Ingredients

For the Pastry Cream:

• 500 ml (2 cups + 2 tbsp) whole milk

• 1 tsp pure vanilla extract or the seeds of 1 vanilla bean

• 4 large egg yolks

• 100 g (1/2 cup) granulated sugar

• 40 g (1/3 cup) cornstarch

• 30 g (2 tbsp) unsalted butter, cubed and softened

• A pinch of salt

For the Crisp Puff Pastry Layers:

• 1 sheet (about 230g) frozen all-butter puff pastry, thawed

• 2 tbsp granulated sugar

For Assembly & Garnish:

• 250 ml (1 cup) heavy whipping cream, cold

• 2 tbsp powdered sugar, plus more for dusting

• 6 clear dessert glasses or wide champagne coupes

Equipment

• Medium saucepan

• Whisk

• Heatproof bowl

• Fine-mesh sieve

• Plastic wrap

• Baking sheet

• Parchment paper

• Rolling pin

• Electric hand mixer or stand mixer

• Piping bag (optional, but recommended for neat layers)

Step-by-Step Instructions

Step 1: Prepare the Pastry Cream (Can be done a day ahead)

1. Heat the Milk: In a medium saucepan, combine the milk and vanilla (or vanilla bean seeds and pod). Heat over medium until it just begins to simmer. Remove from heat, cover, and let the vanilla infuse for 10 minutes. If using a bean pod, remove it.

2. Whisk Egg Mixture: In a separate bowl, vigorously whisk the egg yolks, 100g of sugar, cornstarch, and salt until the mixture is pale, thick, and smooth.

3. Temper the Eggs: Slowly pour about 1/3 of the hot milk into the egg mixture, whisking constantly. This gradually raises the temperature of the eggs without scrambling them.

4. Cook to Thick: Pour the tempered egg mixture back into the saucepan with the remaining milk. Cook over medium heat, whisking constantly and scraping the bottom and corners, until the mixture comes to a low boil and thickens dramatically (about 1-2 minutes). It should be very thick and pudding-like.

5. Finish & Chill: Remove from heat and immediately whisk in the softened butter until fully incorporated and glossy. Press the cream through a fine-mesh sieve into a clean bowl to ensure it’s perfectly smooth. Place plastic wrap directly on the surface to prevent a skin from forming. Refrigerate for at least 4 hours, or overnight.

Step 2: Bake the Crisp Puff Pastry

1. Prep & Cut: Preheat your oven to 200°C (400°F). Line a baking sheet with parchment paper. On a lightly floured surface, roll the thawed puff pastry sheet into a rectangle roughly 10×12 inches (25x30cm). Prick the surface all over with a fork to prevent excessive puffing.

2. Sugar & Bake: Sprinkle the surface evenly with the 2 tablespoons of granulated sugar. Place another piece of parchment on top and a second baking sheet to weigh it down (this creates beautifully flat, crisp layers). Bake for 15-18 minutes, or until deep golden brown and crisp.

3. Cool & Crumble: Remove the top baking sheet and parchment. Let the pastry cool completely on the tray. Once cool, break it into rough, bite-sized pieces and shards. Set aside.

Step 3: Whip the Cream & Assemble

1. Lighten the Cream: In a large bowl, whip the cold heavy cream and 2 tbsp of powdered sugar until stiff peaks form.

2. Fold & Combine: Take the chilled pastry cream from the fridge and whisk it briefly to loosen it. Gently fold in about 1/3 of the whipped cream until fully combined. This lightens the dense pastry cream. Then, fold in the remaining whipped cream until you have a smooth, airy diplomat cream. Be gentle to maintain volume.

3. The Grand Assembly: Place half of the pastry crumbles into a zip-top bag and crush lightly with a rolling pin to create a “crumb” layer.

   • Layer 1: Place a spoonful of the crushed pastry crumbs in the bottom of each glass.

   • Layer 2: Pipe or spoon a generous layer of the diplomat cream over the crumbs.

   • Layer 3: Add a layer of the larger pastry shards, pressing them gently into the cream.

   • Repeat: Add another layer of diplomat cream, then finish with a final artistic arrangement of a few large pastry shards on top.

4. Chill & Serve: Refrigerate the assembled desserts for at least 30 minutes before serving. Just before serving, dust the top dramatically with a snowfall of powdered sugar.

Chef’s Notes & Success Tips

• Make-Ahead Magic: Both the pastry cream and the baked puff pastry can be made 1-2 days in advance. Store the pastry cream covered in the fridge and the baked pastry in an airtight container at room temperature. Assemble up to 4 hours before serving.

• Texture is Key: The contrast between the silky cream and the shatteringly crisp pastry is everything. Assemble no more than 4 hours ahead to ensure the pastry retains its perfect crunch.

• Flavor Twists: Add a tablespoon of bourbon or rum to the pastry cream after cooking. For a chocolate version, sift 2 tbsp of cocoa powder into the egg yolk mixture.

• No Piping Bag? Use a sturdy plastic bag with a corner snipped off, or simply spoon the cream carefully for a more rustic look.
