Ingredients
Scale
Choux Pastry
- 1 cup (125g) all-purpose flour
- 1/2 cup (115g) unsalted butter
- 1 cup (240ml) water
- 4 large eggs (cold)
Custard Filling
- 1 cup (200g) granulated sugar
- 4 large egg yolks
- 1/4 cup (30g) cornstarch
- 2 cups (480ml) milk (warmed)
- 2 tbsp unsalted butter
- 1 tsp vanilla extract
Finishing
- Powdered sugar (for dusting)
Instructions
- Prepare the Choux Pastry: Heat water and butter together in a saucepan until the butter melts completely. Remove from heat, add sifted flour all at once, and stir vigorously over low heat until the dough forms a ball and pulls away from the pan. Let it cool slightly before beating in cold eggs one at a time until the mixture is smooth and shiny. This dough will be used to pipe or spoon two rectangular layers.
- Bake the Pastry Layers: Divide the dough evenly between two baking trays lined with parchment paper. Spread or pipe into rectangles, leaving space for rising. Bake in a preheated oven at 200°C (about 390°F) for 25-30 minutes until puffed, golden, and crisp. Do not open the oven early to prevent deflation. The layers should be hollow and airy inside.
- Make the Custard Filling: While the pastry cools, whisk together sugar, cornstarch, and egg yolks in a saucepan. Gradually add warmed milk and cook over medium heat, stirring constantly until thickened to a pudding-like consistency. Remove from heat and stir in butter and vanilla extract for a smooth, silky finish. Allow the custard to cool completely.
- Assemble the Cake: Place one choux pastry layer onto a serving plate. Spread the cooled custard evenly over it, then top gently with the second pastry layer. Press lightly to secure the layers, then chill the cake in the refrigerator for at least one hour to allow the filling to set and flavors to meld.
- Final Touches: Just before serving, dust the top layer generously with powdered sugar to create a snowy, mountainous effect. Slice carefully with a serrated knife to maintain the layers intact. Enjoy the perfect balance of crispy crust and creamy filling.
Notes
- Use cold eggs for the dough to incorporate air and keep the choux light and fluffy.
- Stir the custard continuously over medium heat to prevent lumps and burning.
- Allow pastry layers to cool completely before assembling to avoid a soggy cake.
- Chill the assembled cake before slicing for clean, firm slices.
- Maintain steady oven temperature and avoid opening the door during baking to keep pastry puffed.
