Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

• Puff pastry sheets

• Whole milk

• Granulated sugar

• Egg yolks

• Cornstarch

• Unsalted butter

• Vanilla extract or vanilla bean

• Powdered sugar (optional for dusting)

• Fondant or white icing (for topping)

• Dark chocolate (for decorative topping)

Directions

1. Prepare the pastry cream: In a saucepan, heat the milk until just simmering. In a bowl, whisk together egg yolks, sugar, and cornstarch until smooth. Gradually add the hot milk to the egg mixture, whisking constantly. Return to heat and cook until thickened. Remove from heat, stir in butter and vanilla. Chill thoroughly.

2. Bake the puff pastry: Roll out puff pastry sheets and prick all over with a fork to prevent excessive puffing. Bake at 400°F (200°C) until golden brown and crisp. Cool completely.

3. Assemble the Mille-Feuille: Place one layer of baked pastry on a serving tray. Spread half of the pastry cream evenly over the surface. Repeat with another pastry layer and the remaining cream. Top with the final pastry sheet.

4. Decorate the top: If using fondant, melt slightly to make it spreadable. Spread over the top layer of pastry. Melt dark chocolate and pipe fine lines across the fondant, then drag a toothpick or knife through the lines to create a feathered effect.

5. Chill before serving: Refrigerate the assembled Mille-Feuille for several hours or overnight to allow it to set properly.

6. Slice and serve: Use a sharp knife to carefully cut into squares or rectangles. Clean the knife between cuts for neat slices.

Variations

Storage/Reheating
