered sugar for an elegant finish. Optionally, garnish with whipped cream or fresh fruit to enhance presentation and flavor before serving.
Notes
- Ensure the dough cools slightly before adding eggs to prevent curdling.
- Spread the dough evenly to ensure uniform baking and puffing.
- Constant stirring while making custard prevents lumps and burning.
- Cover custard with plastic wrap directly on surface to avoid skin formation.
- The cake is best served chilled, allowing flavors to meld.
- Fresh fruit choices like berries complement the creamy custard beautifully.
