Instructions

Step 1

Step 1: Whip the egg whites with 70 grams (2.45 ounces) of sugar until stiff peaks form. Ensure the bowl and whisk are clean and dry for best results.

Step 2

Step 2: In a separate bowl, whip the yolks with the remaining 30 grams (1.06 ounces) of sugar and vanilla extract until pale. The mixture should almost double in volume.

Step 3

Step 3: Gently fold the whipped whites into the yolk mixture using a spatula. Do this carefully to maintain the airy texture.

Step 4

Step 4: Gradually add the sifted flour, followed by the fresh blueberries, mixing gently each time. Ensure the batter is homogeneous, but avoid over-mixing.

Step 5

Step 5: Transfer the dough into a 20-22cm (7.87-8.66 inch) mold lined with parchment paper. Even out the top for uniform baking.

Step 6

Step 6: Bake in an oven preheated to 302°F (150°C) for 1 hour. Do not open the oven door during baking.

Step 7

Step 7: For the cream, whip the mascarpone, whipping cream, sugar, and vanilla extract until fluffy. Ensure the cream holds its shape.

Step 8

Step 8: For the soaking, combine the lemon juice, orange juice, and sugar until the sugar dissolves. Use fresh juices for better flavor.

Step 9

Step 9: Divide the sponge biscuit into 3 layers. Soak each layer with the juice mixture about 10 minutes before assembling. Ensure even soaking for consistent moisture.

Step 10

Step 10: Assemble the cake by layering with cream and refrigerate for several hours or overnight. Overnight chilling allows flavors to meld.

Step 11

Step 11: Decorate the cake to your taste. Fresh fruits or edible flowers make for a beautiful presentation.

Variations

Want to make this sensational cake gluten-free or vegan? We've got you covered! 🥳

Gluten-Free: Swap the regular flour for your favorite gluten-free flour blend, ensuring it contains xanthan gum to mimic the texture of wheat flour.

Vegan: Replace the eggs with a flaxseed mixture (1 tbsp flaxseed meal + 2.5 tbsp water per egg), use vegan sugar, and opt for dairy-free mascarpone and whipping cream alternatives readily available in stores.

Note: These variations may alter the texture slightly, but the flavor will remain delicious! 🌱
