Ingredients:
For the Puff Pastry:
- 2 ½ cups all-purpose flour
- 1 ½ cups cold unsalted butter (cut into cubes)
- ½ cup ice-cold water
- 1 teaspoon salt
- 1 tablespoon white vinegar (optional, for extra flakiness)
For the Custard Filling:
- 2 ½ cups whole milk
- 1 vanilla bean or 1 tablespoon vanilla extract
- 6 large egg yolks
- ¾ cup granulated sugar
- 3 tablespoons cornstarch
- 2 tablespoons unsalted butter
- 1 teaspoon vanilla extract (if using a vanilla bean, omit)
For the Icing:
- 1 cup powdered sugar
- 2 tablespoons milk
- 1 tablespoon vanilla extract
- A few tablespoons of melted dark chocolate (optional, for decoration)
For the Decoration:
- Powdered sugar, for dusting
- Dark chocolate shavings (optional)
Instructions:
1. Make the Puff Pastry:
- Start by preparing the puff pastry. In a large bowl, combine the flour and salt.
- Add the cold, cubed butter to the flour mixture. Using your fingers or a pastry cutter, cut the butter into the flour until it resembles coarse crumbs with pea-sized bits of butter.
- Add the cold water and vinegar (if using). Mix gently until a dough begins to form. Be careful not to overwork the dough.
- Turn the dough out onto a lightly floured surface and gently knead it into a ball. Wrap the dough in plastic wrap and refrigerate for at least 1 hour to chill.
- After chilling, remove the dough from the fridge and roll it out into a long rectangle, about ¼ inch thick. Fold the dough into thirds like a letter. This is the first turn. Chill again for 30 minutes, then repeat the folding and chilling process two more times. This will give the pastry its signature flaky layers.
2. Prepare the Custard Filling:
- In a saucepan, heat the milk over medium heat. If you’re using a vanilla bean, slice it open and scrape out the seeds. Add both the seeds and the pod to the milk. Bring the milk to a simmer but not a full boil. If you’re using vanilla extract, you’ll add that later.
- In a mixing bowl, whisk together the egg yolks, sugar, and cornstarch until smooth and pale.
- Slowly pour the hot milk into the egg mixture while whisking constantly. This tempering process prevents the eggs from scrambling.
- Return the mixture to the saucepan and cook over low heat, whisking constantly, until it thickens to a custard-like consistency. Once thickened, remove the saucepan from the heat and discard the vanilla pod if used.
- Stir in the butter and vanilla extract (if using) until fully incorporated. Allow the custard to cool to room temperature. Once cooled, refrigerate for about 30 minutes to firm up.
3. Assemble the Napoleon Cake:
- Preheat your oven to 400°F (200°C). Roll out the chilled puff pastry to a rectangle that will fit your baking sheet. Cut it into three equal rectangular sections (or more, depending on the size you prefer for your layers).
- Place the puff pastry rectangles onto a parchment-lined baking sheet. Prick each rectangle with a fork to prevent the pastry from puffing too much.
- Bake the puff pastry in the preheated oven for 12-15 minutes, or until golden brown and crispy. Allow the layers to cool completely on a wire rack.
4. Layer the Cake:
- Once the pastry layers have cooled, place one layer on your serving platter.
- Spread a generous amount of custard filling on top, smoothing it out evenly.
- Add the second layer of puff pastry and repeat the process with another layer of custard.
- Place the third layer of puff pastry on top, gently pressing it down to help it set.
5. Make the Icing and Decorate:
- In a small bowl, whisk together the powdered sugar, milk, and vanilla extract to create a smooth, thick icing. If you prefer a slightly thicker icing, you can add more powdered sugar.
- Spread the icing evenly over the top layer of pastry.
- For extra flair, melt some dark chocolate and drizzle it over the icing or pipe it in decorative patterns.
6. Let the Cake Set:
- Allow the assembled Napoleon Cake to rest for at least 2 hours in the refrigerator before serving. This resting period allows the layers to set and the custard to fully firm up, making it easier to cut clean slices.
7. Serve and Enjoy:
- Before serving, dust the top of the cake with a light layer of powdered sugar. You can also sprinkle some chocolate shavings on top for added decoration.
- Slice into pieces, serve, and watch your guests enjoy this luxurious dessert!
Tips for Success:
- Puff Pastry: If making puff pastry from scratch feels overwhelming, store-bought puff pastry works just as well. Just make sure to chill it properly before baking for the best flaky results.
- Vanilla Bean: For the best custard flavor, use a fresh vanilla bean. It gives a much more aromatic and rich flavor than vanilla extract. However, vanilla extract works perfectly fine in a pinch.
- Make Ahead: This cake can be made a day in advance. In fact, it often tastes even better after sitting overnight as the flavors have time to meld together.
- Decorative Touches: For a refined look, you can pipe whipped cream or use caramelized sugar shards to garnish the cake.
