Ingredients:
For the Puff Pastry:
- 1 package of puff pastry sheets (thawed if frozen)
- 1/4 cup powdered sugar (for dusting)
For the Pastry Cream:
- 2 cups whole milk
- 1 vanilla bean (or 2 teaspoons vanilla extract)
- 1/2 cup granulated sugar
- 5 large egg yolks
- 1/4 cup cornstarch
- 2 tablespoons unsalted butter
For the Icing:
- 1 cup powdered sugar
- 2-3 tablespoons milk
- 1 teaspoon vanilla extract
For the Chocolate Decoration:
- 1/4 cup semi-sweet chocolate chips
- 1 teaspoon vegetable oil
Instructions:
- Prepare the Puff Pastry:
- Preheat your oven to 400°F (200°C).
- Roll out the puff pastry sheets on a lightly floured surface to smooth them out.
- Place the pastry sheets on a baking sheet lined with parchment paper.
- Prick the pastry all over with a fork to prevent it from puffing up too much.
- Place another sheet of parchment paper on top and another baking sheet to weigh it down.
- Bake for 15-20 minutes, or until golden brown.
- Remove the top baking sheet and parchment paper, and let the pastry cool completely.
- Once cooled, trim the edges to make straight lines and cut each sheet into equal rectangles.
- Make the Pastry Cream:
- In a medium saucepan, heat the milk and vanilla bean (or vanilla extract) over medium heat until just boiling. Remove from heat and let it sit for 10 minutes to infuse.
- In a mixing bowl, whisk together the sugar and egg yolks until pale and thick.
- Add the cornstarch and whisk until smooth.
- Gradually pour the hot milk mixture into the egg mixture, whisking constantly to prevent curdling.
- Pour the mixture back into the saucepan and cook over medium heat, stirring constantly, until it thickens and comes to a boil.
- Remove from heat and stir in the butter until melted and smooth.
- Transfer the pastry cream to a bowl, cover with plastic wrap (pressing it directly onto the surface), and refrigerate until cold.
- Assemble the Mille-Feuille:
- Place one layer of puff pastry on a serving platter.
- Spread a generous layer of pastry cream over the pastry.
- Repeat with another layer of puff pastry and pastry cream, finishing with a layer of puff pastry on top.
- Prepare the Icing:
- In a bowl, mix the powdered sugar, milk, and vanilla extract until smooth and thick.
- Pour the icing over the top layer of puff pastry, spreading it evenly.
- Add the Chocolate Decoration:
- Melt the chocolate chips with the vegetable oil in a microwave-safe bowl, stirring every 30 seconds until smooth.
- Transfer the melted chocolate to a piping bag or a small plastic bag with a tiny corner cut off.
- Pipe lines of chocolate across the icing.
- Use a toothpick to drag through the chocolate lines to create a feathered effect.
- Chill and Serve:
- Refrigerate the assembled Mille-Feuille for at least 1 hour to set.
- Slice carefully with a sharp knife and serve chilled.
Enjoy this elegant and delectable Mille-Feuille as a delightful dessert!
