Description
This bright and airy Italian-inspired sponge cake is soaked in a zesty limoncello syrup and finished with a luxurious, cloud-like mascarpone frosting. It is a refreshing and sophisticated dessert that balances citrus tang with silky richness, making it perfect for any gathering.
Ingredients
- 1 1/2 cups all-purpose flour
- 1 teaspoon baking powder
- 4 large eggs, separated
- 1 cup granulated sugar (divided)
- 2 lemons, zested and juiced
- 1/2 cup limoncello liqueur
- 1/4 cup water
- 8 ounces mascarpone cheese, room temperature
- 1 cup heavy whipping cream
- 1/2 cup powdered sugar
- 1 teaspoon vanilla extract
Instructions
- Preheat your oven to 350°F (175°C) and grease and line two 8-inch round pans with parchment paper.
- In a small bowl, whisk together the flour and baking powder, then set aside.
- In a clean bowl, beat the egg whites until they form soft peaks.
- In a separate large bowl, beat the egg yolks with granulated sugar until pale and thick, then stir in the lemon zest, lemon juice, and limoncello.
- Gently fold the dry ingredients into the yolk mixture, followed by the beaten egg whites using a spatula to maintain the air.
- Divide the batter between the pans and bake for 22 to 25 minutes until a tester comes out clean.
- Prepare a soaking syrup by simmering limoncello with water and a bit of sugar in a saucepan until dissolved; once cooled, brush over the cake layers.
- Whip the mascarpone until smooth, then add heavy cream, powdered sugar, and vanilla, whisking until thick and fluffy.
- Layer the frosting between the cake rounds and over the exterior, then refrigerate for at least four hours before serving.
Notes
For the best results, ensure your eggs are at room temperature to achieve maximum volume when beating the whites. To get perfectly clean slices, use a sharp knife dipped in warm water and wiped dry between each cut. This cake tastes even better after the flavors meld in the fridge overnight.
