It’s a cake that feels both classic and modern, combining the timeless softness of a vanilla sponge with the luxurious creaminess of mascarpone and the brightness of lemon. The result is a dessert that’s light yet rich, fragrant yet balanced, and perfect for any occasion—from afternoon tea to festive celebrations. The Bourbon vanilla adds depth and warmth, while the lemon mascarpone cream brings freshness and a subtle tang that cuts through the sweetness. This cake is a celebration of texture and flavor, where every bite melts in the mouth and leaves a lingering note of vanilla and citrus.
The Essence of the Cake
The beauty of this cake lies in its balance. The sponge is airy and tender, made with real Bourbon vanilla for an authentic, aromatic flavor. The mascarpone cream is smooth and luscious, infused with lemon zest and juice for a refreshing contrast. Together, they create a dessert that’s both comforting and refined. The combination of vanilla and lemon is timeless—one brings warmth and sweetness, the other brightness and zest. The mascarpone adds a creamy richness that ties everything together, making this cake irresistibly smooth and flavorful.
The Importance of Bourbon Vanilla
Bourbon vanilla, named after the former name of Réunion Island (Île Bourbon), is one of the most prized varieties of vanilla in the world. It’s known for its deep, creamy aroma and complex flavor profile, with notes of caramel and floral sweetness. Using real Bourbon vanilla—whether in the form of a pod, paste, or extract—elevates the cake from ordinary to exceptional. It infuses the sponge with a natural fragrance that artificial vanilla can’t replicate. The tiny black seeds from the vanilla pod also add a beautiful speckled appearance to the cake, a sign of authenticity and quality.
The Role of Lemon Mascarpone Cream
The lemon mascarpone cream is what transforms this cake into something truly special. Mascarpone, an Italian cream cheese, is rich and velvety, with a mild flavor that pairs beautifully with both sweet and tangy ingredients. When combined with lemon zest and juice, it becomes light, refreshing, and slightly tart—an ideal complement to the sweetness of the sponge. The cream can be used as a filling between layers, a topping, or even as a frosting for a more rustic presentation. Its smooth texture and balanced flavor make it versatile and irresistible.
Choosing the Right Ingredients
Every ingredient in this cake plays a crucial role in achieving the perfect texture and flavor.
Flour
Use cake flour or all-purpose flour sifted twice for a light, airy sponge. Cake flour has a lower protein content, which helps create a tender crumb.
Eggs
Eggs are the backbone of a sponge cake. They provide structure, moisture, and richness. Room-temperature eggs whip better, trapping more air for a fluffy texture.
Sugar
Fine caster sugar dissolves easily and helps stabilize the whipped eggs. It also adds sweetness without making the cake heavy.
Butter
Unsalted butter adds richness and flavor. It should be melted and cooled slightly before being incorporated into the batter to maintain the sponge’s lightness.
Bourbon Vanilla
Use a whole vanilla pod, vanilla paste, or high-quality extract. The flavor should be natural and aromatic, not artificial.
Mascarpone
Choose fresh, high-quality mascarpone for the cream. It should be smooth and thick, not watery.
Lemon
Fresh lemon juice and zest are essential for the cream. They add brightness and balance the richness of the mascarpone.
Cream
Heavy cream or whipping cream helps lighten the mascarpone mixture, giving it a mousse-like texture.
Ingredients for 8–10 Servings
For the Vanilla Sponge Cake
- 4 large eggs, room temperature
- 120 g (½ cup) caster sugar
- 120 g (1 cup) cake flour, sifted
- 40 g (3 tablespoons) melted unsalted butter
- 1 Bourbon vanilla pod (or 1 teaspoon vanilla paste or extract)
- A pinch of salt
the Lemon Mascarpone Cream
- 250 g (1 cup) mascarpone cheese
- 200 ml (¾ cup) heavy cream
- 80 g (⅓ cup) icing sugar
- Zest of 1 lemon
- 1 tablespoon fresh lemon juice
- ½ teaspoon vanilla extract
For Decoration
- Lemon zest curls
- Fresh berries or edible flowers (optional)
- Powdered sugar for dusting
Preparing the Vanilla Sponge Cake
- Preheat the oven: Set the oven to 180°C (350°F). Grease and line a 20 cm (8-inch) round cake pan with parchment paper.
