Step 1: Prepare the Sponge Cake
- Preheat the oven to 175°C (350°F). Grease and line an 8-inch round cake pan with parchment paper.
- In a large bowl, whisk the egg yolks and half of the sugar (75g) until pale and creamy.
- Add vanilla extract to the yolk mixture and whisk until combined.
- In a separate bowl, beat the egg whites with the salt until soft peaks form. Gradually add the remaining sugar (75g) and beat until stiff peaks form.
- Gently fold the egg whites into the yolk mixture in batches, alternating with the sifted flour. Use a spatula to combine, taking care not to deflate the batter.
- Pour the batter into the prepared cake pan and smooth the top.
- Bake for 20-25 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the cake to cool completely in the pan, then transfer to a wire rack.
Step 2: Make the Mascarpone Cream
- In a large bowl, beat the mascarpone cheese, powdered sugar, and vanilla extract until smooth and creamy.
- In a separate bowl, whip the chilled heavy cream to stiff peaks.
- Gently fold the whipped cream into the mascarpone mixture until fully combined. Add lemon or orange zest for a citrusy touch, if desired.
Step 3: Assemble the Cake
- Slice the cooled sponge cake horizontally into two layers.
- Place one layer on a serving plate or cake board. Spread a generous amount of mascarpone cream evenly over the surface.
- Add the second cake layer on top and spread the remaining mascarpone cream over the top and sides of the cake.
Step 4: Decorate and Serve
- Decorate with fresh berries, a dusting of powdered sugar, cocoa powder, or grated chocolate for a simple and elegant finish.
- Refrigerate the cake for at least 2 hours to set before serving.
Tips for Success
- Room Temperature Ingredients: Ensure eggs and mascarpone are at room temperature for smooth mixing.
- Chill the Cream: Keep the heavy cream and mixing bowl cold for the best whipping results.
- Customize Flavors: Add a splash of coffee, liqueur, or fruit puree between the layers for a unique twist.
