Granulated sugar (optional, for caramelizing)

Directions

Preheat the oven to 400°F (200°C).
Roll out the puff pastry and cut into rectangles (about 2×4 inches).
Place the pastry rectangles on a baking sheet lined with parchment paper.
Brush with egg wash and optionally sprinkle with a little granulated sugar.
Place another layer of parchment paper and a second baking sheet on top to keep the pastry flat while baking.
Bake for 12–15 minutes or until golden and crisp. Cool completely.
Prepare the pastry cream and chill it if not already cold.
Assemble by layering one piece of puff pastry with a spoonful of pastry cream, a few raspberries, then another layer of pastry and repeat once more.
Top the final layer with a light dusting of powdered sugar.
Serve immediately or chill briefly before serving.

Servings and timing

This recipe yields approximately 6 to 8 mille-feuille cookies. Preparation time is about 25 minutes, plus 15 minutes baking time. Allow additional time if preparing homemade pastry cream (about 30 minutes).

Variations

Swap raspberries for strawberries, blueberries, or blackberries depending on the season.
Add a drizzle of chocolate or raspberry coulis over the top for extra flair.
Flavor the pastry cream with a hint of lemon zest or vanilla bean.
Use whipped mascarpone or cream cheese filling for a tangy twist.
Add a thin layer of raspberry jam between the cream and pastry for more fruitiness.

Storage/Reheating

Store assembled cookies in the refrigerator for up to 1 day. For best results, assemble just before serving to maintain the crispness of the pastry. The puff pastry can be baked ahead and stored in an airtight container at room temperature for up to 2 days. Do not reheat once assembled.
