This classic mille-feuille is a delicate and elegant dessert made with layers of crisp, buttery puff pastry and smooth, creamy vanilla custard. Topped with a glossy icing and signature chocolate pattern, every bite is light, flaky, and perfectly balanced between crisp and creamy.

Ingredients
2 sheets puff pastry
2 cups milk
1/2 cup sugar
4 egg yolks
1/4 cup cornstarch
1 tsp vanilla extract
2 tbsp butter

For the icing:
1 cup powdered sugar
2–3 tbsp milk
Melted chocolate for decoration

Instructions

Start by preheating your oven to 200°C (400°F). Roll out the puff pastry sheets and place them on a baking tray. Prick with a fork and bake for 15–20 minutes until golden and crisp. Let them cool completely.

In a saucepan, heat the milk until warm but not boiling.

In a bowl, whisk egg yolks, sugar, and cornstarch until smooth. Slowly pour in the warm milk while whisking continuously.

Return the mixture to the saucepan and cook over medium heat, stirring constantly until thick and creamy.

Remove from heat, add vanilla extract and butter, then let the custard cool completely.

Cut the puff pastry into even layers. Spread a thick layer of custard between each layer, stacking neatly.

In a bowl, mix powdered sugar with milk to create a smooth icing. Spread it over the top layer.

Drizzle melted chocolate in lines and use a toothpick to create the classic pattern.

Chill in the refrigerator for at least 1 hour before slicing.

Serving

Serve chilled or slightly cool for the best texture. Perfect with coffee or tea.

Storage

Store in the fridge for up to 2 days. Best enjoyed fresh for maximum crispness.
