Instructions
Preheat the oven to 400°F (200°C). Unroll the first sheet of puff pastry onto a baking sheet, prick it thoroughly with a fork, cover it with a second sheet of parchment paper and weigh it down with a second baking sheet.
Bake until golden, about 15 to 20 minutes. Do the same with the second sheet, but sprinkle it with 1 tablespoon of sugar before baking (it caramelizes in the oven and makes a crisp top layer). Let both sheets cool.
Cover the gelatin with 100 ml (1/3 cup) cold water in a small bowl and let it bloom. In a heavy-bottomed pot, whisk the yolks, sugar, flour and a little of the milk until smooth.
Add the remaining milk and cook over medium-low heat, stirring constantly, until you have a thick pudding. Remove from the heat and stir in the vanilla.
Warm the bloomed gelatin (in the microwave or over a water bath) until liquid, without boiling, and stir it into the hot custard.
Cover the custard with plastic wrap touching the surface (to prevent a skin) and let it cool to room temperature.
Whip the cream to stiff peaks. Gently fold it into the cooled custard by hand or on the lowest speed, until you have a fluffy diplomat cream.
Place the bottom sheet (the one without sugar) in a pan or on a board and spread all the cream over it, smoothing the top. Cover with the caramelized sheet (shiny side up) and press down lightly.
Refrigerate until set, ideally overnight. Slice with a serrated knife and dust with powdered sugar.
- Use a sharp serrated (bread) knife and cut with a gentle sawing motion, without pressing down, so the cake does not squash and the filling does not squeeze out.
- For extra flavor, simmer a whole vanilla bean in the milk instead of using extract; the black seeds look beautiful in the cream.
- Variations: layer fresh raspberries or sliced strawberries over the cream; or skip the sugar on top and glaze the top sheet with dark chocolate ganache.
