Ingredients

• 50 g Butter (softened; for craquelin)
• 40 g Sugar (for craquelin)
• 50 g Cake flour (for craquelin)
• 45 g Butter (for choux)
• 108 g Water (for choux)
• 4 g Sugar (for choux)
• 1 g Salt (for choux)
• 55 g All-purpose flour (for choux)
• 2 Large eggs (for choux; about 100 g edible weight)
• 20 g Butter (for tuile glaze)
• 20 g Corn syrup (for tuile glaze)
• 20 g Powdered sugar (for tuile glaze)
• 20 g Cake flour (for tuile glaze)
• 2 Egg yolks (for custard; about 34 g)
• 30 g Sugar (for custard)
• 15 g Cornstarch (for custard)

• 1 Vanilla bean (split lengthwise and scrape out the seeds)
• 75 g Heavy cream (for whipped cream; chilled)
• 7.5 g Sugar (for whipped cream)

Steps

1. 1

   Make the craquelin. Beat the softened butter and sugar together until smooth and creamy. Mix in the cake flour just until a soft dough forms.

2. 2

   Place the craquelin dough between sheets of parchment and roll it into a thin sheet, approximately 2–3 mm thick. Chill or freeze until firm, then cut 10 rounds slightly larger than the piped choux portions.

3. 3

   Make the tuile glaze. Melt the butter, then stir in the corn syrup and powdered sugar. Add the cake flour and mix until smooth. Set aside until ready to use.

4. 4

   Make the choux. Put the butter, water, sugar, and salt in a saucepan over medium heat. Heat until the butter melts and the liquid reaches a full simmer.

5. 5

   Add the all-purpose flour to the hot liquid all at once. Stir vigorously with a wooden spoon until no dry flour remains and the mixture forms a smooth ball that pulls away from the sides of the pan.

6. 6

   Continue stirring the dough over medium-low heat for about 1–2 minutes to dry it slightly; a thin film should form on the bottom of the pan. Transfer the dough to a bowl and cool for several minutes until warm rather than hot.

7. 7

   Beat the eggs. Add them to the warm dough gradually, mixing thoroughly after each addition, until the paste is glossy and thick and falls from the spatula in a slow V-shaped ribbon. You may not need every drop if the dough reaches this consistency.

8. 8

   Pipe 10 evenly sized mounds of choux dough onto a parchment-lined baking sheet. Place one chilled craquelin round over each mound and gently press it into place. Pipe or spread a small amount of tuile glaze over the tops without flattening the dough.

9. 9

   Bake at 400°F (200°C) for 20 minutes. Do not open the oven during this initial bake, or the shells may collapse.

10. 10

    Reduce the oven temperature to 350°F (175°C) and bake for another 5–10 minutes, until the surfaces are golden brown and the shells feel crisp. Cool completely on a rack before filling.

11. 11

    Make the custard. Whisk the egg yolks, sugar, and cornstarch in a saucepan until smooth. Add the milk and the seeds scraped from the vanilla bean, along with the pod.

12. 12

    Cook the custard over medium heat, whisking constantly, until it thickens and reaches a gentle bubble. Remove the vanilla pod, transfer the custard to a bowl, cover its surface directly with plastic wrap, and chill until completely cold.

13. 13

    Whip the chilled heavy cream with the sugar until medium-stiff peaks form. Whisk the cold custard until smooth, then fold the whipped cream into it in two or three additions to make the diplomat cream.

14. 14

    Transfer the diplomat cream to a piping bag. Poke a small hole in the base or side of each cooled cream puff and pipe in the filling until the puff feels pleasantly heavy. Serve soon after filling so the shells remain crisp.

Notes

The source provides the ingredient quantities and baking temperatures/times but does not provide full method details; the preparation steps above follow standard craquelin choux and diplomat-cream technique. Chill the craquelin until firm enough to cut and handle. Store unfilled shells airtight at room temperature for up to 1 day, or re-crisp briefly in a low oven before cooling and filling. Refrigerate filled puffs and eat the same day.
