Sponge Biscuit
Strawberry Marshmallow
Custard
Instructions
Step 1
- Separate the egg whites and yolks: Make sure no yolks get into the whites, as this can prevent them from whipping properly.
- Whip the yolks with half of the sugar (62.5 grams or 2.20 ounces) and all the vanilla sugar until pale and fluffy: This usually takes about 5-7 minutes with an electric mixer on high speed.
- Place the egg whites in a clean, grease-free bowl and whip until stiff peaks form: Gradually add the remaining sugar (62.5 grams or 2.20 ounces) and whip for another 3-4 minutes.
- Gently fold one-third of the whipped egg whites into the yolk mixture: Use a spatula and a gentle lifting and folding motion to keep the mixture light and airy.
- Sift the flour and carefully fold it into the mixture: Do this in parts to avoid lumps.
- Fold in the remaining egg whites until well combined: Be careful not to deflate the mixture.
- Pour the batter into a 16 cm (6.3 inch) mold, filling it no more than two-thirds full: This allows space for the cake to rise.
- Bake at 350°F (175°C) for 30-35 minutes until golden and a skewer inserted into the center comes out clean.: Let it cool in the mold for a few minutes before turning it out onto a wire rack to cool completely.
Step 2
- Combine the strawberries and 100 grams (3.55 ounces) of sugar in a saucepan: Cook on medium heat for 2-3 minutes until the sugar dissolves.
- Blend the mixture until smooth and strain through a sieve: You should get around 150-160 grams (5.30 ounces) of puree.
- Soak the gelatin in cold water: Follow the package instructions for soaking time.
- In a separate saucepan, combine half the puree with half the glucose syrup (70 grams or 2.50 ounces) and all the sugar (130 grams or 4.60 ounces): Bring to a boil until sugar dissolves.
- Add the gelatin to the hot mixture and stir until dissolved: Ensure the gelatin is fully melted.
- Whip the remaining puree with the glucose syrup for 1-2 minutes: Use a high-speed mixer for best results.
- Gradually pour in the hot syrup while whipping at high speed: Continue to whip until the mixture lightens and becomes very dense.
- Pipe the mixture onto parchment paper in desired shapes and sprinkle generously with powdered sugar: Allow to set for 4-6 hours.
Step 3
- Combine heavy cream, cream cheese, and powdered sugar in a mixing bowl: Make sure the cream cheese is at room temperature for easier mixing.
- Whip until smooth and fluffy: Use an electric mixer for best results.
Step 4
- Soak the sponge cakes in lukewarm milk with vanilla sugar: Use enough milk to make the cakes moist but not soggy.
- Place the first cake layer on your serving plate and cover it with a layer of custard: Use a pastry bag for more even spreading.
- Add fresh berries in the middle and cover with a thin layer of custard: This adds a fresh fruit flavor to the cake.
- Place the marshmallow layer on top and cover with a thin layer of custard: Ensure the layers are even.
- Repeat with the remaining layers: Continue until all layers are assembled.
- Apply an even layer of custard all over the cake to catch crumbs and prepare it for the final coating: Chill the cake to set the crumb coat before applying the final layer.
Step 5
- Apply the final layer of custard evenly: Use a spatula for a smooth finish.
Enjoy your delicious homemade pastry!

Variations
Gluten-Free and Vegan Variations:
🍃 Gluten-Free: Swap out the regular flour for a gluten-free blend, ensuring your cake layers are just as fluffy and delicious. You'll also want to make sure your vanilla sugar is gluten-free, as some brands may contain traces.
🌱 Vegan: Replace the eggs with flaxseed or chia seed substitutes (1 tablespoon of seeds + 3 tablespoons of water per egg). Use agar-agar instead of gelatin for the marshmallow layer, and opt for vegan cream cheese and dairy-free cream for the custard. 😊
Faq
- Why did my sponge cake not rise properly?
Make sure your egg whites are whipped to stiff peaks and gently fold the flour to maintain the airiness of the mixture.
- Can I use a hand mixer instead of a stand mixer?
Yes, a hand mixer works fine but might take a bit longer, and you'll need to ensure you hold it steadily to achieve the desired consistency.
- How can I prevent the marshmallow layer from being too sticky?
Generously coat your parchment paper with powdered sugar before spreading the marshmallow mixture.
- Is it possible to make the custard without electric mixers?
Yes, but it will require more manual effort. Use a sturdy whisk and ensure all ingredients are at room temperature for easier mixing.
- How do I get smooth, even layers for my cake?
Using a pastry bag helps in spreading the custard evenly. Also, a rotating cake stand can make the process more manageable.
- What's the best way to store the cake?
Keep it refrigerated in an airtight container. The cake is best consumed within 2-3 days for ultimate freshness.
