Napoleon in a glass

1. Introduction

Traditional Napoleon cakes can be difficult to slice without crushing the delicate pastry layers. This glass-version simplifies the process by using broken pastry pieces, ensuring every spoonful has the perfect ratio of velvety custard to flaky crust. It is finished with a light dusting of powdered sugar to mimic the classic decorated top.

2. Ingredients

• The Pastry:

  • 1 sheet frozen puff pastry, thawed.

  • 1 tbsp granulated sugar (for sprinkling).

• The Pastry Cream:

  • 2 cups whole milk.

  • 1/2 cup granulated sugar.

  • 1/4 cup cornstarch.

  • 4 large egg yolks.

  • 2 tbsp unsalted butter.

  • 1 tsp vanilla bean paste or extract.

• The Finish:

  • 1/4 cup powdered sugar (for dusting).

3. Instructions

1. Bake the Pastry: Preheat your oven to 400°F (200°C). Place the puff pastry sheet on a baking sheet, prick it all over with a fork, and sprinkle with sugar. Bake for 15–20 minutes until deep golden and crisp. Let it cool completely, then crumble into bite-sized pieces.

2. Make the Cream: In a saucepan, bring the milk to a simmer. In a separate bowl, whisk the egg yolks, sugar, and cornstarch. Slowly temper the hot milk into the yolks, then return the entire mixture to the heat. Whisk constantly until it thickens into a heavy custard.

3. Chill: Remove from heat and stir in the butter and vanilla. Transfer to a bowl, cover the surface directly with plastic wrap to prevent a skin from forming, and refrigerate until cold.

4. Assemble the Glasses:

   • Place a layer of pastry crumbles at the bottom of each glass.

   • Pipe or spoon a thick layer of vanilla pastry cream over the pastry.

   • Repeat the layers, finishing with a generous topping of golden pastry crumbles.

5. Garnish: Just before serving, dust the tops of the glasses with powdered sugar.

4. Variations

• Berry Napoleon: Add a layer of fresh sliced strawberries or raspberries between the cream and pastry layers for a fruity contrast.

• Chocolate Twist: Fold 1/2 cup of melted dark chocolate into half of the pastry cream to create a duo-tone chocolate and vanilla version.

• Salted Caramel: Drizzle salted caramel sauce over each pastry layer for added richness and depth of flavor.

5. Serving and Storage

• Service: For the best texture, assemble the glasses no more than 1–2 hours before serving to ensure the pastry remains crisp.

• Storage: The pastry cream can be made up to 2 days in advance and stored in the refrigerator.

• Pro Tip: If the pastry crumbles lose their crunch, you can quickly toast them in a dry pan for 2 minutes before assembling.
