Ingredients
Scale
Choux Pastry
- 1 cup (120g) all-purpose flour
- 1/2 cup (115g) unsalted butter
- 1 cup (240ml) water
- 4 large eggs (room temperature)
- 1 tablespoon sugar
Custard Filling
- 2 cups (480ml) milk
- 1/2 cup (100g) sugar
- 1/4 cup (30g) cornstarch or all-purpose flour
- 4 large egg yolks
- 4 tablespoons (55g) unsalted butter
- 1 teaspoon vanilla extract
Optional Toppings
- Powdered sugar for dusting
- Chocolate shavings
- Fresh berries
- Crushed nuts (pistachios or almonds)
Instructions
- Prepare the Choux Pastry Dough: In a saucepan, bring water and butter to a boil until the butter melts completely. Remove from heat and quickly stir in the flour until a smooth dough forms and pulls away from the sides of the pan. Return to low heat and stir for about 1 minute to dry the dough slightly. Allow it to cool. Once cooled, add eggs one at a time, mixing thoroughly after each addition until the batter is glossy and smooth.
- Bake the Choux Layers: Preheat the oven to 200°C (390°F). Divide the dough evenly between two baking trays lined with parchment paper. Spread into rectangular or square shapes as desired. Bake for 25-30 minutes until golden brown and puffed. Remove from the oven and allow to cool completely.
- Make the Custard Filling: In a saucepan, combine sugar, milk, cornstarch (or flour), and egg yolks. Cook over medium heat, stirring constantly until the mixture thickens to a creamy custard consistency. Remove from heat and whisk in butter and vanilla extract until smooth. Cover the surface with plastic wrap to prevent a skin from forming. Chill until fully cooled.
- Assemble the Cake: Place one choux pastry sheet on a serving dish. Spread the chilled custard filling evenly on top. Place the second pastry sheet on top and press gently. Refrigerate for a few hours, preferably overnight, to let the flavors meld and for the custard to firm up.
- Serve: Dust the top with powdered sugar or cocoa powder, if desired. Slice into squares or rustic pieces and serve with optional fresh berries, whipped cream, or vanilla ice cream for an enhanced experience.
Notes
- Use room temperature eggs to ensure smooth choux dough and better rise.
- Do not open the oven door early to avoid your pastry collapsing.
- Stir the custard constantly until it reaches a pudding-like consistency to ensure proper thickening.
- Allow both pastry and custard to cool fully before assembling to prevent sogginess.
- Refrigerate assembled cake overnight for the best flavor and texture.
