Ingredients

  • 12 crepes Ready-made crepes (prepared according to your favorite crepe batter recipe)
  • 500 ml Whole milk (for vanilla infusion)
  • 1 bean Black vanilla bean (Uganda) (scraped, seeds used)
  • 4 units Egg yolks (fresh, at room temperature)
  • 100 g Granulated sugar (for pastry cream) (white granulated sugar)
  • 30 g Cornstarch (sift before incorporating)
  • 30 g All-purpose flour (sift together with cornstarch)
  • 250 ml Heavy cream (35% fat) (whip to stiff peaks)
  • 30 g Brown sugar (for caramelizing the top)
  • 30 g Additional sugar (for caramel) (sprinkle before brûlée)

Instructions

  1. Vanilla infusion

    Split the vanilla bean in half, scrape the seeds and add them to cold whole milk. Gently bring the milk to a simmer (≈90°C), then remove from heat and let infuse for 1 hour.

    Time: PT1H

    Temperature: 90°C

  2. Prepare the yolk mixture

    In a bowl, whisk the egg yolks with the granulated sugar until the mixture lightens. Sift the cornstarch and flour directly into the bowl and mix until a homogeneous paste forms.

    Time: PT5M

  3. Cook the pastry cream

    Reheat the infused milk (without bringing to a boil). Gradually pour it over the egg mixture while whisking constantly. Return everything to the saucepan and cook over low heat, stirring continuously, until thickened (about 5‑7 minutes).

    Time: PT7M

    Temperature: feu doux

  4. Cool the pastry cream

    Transfer the cream to a container, cover immediately with plastic film touching the surface to prevent a skin from forming. Let cool to room temperature then refrigerate for 30 minutes.

    Time: PT30M

  5. Whip the heavy cream

    In a cold bowl, whisk the heavy cream until stiff yet supple peaks form.

    Time: PT5M

  6. Incorporate the whipped cream (diplomat cream)

    Take a portion of the cooled pastry cream, thin it slightly with a tablespoon of milk if needed, then fold in the whipped cream in two additions, lifting the mixture with a spatula until light and airy.

    Time: PT2M

  7. Assemble the crepe cake

    On a serving plate, place the first crepe, spread a generous spoonful of diplomat cream with a spatula, then cover with a second crepe. Repeat until all crepes and cream are used, finishing with a cream layer on top.

    Time: PT10M

  8. Chill

    Cover the cake with plastic film and refrigerate for at least 4 hours (ideally 6 hours) so the crepes soak and the cream firms up.

    Time: PT6H

    Temperature: 4°C

  9. Caramelize the top

    Just before serving, evenly sprinkle brown sugar over the cake surface. Use a kitchen torch or the oven broiler to melt and caramelize the sugar until a golden, crackly crust forms.

    Time: PT5M

    Temperature: gril du four très chaud ou flamme du chalumeau

Chef Tips from the Video

  • Use a high‑quality vanilla bean for an intense aroma
  • Cook the pastry cream over low heat to avoid lumps
  • For a smoother result, pass the diplomat cream through a sieve before assembly

Troubleshooting

Lumps in the pastry cream

Pass the cream through a sieve before returning to the heat and cook over very low heat while whisking constantly.

Diplomat cream is too runny

Whip the heavy cream longer until stiff peaks form and ensure the pastry cream is well cooled before incorporating.

Caramel does not form a crust

Use fine‑crystal sugar (brown sugar) and apply intense heat (torch or broiler) until golden.

Freezer: Can be frozen for 1 month; thaw in the refrigerator before caramelizing
