Instructions
Make the Sponge Cake
Preheat oven to 350°F. Grease an 8-inch round cake pan and line the bottom and sides with parchment paper.
In a heatproof bowl, combine whole eggs, egg yolks, sugar, and salt. Beat with an electric mixer on high speed.
Place the bowl over a pan of simmering water and continue beating until the mixture is warm.
Remove from heat and beat until the mixture is thick, pale, and tripled in volume, about 5–7 minutes. It should fall and leave visible ribbons on top from the lifted beaters.
Sift together cake flour and cornstarch. Gently fold into the egg mixture using a rubber spatula.
Pour batter into prepared pan and bake for 30 minutes. The cake should be light brown, look dry on top, and begin to pull away from the edges of the pan. A skewer inserted into the center should come out clean.
Cool in pan for 10 minutes, then turn out onto a wire rack, remove parchment, and cool completely.
Level the cooled cake if needed. Slice horizontally into two even layers, about 3/4-inch thick.
Make the Lemon Syrup
In a small saucepan, combine sugar and water over medium heat. Stir until sugar dissolves, about 5 minutes.
Remove from heat and cool completely, then stir in limoncello (or lemon juice + lemon extract if non-alcoholic version preferred).
Line a 9-inch springform pan with parchment paper (grease lightly first so it sticks).
Place one cake layer in the center of the pan, cut side up.
Brush evenly with half of the lemon syrup. Set aside while you prepare the filling.
Make the Lemon Mascarpone Cream
In a large bowl, beat room temperature (68–72°F) mascarpone cheese, sugar, and lemon juice until smooth and fluffy.
Mix in lemon paste (or lemon extract) and yellow food color, if using.
In a small heatproof bowl, combine limoncello (or water for non-alcoholic version) and sprinkle gelatin on top to bloom. Let stand 5 minutes.
Heat the gelatin mixture in the microwave for about 10 seconds until fully dissolved and liquid.
Let cool slightly until fluid but not hot to the touch, then slowly beat into the mascarpone mixture.
Add the 2 cups heavy cream and beat on medium-high speed until thick, fluffy, and mousse-like, about 2–3 minutes. Stop mixing when it holds soft peaks and is still slightly pourable.
Assemble the Torte
Spoon half of the mascarpone cream over and around the cake layer in the springform pan, filling the gap between the cake and pan and covering the first cake layer completely.
Pick up and drop, or gently rap the pan on the counter repeatedly to settle the filling and remove air pockets. Smooth the cream over the cake evenly.
Place the second cake layer on top, cut side down. Brush with remaining lemon syrup.
Spread remaining mascarpone cream over the top, smoothing evenly. Rap the pan again to settle and remove gaps and air bubbles. Smooth the surface with an offset spatula. The filling should come nearly to the top of the pan. Refrigerate for at least 4 hours or overnight, until fully set.
Unmold and Decorate
Remove the springform collar and peel away parchment.
Smooth the sides with a warm offset spatula to remove bubbly texture, if desired.
Transfer whipped cream to a piping bag fitted with a large open star tip and pipe a border around the top edge.
Garnish with lemon chocolate curls, if desired.
Store the cake lightly covered in plastic wrap in the refrigerator until ready to serve. Serve chilled
Notes
Make Ahead: This torte is ideal for making ahead. Prepare it 1 or 2 days in advance and keep refrigerated until ready to serve.Storage: Store covered in the refrigerator for up to 5 days. For best texture, serve chilled.Important Tip: Make sure the mascarpone is fully at room temperature before mixing. Cold mascarpone can cause the gelatin to seize, resulting in a lumpy texture instead of a smooth cream.Substitutions: If using lemon extract instead of lemon paste, use 2 teaspoons extract in place of 2 tablespoons paste. Adjust to taste if needed.Swap in Elderflower liqueur in even amounts for the Limoncello.For a no-alcohol version, swap the 1/4 cup limoncello in the soaking syrup for 1/4 cup lemon juice + 1 teaspoon lemon extract.
