Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

For the Lemon Syrup:

• Fresh lemon juice

• Water

• Granulated sugar

For the Tiramisu:

• Ladyfingers (savoiardi biscuits)

• Mascarpone cheese (softened)

• Heavy cream

• Powdered sugar

• Lemon zest

• Vanilla extract

• Fresh lemon juice

• Lemon curd (optional for extra richness)

• Fresh mint (optional for garnish)

Directions

1. Prepare the Lemon Syrup:

   • In a small saucepan, I combine fresh lemon juice, water, and sugar. I bring it to a simmer and stir until the sugar dissolves completely. I let it cool to room temperature before using it to soak the ladyfingers.

2. Make the Tiramisu Filling:

   • In a large mixing bowl, I whisk the softened mascarpone cheese, powdered sugar, lemon zest, vanilla extract, and fresh lemon juice until smooth and creamy.

   • In a separate bowl, I whip the heavy cream until stiff peaks form, then gently fold it into the mascarpone mixture. This gives the tiramisu its signature creamy texture.

   • For extra lemon flavor and richness, I sometimes stir in a few tablespoons of lemon curd at this stage (optional, but highly recommended).

3. Assemble the Tiramisu:

   • I quickly dip each ladyfinger into the cooled lemon syrup, making sure not to soak them too long, and lay them in the bottom of a 9×9-inch dish or similar-sized pan.

   • I spread half of the lemon mascarpone mixture evenly over the ladyfingers.

   • I repeat the layers with another round of dipped ladyfingers and the remaining mascarpone mixture.

4. Chill and Serve:

   • I cover the tiramisu and refrigerate it for at least 4 hours or overnight, allowing the flavors to meld and the dessert to firm up.

   • Just before serving, I garnish the top with extra lemon zest and fresh mint for a burst of color and freshness.

Servings and timing

This recipe serves 6–8 people and takes about 30 minutes total — 10 minutes for prep and 20 minutes for assembling. Don’t forget to chill for at least 4 hours before serving!

Variations

If I want an even more decadent version, I can add a layer of lemon curd in between the mascarpone layers for extra creaminess and flavor. I’ve also used a mix of lemon and lime juice for a citrus twist, or swapped lemon zest for orange zest for a slightly different flavor profile.

storage/reheating

I store leftovers in an airtight container in the fridge for up to 2–3 days. Tiramisu is best enjoyed cold, so there’s no need to reheat it. I recommend letting it sit at room temperature for a few minutes before serving for the best texture.

FAQs

Can I make this tiramisu ahead of time?

Yes, this dessert is even better when made ahead! I typically make it the night before so it has time to chill and set in the fridge.

What can I substitute for ladyfingers?

If I can’t find ladyfingers, I use sponge cake or even a soft pound cake cut into slices. The texture may change slightly, but it still works well.

How can I make this dessert dairy-free?

To make this dairy-free, I use a dairy-free mascarpone substitute and coconut cream in place of the heavy cream. There are great alternatives available that mimic the texture and flavor of traditional mascarpone.

Can I freeze Lemon Tiramisu?

I don’t recommend freezing tiramisu as it may affect the texture of the cream. It’s best stored in the fridge and eaten within a few days.

Can I make this with a different fruit?

Yes! If I prefer a different flavor, I can swap out lemon for berries like strawberries or raspberries for a similar approach, or even peaches for a more summery vibe.

Conclusion

Lemon Tiramisu is a delightful twist on the classic Italian dessert, offering a fresh, citrusy flavor that brightens up any meal. I love how easy it is to make, and the lemony zing makes it perfect for spring and summer gatherings. Whether I’m serving it for a casual family dinner or an elegant occasion, this dessert is always a crowd-pleaser.
