Refreshing Lemon Tiramisu: A Zesty Twist on a Classic Dessert
There’s something undeniably magical about the way a lemon tiramisu fills your kitchen with its bright, citrusy aroma. I still remember the first time I made this dessert for a summer barbecue at our house in Portland. I was nervous—tiramisu is a classic, and messing with tradition can be risky! But when my husband, David, took his first bite and his eyes lit up, I knew I’d struck gold.
After years of tweaking this recipe in my bakery, Sophie’s Sweet Haven, I’ve landed on a version that’s zesty, creamy, and just the right amount of sweet. This lemon tiramisu is perfect for warm days, holiday gatherings, or whenever you need a little sunshine on your plate. Let’s dive in and make some dessert memories together!
Lemon Tiramisu Recipe
Refreshing Lemon Tiramisu: A Zesty Twist on a Classic Dessert
Ingredients
Lemon Curd:
- 100 ml from 3-4 lemons fresh lemon juice
- 1 teaspoon lemon zest
- 3 large eggs
- 3/4 cup 150 grams granulated sugar
- 3 1/2 tablespoons 50 grams unsalted butter
- Pinch of fine sea salt
Tiramisu Cream:
- 1 1/4 cups 300 grams mascarpone cheese
- 1/2 cup 60 grams powdered sugar
- 1/2 cup 100 ml lemon curd (from above)
- 3/4 cup 200 ml heavy cream
Other:
- 28 ladyfinger cookies
- 1 cup water
- 2 tablespoons granulated sugar
- 1 tablespoon fresh lemon juice
Instructions
Make the Lemon Curd
- Combine the ingredients: In a small saucepan, whisk together 100 ml fresh lemon juice, 1 teaspoon lemon zest, 3 large eggs, 3/4 cup granulated sugar, and a pinch of fine sea salt. I like to use a whisk to make sure everything’s fully combined before heating.
- Cook low and slow: Place the saucepan over low heat and stir constantly with a wooden spoon or spatula. This usually takes me about 8-10 minutes. You’re looking for the mixture to thicken enough to coat the back of a spoon. Don’t crank up the heat to speed things up—I learned this the hard way when I ended up with scrambled eggs instead of curd!
- Add the butter: Remove the pan from the heat and stir in 3 1/2 tablespoons unsalted butter until it’s completely melted and smooth. The buttery aroma at this stage is heavenly.
- Strain and chill: Pour the curd through a fine-mesh sieve into a bowl to remove any bits of zest or cooked egg. Cover with plastic wrap (press it directly onto the surface to prevent a skin from forming) and refrigerate for at least 1 hour. This makes about 1 cup of curd, and you’ll use half for the cream and half for drizzling.
Make the Tiramisu Cream
- Whip the cream: In a large mixing bowl, whip 3/4 cup heavy cream until soft peaks form. I use a hand mixer for this, and it takes about 2-3 minutes on medium speed. You want the cream to hold its shape but still look soft and billowy.
- Mix the mascarpone base: In another bowl, whisk together 1 1/4 cups mascarpone cheese, 1/2 cup powdered sugar, and 1/2 cup of the chilled lemon curd until smooth. Don’t worry if it looks a bit loose at first—mine always does!
- Fold it together: Gently fold the whipped cream into the mascarpone mixture using a spatula. I like to tell my students to think of this as a gentle hug—you want to keep all that air in the cream. Mix until just combined for a light, fluffy texture.
Prepare the Ladyfingers
- Make the soaking syrup: In a shallow dish, stir together 1 cup water, 2 tablespoons granulated sugar, and 1 tablespoon fresh lemon juice until the sugar dissolves. This takes about a minute of stirring. The syrup should be lightly sweet with a hint of lemon.
- Dip the ladyfingers: Working one at a time, dip each of the 28 ladyfingers into the syrup for about 1-2 seconds per side. They should be moist but not falling apart. I’ve ruined a batch by soaking them too long, so trust me on this one—quick dips are key!
Assemble the Lemon Tiramisu
- First layer: Arrange half of the soaked ladyfingers (about 14) in a single layer in a 9×9-inch or similar-sized serving dish. I like to overlap them slightly to create a sturdy base. Spread half of the tiramisu cream over the ladyfingers, smoothing it out with a spatula.
