Step-by-Step Directions
- Preheat your oven: Preheat the oven to 325°F. Prepare a 10-inch springform pan by lining the bottom with parchment paper, avoiding greasing the sides.
- Mix the eggs and sugar: In an electric mixer, beat together the sugar, eggs, and vanilla extract on medium-high speed for about 10 minutes until it’s foamy and pale.
- Incorporate the flour: Reduce the mixer speed to medium-low and gradually sprinkle in the flour. Stop the mixer once the flour is fully incorporated.
- Add melted butter: Remove 1 to 2 cups of batter and mix with melted butter. Gently fold this mixture back into the original batter, avoiding over-mixing.
- Bake the cake: Pour the batter into the prepared springform pan. Bake for about 45 minutes or until the top springs back when gently pressed. Start checking at the 40-minute mark.
- Cool the cake: Allow the cake to cool completely in the pan for at least a couple of hours. Gently run a sharp knife around the edges before releasing the sides of the pan.
- Prepare the lemon curd: In a small saucepan, combine egg yolks, sugar, lemon juice, and zest. Cook on medium-low heat, stirring constantly for about 10 minutes until it thickens.
- Finish the lemon curd: Remove from heat, gradually stirring in the butter until smooth. Cover and chill in the refrigerator.
- Make the whipped cream: Whip the cream with icing sugar and vanilla extract until firm peaks form.
- Combine with lemon curd: Fold half of the chilled lemon curd into the whipped cream until fully blended.
- Assemble the cake: If using, sprinkle the sponge cake with Limoncello. Add the lemon mousse over the cake and chill for several hours or overnight.
- Serve the cake: Once chilled, loosen the mousse with a knife, transfer to a serving plate, spread reserved lemon curd on top, and pipe or dollop whipped cream around the edges.
- Prepare candied lemon peel: Slice a lemon into thick slices, remove the flesh, and simmer the peel in a mixture of sugar and water for 15-20 minutes. Coat in additional sugar to finish.
Common Mistakes to Avoid & Pro Tips
- Over-beating the eggs: Avoid over-whipping as it can lead to a dense cake instead of a light sponge.
- Not checking for doneness: Start checking your cake at 40 minutes to prevent over-baking.
- Skipping cooling time: Letting the cake cool in the pan is crucial to maintaining its structure.
Pro Tips:
- Measure your ingredients accurately for the best results.
- Chill your tools (like the mixing bowl) before whipping cream for better volume.
- If making ahead, prepare the lemon curd a day in advance for the best flavor development.