- Prepare the vanilla: Split the vanilla pod lengthwise and scrape out the seeds. Add them to the sugar to infuse the flavor.
- Whip the eggs and sugar: In a large bowl, beat the eggs, sugar, and vanilla seeds with an electric mixer for 8–10 minutes until the mixture is pale, thick, and tripled in volume. The batter should form a ribbon when lifted.
- Fold in the flour: Sift the flour and salt together, then gently fold into the egg mixture in three additions using a spatula. Be careful not to deflate the batter.
- Add the butter: Pour the melted butter down the side of the bowl and fold gently until just combined.
- Bake: Pour the batter into the prepared pan and smooth the top. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean.
- Cool: Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
Preparing the Lemon Mascarpone Cream
- Whip the cream: In a chilled bowl, whip the heavy cream until soft peaks form. Set aside.
- Mix the mascarpone: In another bowl, beat the mascarpone with icing sugar, lemon zest, lemon juice, and vanilla extract until smooth.
- Combine: Gently fold the whipped cream into the mascarpone mixture until fully incorporated. The cream should be light, fluffy, and smooth.
- Chill: Refrigerate for at least 30 minutes before using to allow it to firm up slightly.
Assembling the Cake
- Level the cake: Once the sponge is completely cool, trim the top if necessary to create an even surface.
- Slice the cake: Cut the sponge horizontally into two or three layers, depending on your preference.
- Add the cream: Spread a generous layer of lemon mascarpone cream between each layer. Use an offset spatula to smooth it evenly.
- Top and decorate: Spread the remaining cream over the top and sides of the cake. Decorate with lemon zest curls, fresh berries, or edible flowers.
- Chill before serving: Refrigerate the cake for at least 1 hour before serving to allow the flavors to meld and the cream to set.
The Perfect Texture and Flavor
The ideal vanilla sponge cake should be light, airy, and moist, with a delicate crumb that melts in the mouth. The Bourbon vanilla gives it a deep, aromatic sweetness, while the lemon mascarpone cream adds a refreshing contrast. The combination of soft sponge and creamy filling creates a luxurious texture that’s both comforting and refined. The lemon zest enhances the vanilla’s warmth, creating a balance that’s neither too sweet nor too tangy.
Variations and Add-Ins
- With berries: Add fresh raspberries or blueberries between the layers for a fruity twist.
- With syrup: Brush the sponge with a light lemon or vanilla syrup for extra moisture.
- With nuts: Sprinkle toasted almonds or pistachios on top for crunch.
- With white chocolate: Fold melted white chocolate into the mascarpone cream for a richer flavor.
- With citrus: Replace lemon with orange or lime for a different citrus profile.
- Mini cakes: Bake the sponge in smaller molds for individual servings.
Tips for Success
- Use room-temperature ingredients: This ensures even mixing and a smooth batter.
- Don’t overmix: Overmixing can deflate the batter and make the sponge dense.
- Check the oven temperature: An oven thermometer helps ensure accurate baking.
- Cool completely before frosting: Warm cake can cause the cream to melt.
- Chill the cream: Cold mascarpone and cream whip better and hold their shape.
- Use fresh lemons: Fresh juice and zest provide the best flavor and aroma.
Presentation Ideas
- Classic style: Serve the cake simply dusted with powdered sugar and lemon zest.
- Elegant look: Decorate with piped mascarpone cream rosettes and edible flowers.
- Rustic charm: Spread the cream casually and top with fresh berries.
- Layered beauty: Show off the layers by serving a slice on a white plate with a drizzle of lemon syrup.
Pairing Suggestions
The delicate flavors of this cake pair beautifully with light, aromatic beverages:
- Tea: Earl Grey, chamomile, or jasmine tea complement the vanilla and lemon notes.
- Coffee: A cappuccino or latte enhances the creaminess of the mascarpone.
- Wine: A sweet dessert wine like Moscato d’Asti or a sparkling Prosecco pairs perfectly.
