  • 1/2 tsp cream of tartar or lemon juice
  • 1 tsp vanilla paste or vanilla extract
  • 50 ml (3+1/2 tbsp) milk (room temperature)
  • Pink food coloring (optional)
  • 90 g (3/4 cup) all-purpose flour
  • 10 g (1+1/2 tbsp) cornstarch or all-purpose flour
  • 1/2 tsp baking powder

Filling:

  • 470 ml (2 cups) whipping cream or heavy cream (chilled)
  • 6 g gelatine leaves or gelatine powder or agar agar
  • 30 ml (2 tbsp) whipping cream or heavy cream (hot)
  • 1 tsp vanilla paste or vanilla extract
  • 55 g (1/2 cup) powdered sugar
  • About 13 strawberries (washed and dried)

Directions:

Sponge Cake:

  1. Preheat the Oven:
    • Preheat the oven to 160°C (320°F).
    • Line and grease a 20x20cm (8×8 inch) cake pan.
  2. Whip Egg Whites:
    • In a large bowl, whip the egg whites with cream of tartar until foamy.
    • Gradually add 40 g of sugar and whip until stiff peaks form. Set aside.
  3. Prepare Dry Ingredients:
    • In another bowl, sift together the flour, baking powder, and cornstarch.
    • Mix to combine and set aside.
  4. Beat Egg Yolks:
    • In a medium bowl, beat the egg yolks with 40 g of sugar and vanilla until thick and pale.
    • Add the milk and pink food coloring (if using) to the yolk mixture.
    • Gradually add the flour mixture, mixing just until combined. Do not overmix.
  5. Combine Mixtures:
    • Gently fold about 1/4 of the egg white mixture into the yolk mixture to lighten it.
    • Fold the yolk mixture back into the remaining egg whites until fully combined, being careful not to deflate the batter.
  6. Bake:
    • Pour the batter into the prepared cake pan and spread evenly.
    • Bake in the preheated oven for 20 minutes or until a toothpick comes out clean.
    • Let the cake cool slightly in the pan, then unmold it onto a wire rack to cool completely.
    • If desired, remove the brown cake skin while it is still warm.
    • Once cooled, cut the cake into 2 layers.

Filling:

  1. Prepare Gelatine:
    • Soak the gelatine sheets in cold water for 5-10 minutes (if using gelatine powder, skip this step and follow the package instructions for agar agar).
  2. Whip Cream:
    • Whip 470 ml of whipping cream with vanilla until medium peaks form.
  3. Dissolve Gelatine:
    • Squeeze the soaked gelatine sheets and dissolve them in 30 ml of hot whipping cream.
    • Heat for a few seconds if needed to fully dissolve.
  4. Combine Cream and Gelatine:
    • Add the dissolved gelatine mixture and powdered sugar to the whipped cream.
    • Whip until firm medium-stiff peaks form, being careful not to overwhip.

Assemble:

  1. Layer Cake:
    • Spread a thin layer of whipped cream mixture on one layer of the cake.
  2. Add Strawberries:
    • Arrange whole strawberries on the cake in a cross pattern, where you plan to cut the cake later.
  3. Add More Cream:
    • Cover the strawberries with more whipped cream mixture, using a piping bag if desired to fill any gaps.
  4. Top Layer:
    • Place the second layer of cake on top.
  5. Refrigerate:
    • Wrap the assembled cake in plastic wrap and refrigerate for at least 90 minutes.
  6. Trim and Cut:
    • Trim the edges for a neat look.
    • Cut the cake into 4 squares, then divide each square into 2 triangles, ensuring that each slice shows a section of strawberry.
