Ingredients
Method
Preheat the oven to 320°F (160°C). Line the bottoms of two 6-inch (15 cm) pans with parchment paper.
In a large bowl, beat the eggs, sugar, and salt for 7–10 minutes, until pale and fluffy.
- Add the oil and vanilla extract; mix on low speed until combined.
- In a small bowl, whisk together milk and sour cream, and warm slightly to room temperature.
- Sift flour with baking powder. Add to the egg mixture alternately with the milk–sour cream mixture
- Divide the batter evenly between the two pans.
- Bake for 40–45 minutes, until a toothpick comes out clean.
- Cool in the pan for about 30-40 minutes, then transfer to a rack. Once cooled completely, wrap in plastic and refrigerate for 2–4 hours — it will be easier to slice.
Make the Cream
- In a large mixing bowl, combine mascarpone, powdered sugar, and cold heavy cream.
- Beat with a mixer on medium speed until the mixture thickens and forms soft peaks (do not overbeat).
- Add vanilla extract and mix briefly to combine.
- → The cream should be smooth, fluffy, and stable.
Assemble the Cake
- Slice each sponge into 2–3 layers (depending on thickness).

- Lightly soak each layer with milk or simple syrup
- Spread a generous layer of cream and add fresh berries between the layers
- Cover the top and sides of the cake with cream
- Wrap the cake in plastic wrap and refrigerate for at least 3–5 hours to set.
Decorate with berries or white chocolate ganache if desired.
Notes
Tips for Best Results
- Sour cream in the batter makes the sponge extra tender.
- Baking at a lower temperature (320°F) keeps the cake light and prevents dryness.
- The mascarpone cream is stable without gelatin, smooth and fluffy.
- For a taller or more decorated cake, double the cream amount and use it for both filling and finishing.
