For the Sponge Cake:

  • 4 large eggs
  • 1/2 cup (100g) granulated sugar
  • 1 cup (120g) all-purpose flour, sifted
  • 1/4 cup (60ml) milk
  • 2 tablespoons (30g) unsalted butter, melted
  • 1 teaspoon vanilla extract

For the Diplomat Cream:

  • 1 cup (240ml) milk
  • 1/2 vanilla bean, split and seeds scraped
  • 3 large egg yolks
  • 1/4 cup (50g) granulated sugar
  • 2 tablespoons (16g) cornstarch
  • 1 tablespoon (14g) unsalted butter
  • 1/2 cup (120ml) heavy cream, whipped to soft peaks
  • 2 gelatin sheets (or 5g gelatin powder)

For the Assembly:

  • 1 pound (450g) fresh strawberries, hulled and halved
  • 1/4 cup (60ml) simple syrup (equal parts sugar and water, boiled until sugar dissolves)
  • Optional: powdered sugar for dusting, mint leaves for garnish


  1. Sponge Cake: Preheat oven to 350°F (180°C). Whisk eggs and sugar until light and fluffy. Fold in flour, then milk, butter, and vanilla. Pour into a lined 9-inch (23cm) round cake pan and bake for 20-25 minutes. Cool.
  2. Diplomat Cream: Heat milk with vanilla bean and seeds. Whisk egg yolks, sugar, and cornstarch. Gradually add hot milk to yolk mixture, return to heat, and whisk until thickened. Remove from heat, add butter, and cool slightly. Dissolve gelatin in cold water, then add to pastry cream. Fold in whipped cream when mixture is cool.
  3. Assembly: Cut sponge cake in half horizontally. Brush each layer with simple syrup. Arrange strawberry halves around the edge of a cake ring or springform pan. Spread a layer of diplomat cream, add a layer of sponge cake, more cream, and another layer of cake. Chill for at least 4 hours.
  4. Remove the ring, decorate with strawberries, dust with powdered sugar, and garnish with mint if desired.

Q1: Can I substitute the diplomat cream with another type of cream? A1: While diplomat cream is traditional for a Fraisier, you can use mousseline cream or even a simple whipped cream if you prefer. Each will offer a different texture and flavor profile to the cake.

Q2: What if I don’t have a candy thermometer for making the diplomat cream? A2: If you don’t have a candy thermometer, you can test if the sugar has dissolved in the egg whites by rubbing a little of the mixture between your fingers. It should feel smooth, not grainy.

Q3: How can I ensure my sponge cake layers are even? A3: Use a serrated knife to carefully slice the sponge cake into even layers. You can also use cake levelers, which are specifically designed for this purpose.

Q4: Can I make the Fraisier a day ahead? A4: Yes, the Fraisier benefits from being made a day ahead as it allows the flavors to meld together and the cream to set properly. Just be sure to store it in the refrigerator and add any final decorations before serving.

Q5: What’s the best way to decorate the Fraisier? A5: Traditional decorations include a layer of marzipan or almond paste on top, but you can also use whipped cream, fresh strawberries, and edible flowers for a more modern look. Gold pearls or a zest of lime can add an elegant touch.
