This Strawberry Shortcake Layer Cake is made with a light and fluffy sponge cake, creamy mascarpone filling, and fresh sliced strawberries. It’s perfect for birthdays, spring and summer gatherings, Mother's Day, or any family celebration.
Preheat the oven to 350°F (180°C). Line the bottom of a 9.5–10-inch (24–25 cm) springform pan with parchment paper and lightly grease the sides with sunflower oil.In a large mixing bowl, beat the eggs with the sugar, vanilla sugar, and a pinch of salt on high speed. Continue mixing until the mixture is pale, airy, and has tripled in volume.
Sift the flour and baking powder into the egg mixture in batches. Gently fold after each addition with a silicone spatula. Try not to overmix so you keep as much air in the batter as possible.
Pour the batter into the prepared pan and smooth the top. Bake for about 35 minutes, or until the cake is golden and a toothpick inserted into the center comes out clean.Allow the sponge cake to cool completely in the pan at room temperature before slicing it into layers.
In a medium bowl, whip the mascarpone with the sugar and vanilla extract until creamy. If the mixture is too thick, add a little cold heavy cream and mix until it becomes smooth and easy to spread.Once the cake has completely cooled, carefully slice it horizontally into two even layers.
Place the first sponge layer on a serving plate or cake stand. Spread half of the mascarpone cream over the top, then arrange half of the sliced strawberries over the cream.
Place the second sponge layer on top. Spread the remaining mascarpone cream over the cake and arrange the rest of the strawberries on top.
Decorate with extra strawberries and fresh mint if you like. Chill the cake in the refrigerator for at least 1 hour before slicing. This helps the layers set and makes the cake easier to serve.
