A Fresh, Creamy Twist on Classic Tiramisu
Tiramisu is one of the most loved desserts in the world, and the lemon version might be its most refreshing cousin. Crisp ladyfingers are dipped in a bright lemon syrup, layered with a light mascarpone cream, and finished with silky homemade lemon curd. The result is creamy but not heavy, sweet but pleasantly tart, and much lighter than the coffee original.
There are no raw eggs in this recipe: the lemon curd is cooked, and the mascarpone cream is whipped with cream and powdered sugar only. It is also made entirely ahead of time, which makes it ideal for summer gatherings, Easter lunches, birthdays, or any day you want a dessert that is already waiting in the fridge.

Ingredient Notes
Ladyfingers. Use the crisp, dry Italian kind (savoiardi), not the soft sponge type. Crisp ladyfingers absorb the syrup without falling apart. A 200 to 250 g packet is usually enough.
Mascarpone. Keep it cold, and stir it only briefly. Overmixing can make it grainy or split.
Lemons. You need about 5 lemons in total. Zest them first, then juice them. Use fresh juice, because bottled juice tastes flat in a recipe where lemon is the main flavor.
Limoncello (optional). Two tablespoons in the syrup adds depth, but the dessert is just as good without it.
Short on time? You can use about 1½ cups (360 g) of good store-bought lemon curd. Homemade tastes fresher and is less sweet, but it is a fair shortcut.
Ingredients
For the lemon curd
- 2 large eggs
- 2 large egg yolks
- ¾ cup (150 g) granulated sugar
- Zest of 2 lemons
- ½ cup (120 ml) fresh lemon juice (about 3 lemons)
- A pinch of salt
- 6 tablespoons (85 g) cold unsalted butter, cubed
For the lemon syrup
- ½ cup (120 ml) water
- 3 tablespoons (40 g) granulated sugar
- ¼ cup (60 ml) fresh lemon juice
- Peel of 1 lemon, in wide strips
- 2 tablespoons limoncello (optional)
For the mascarpone cream
- 2 cups (500 g) cold mascarpone
- 1 cup (250 ml) cold heavy whipping cream
- ½ cup (60 g) powdered sugar
- 1 teaspoon vanilla extract
- Zest of 1 lemon
To assemble
- 24 to 30 crisp ladyfingers (savoiardi)
To decorate (optional)
- Lemon zest or thin lemon slices
- White chocolate shavings
- Fresh berries or mint leaves
Instructions
1. Make the lemon curd
In a medium saucepan, whisk together the eggs, egg yolks, sugar, lemon zest, lemon juice and salt. Place over low heat and cook, whisking constantly, for 8 to 10 minutes. The curd is ready when it is thick enough to coat the back of a spoon and leaves a clear line when you run a finger through it (about 170°F / 77°C). Do not let it boil, or the eggs will scramble.
2. Strain and cool the curd
Pour the curd through a fine sieve into a clean bowl. Whisk in the cold butter, a few cubes at a time, until smooth and glossy. Press plastic wrap directly onto the surface to prevent a skin from forming, and chill for at least 1 hour. It will thicken further as it cools.
3. Make the lemon syrup
Combine the water, sugar, lemon juice and lemon peel in a small saucepan. Heat, stirring occasionally, until the sugar dissolves and the syrup just begins to simmer. Remove from the heat, discard the peel, stir in the limoncello if using, and let cool completely.
4. Whip the mascarpone cream
In a large, cold bowl, whip the heavy cream to stiff peaks and set aside. In another bowl, gently stir the mascarpone with the powdered sugar, vanilla and lemon zest until just smooth. Fold in the whipped cream in two or three additions until you have a light, fluffy cream.
5. Build the first layer
Quickly dip each ladyfinger into the cooled syrup for 1 to 2 seconds per side and arrange in a single layer in a 9×13 inch (23×33 cm) dish, breaking pieces to fill gaps. Spread half of the mascarpone cream over the top. Drop spoonfuls of lemon curd (about one-third of the total) over the cream and gently swirl it in with a knife.
6. Build the second layer
Repeat with another layer of dipped ladyfingers, the remaining mascarpone cream, and another third of the curd, swirled in.
7. Finish and chill
Spread the last third of the curd over the top. Cover and refrigerate for at least 6 hours, ideally overnight, so the ladyfingers soften and the layers set into clean slices.
Tips for Success
- Do not soak the ladyfingers. One to two seconds per side is enough. They will keep absorbing moisture from the cream while the dessert chills.
- Keep the dairy cold. Cold cream whips better and cold mascarpone stays smooth, which gives you a firmer, more sliceable dessert.
- Swirl, do not stir. Mixing the curd into the cream completely will thin it out. A swirl gives the dessert its pretty ripples and keeps the layers stable.
- Cook the curd gently. Low heat and constant whisking are the secret to smooth curd without any scrambled bits. Always strain it.
- Plan ahead. The curd can be made up to 3 days in advance and kept in the fridge. The finished dessert tastes best the next day.
- Cut with a warm knife. Dip a sharp knife in hot water and wipe it dry between slices for clean edges.
Serving and Storage
Decorate just before serving with lemon zest, white chocolate shavings and berries. Serve straight from the fridge.
Keep covered in the refrigerator for up to 3 days. The ladyfingers will become softer each day, but the flavor stays good. Because the dessert contains fresh cream and mascarpone, do not leave it at room temperature for more than 2 hours.
Frequently Asked Questions
Does this tiramisu contain raw eggs?
No. The eggs are cooked into the lemon curd, and the mascarpone cream is made with whipped cream and powdered sugar only.
Can I make it without alcohol?
Yes. The limoncello is optional, and the syrup works well without it.
Can I use store-bought lemon curd?
Yes. Use about 1½ cups (360 g). Homemade curd is fresher and less sweet, but a good store-bought one saves time.
Why is my cream runny?
Usually because the cream or mascarpone was not cold enough, the cream was not whipped to stiff peaks, or too much curd was stirred in. Chill the bowl and beaters beforehand, and swirl the curd in lightly.
Can I make it in individual glasses?
Yes. Layer broken ladyfingers, cream and curd in 10 to 12 small glasses. Chill for at least 4 hours.
Can I use another citrus fruit?
Oranges, limes or a mix of lemon and lime work in the curd and syrup. Orange is sweeter, so reduce the sugar slightly.
