Equipment
- Mixing Bowls

An electric stand or hand mixer will make whipping the eggs and cream much easier. Speed control is crucial for achieving the right texture.
- Spatula
A silicone spatula is perfect for folding ingredients gently and ensuring you scrape every bit from the bowl.
- parchment paper
Line your baking pan with parchment paper for easy cake removal and no sticking, making clean-up a breeze.
- Oven
A reliable oven with accurate temperature control is essential. Preheat your oven to 180°C (356°F) before starting to bake.
- Baking Pan
A 22-24 cm (8.7 to 9.5 inch) round baking pan is ideal for this recipe. Non-stick pans can be helpful, but parchment lining is a good backup.
- Skewers
Use wooden or metal skewers to check the doneness of your cake. If it comes out clean, your cake is ready!

✨Serving Suggestions✨
Once your cake is assembled and looking gorgeous, it's time to think about presenting this masterpiece. Serve it on a chic cake stand to make a statement. You can dust the top with a light coating of cocoa powder or icing sugar for extra flair.
Pair a slice with a dollop of freshly whipped cream 🧁, or better yet, a scoop of vanilla ice cream 🍨. The combination of warm cake and cold ice cream is a hit every time. If you're going the coffee route, a fragrant espresso ☕️ is a fantastic companion to highlight the cake's rich flavors.
Feeling extra fancy? Add some seasonal berries around the cake for a pop of color and a touch of freshness. Strawberries 🍓, raspberries, or even a few mint leaves 🌿 can elevate the dessert to another level. Share your creation with friends or savor it alone—this cake makes every moment special!
Variations
Gluten-Free Variation
Swap out the all-purpose flour with an equal amount of gluten-free flour blend. Ensure that all other ingredients, such as baking powder, are certified gluten-free.
Vegan Variation
Replace the eggs with a mixture of 2 tablespoons flaxseed meal and 6 tablespoons of water—let it set for 5 minutes. Use dairy-free butter, mascarpone, and condensed milk such as coconut-based alternatives.
Don’t worry, these changes won’t compromise the flavor. Your cake will still be irresistible! 😋
Faq
- Can I use a hand mixer instead of a stand mixer?

- How long can the assembled cake be stored?
The cake can be stored in the fridge for up to 3 days. Just make sure to cover it to prevent it from drying out.
- Can I freeze the sponge biscuit?
