Ingredients
For the Dough (Pastry Layers)
- 500 g all-purpose flour
- 300 g cold unsalted butter, cubed
- 1 egg
- 200 ml cold water
- 1 tbsp lemon juice or vinegar
- Pinch of salt
For the Custard Cream
- 1 liter milk
- 4 eggs
- 200 g sugar
- 60 g cornstarch
- 1 tsp vanilla extract
- 200 g soft butter
Instructions
- Make the Dough: In a bowl, mix together the flour and salt. Add the cold cubed butter and rub it into the flour until the mixture becomes crumbly with small butter chunks remaining. In a separate bowl, whisk the egg, cold water, and lemon juice or vinegar. Combine the wet and dry ingredients just until a dough forms, taking care not to overmix. Divide the dough into 8–10 balls, cover, and chill in the refrigerator for at least 1 hour to firm up.
- Bake the Layers: Roll each dough ball out very thinly—almost to a transparent thinness. Prick each rolled sheet all over with a fork to prevent puffing. Bake the sheets on baking trays in a preheated oven at 200°C (392°F) for 5–8 minutes, or until the layers turn lightly golden and crisp. Allow the baked layers to cool completely. Reserve any scraps from rolling for later use as topping.
- Make the Custard Cream: Heat the milk in a saucepan until warm but not boiling. In a mixing bowl, whisk together the eggs, sugar, and cornstarch until smooth and homogeneous. Gradually pour the warm milk into the egg mixture while continuously whisking to temper the eggs. Return the mixture to the saucepan and cook over medium heat, stirring constantly, until it thickens into a custard. Remove from heat, stir in vanilla extract, and let the custard cool fully. Once cooled, beat in the soft butter until the cream is smooth, light, and creamy.
- Assemble the Cake: On a serving plate, layer the baked pastry sheets alternating with generous layers of custard cream. Finish with a top layer of custard cream. Crush the reserved pastry scraps finely and sprinkle evenly over the top of the cake for texture and decoration.
- Chill: Refrigerate the assembled cake for 8 to 12 hours, preferably overnight. This chilling time allows the flaky layers to soften slightly and meld with the creamy custard, resulting in a tender, luxurious dessert with a melt-in-your-mouth consistency.
Notes
- Ensure the butter used for the dough is very cold to achieve ultra-flaky layers.
- Roll pastry sheets as thinly as possible to replicate the characteristic flakiness of Napoleon Cake.
- Tempering the eggs by gradually adding warm milk prevents curdling in the custard.
- Do not skip chilling the dough and the assembled cake, as it is crucial for texture development.
- Use fresh vanilla extract for the best flavor in the custard cream.
- The cake is best consumed within 2 days of assembly for optimal freshness.
