Ingredients

Scale
  • For the Almond Cake (Biscuit d’amandes):
    • 200g almond powder
    • 200g sugar
    • 24g egg white
    • 2 whole eggs
    • 2 egg yolks
    • 42g cornstarch
    • 150g unsalted butter (melted and cooled)
    • 60g egg white (for meringue)
    • 12g sugar (for meringue)
  • For the Blueberry Buttercream:
    • 200g unsalted butter (softened)
    • 200g blueberry purée
    • 80g sugar
  • For Decoration:
    • 12 almonds, chopped
    • Red food coloring
    • Water (enough to mix with almonds)
    • Icing sugar (to dust)

Instructions

  1. Preheat the Oven: Preheat oven to 180°C (356°F). Line a 12×12 inch (30×30 cm) baking pan with parchment paper.
  2. Make the Cake Batter:
    1. In a bowl, mix almond powder and sugar.
    2. Add 24g egg white and mix to form a paste.
    3. Add 2 whole eggs and 2 yolks, mix until combined.
    4. Sift in cornstarch and gently fold into the mixture.
    5. Stir in melted and cooled butter.
  3. Prepare the Meringue:
    1. In a separate bowl, beat 60g egg white with 12g sugar until stiff peaks form.
    2. Fold the meringue gently into the almond mixture in two additions.
  4. Bake the Cake: Pour the batter into the pan and spread evenly. Bake for 25–30 minutes until golden and set. Let it cool fully, then cut into 3 equal rectangular layers.
  5. Make the Blueberry Buttercream: Beat the softened butter with sugar until light and fluffy. Add the blueberry purée and beat until smooth and well combined.
  6. Prepare the Colored Almonds: Mix chopped almonds with a few drops of red food coloring and a little water. Roast in the oven at 180°C for 5–7 minutes until dry and slightly toasted.
  7. Assemble the Cake:
    1. Place the first cake layer on a plate and spread with buttercream.
    2. Repeat with remaining layers.
    3. Cover the entire cake with a thin layer of buttercream (crumb coat), then chill briefly.
    4. Apply a final layer of buttercream on top and sides.
  8. Decorate: Garnish with the red-colored almonds and a dusting of icing sugar. Serve chilled or at room temperature.

Notes

Ensure the blueberry purée is thick (not watery) for stable buttercream. You can substitute raspberry purée for a variation in flavor. Store the cake in the fridge for up to 3 days.