- Second layer: Add another layer of the remaining soaked ladyfingers, then top with the rest of the tiramisu cream. Smooth the top for a pretty finish.
- Drizzle the curd: Spoon or drizzle the remaining 1/2 cup lemon curd over the top. I like to use a piping bag for a decorative swirl, but a spoon works just as well. The bright yellow curd makes this dessert look as good as it tastes!
- Chill it: Cover the dish with plastic wrap and refrigerate for at least 2 hours, though 4-6 hours is even better. This lets the flavors meld and the ladyfingers soften into that classic tiramisu texture.
- Serve and enjoy: Slice into squares or scoop into bowls, and serve chilled. The smell alone will have your neighbors knocking!

Pro Tips for Lemon Tiramisu Success
After years of making this dessert, I’ve picked up a few tricks to ensure it turns out perfectly every time:
- Don’t rush the curd: Low heat is crucial to avoid curdling. If you’re worried about lumps, keep a thermometer handy—the curd should reach about 170°F (77°C).
- Chill everything: Cold mascarpone and cream whip better and hold their shape. I pop my mixing bowl in the fridge for 10 minutes before starting.
- Test your ladyfingers: Not all brands absorb liquid the same way. If yours seem too soft after a quick dip, reduce the soaking time to 1 second per side.
- Make it ahead: This dessert tastes even better the next day. I often make it the night before a party to save time (and stress!).
- Avoid overmixing the cream: Folding too much can deflate the whipped cream, making the texture dense. Stop as soon as it’s combined.
Here’s where most people go wrong: they soak the ladyfingers for too long or skip chilling the dessert. I can’t tell you how many times I’ve seen soggy tiramisu at potlucks! Be patient, and you’ll be rewarded with a dessert that’s light and luscious.
Variations and Customizations for Lemon Tiramisu
One of the things I love about lemon tiramisu is how adaptable it is. Here are a few variations I’ve tried at the bakery or for family gatherings:
- Berry Twist: Add a layer of fresh raspberries or blueberries between the ladyfingers and cream for a pop of color and flavor. Summer berries pair beautifully with lemon.
- Limoncello Kick: Replace 2 tablespoons of the water in the soaking syrup with limoncello for an adult-friendly version. Nonna Rosa would approve!
- Gluten-Free Option: Use gluten-free ladyfingers. I’ve tested Schar’s brand, and it works wonderfully.
- Mini Tiramisu Cups: Assemble in individual glasses or mason jars for a cute, portable dessert. Perfect for parties!
- Herbal Infusion: Add a teaspoon of finely chopped fresh basil or mint to the lemon curd for a subtle, sophisticated twist. I discovered this by accident when experimenting for a spring event, and it was a hit.
Feel free to make this recipe your own. My daughter Emma loves sprinkling crushed meringue on top for extra crunch—don’t worry if it looks messy at first, hers always does too!
Storing and Serving Your Lemon Tiramisu
Lemon tiramisu is a dream for entertaining ahead of time. Store it covered in the fridge for up to 3 days; the flavors only get better with time. I don’t recommend freezing, as the cream can separate and the ladyfingers get soggy.
Serve it chilled, straight from the fridge, with a dusting of powdered sugar or a few lemon zest curls for extra flair. I love pairing it with a scoop of vanilla ice cream or a cup of David’s freshly roasted coffee for a perfect finish. If you’re feeling fancy, garnish with fresh berries or a sprig of mint. For portion sizes, a 9×9-inch dish yields about 8 generous servings or 12 smaller ones—perfect for sharing (or not!).
Conclusion
This lemon tiramisu is more than just a dessert—it’s a way to bring a little joy to your table. Whether you’re making it for a special occasion or just because it’s Tuesday, I hope this recipe fills your kitchen with as much happiness as it does mine. I can still hear Nonna Rosa saying, “The secret ingredient? Patience.” Take your time, enjoy the process, and don’t be afraid to make it your own. If I can survive the Great Soufflé Disaster of 2019, you can nail this lemon tiramisu! Share your results with me—I’d love to hear how it turns out in your kitchen. Happy baking!
