This lemon tiramisu offers a fresh, no-bake alternative featuring ladyfingers soaked in tangy lemon syrup layered with a smooth mascarpone cream infused with lemon zest. Preparation is quick with no cooking required, making it ideal for spring and summer. The dessert chills for hours, allowing flavors to meld into a bright and creamy treat. Garnished with lemon slices, it delivers a balanced blend of citrus freshness and rich creaminess, perfect for gatherings.
Last summer my neighbor brought over an armful of lemons from her tree, more than anyone could reasonably use. I stood there with this sunny bounty and remembered how much I love the brightness of lemon but wanted something beyond the usual lemon bars. That afternoon I played around with a tiramisu concept, replacing the usual coffee with lemon syrup, and my kitchen smelled like sunshine for hours.
I made this for a book club meeting last spring and watched three people go completely silent after their first bites. The combination of tart lemon syrup soaking into the ladyfingers creates this almost custard like texture that nobody expects. Now my friends request it for every warm weather gathering.
Ingredients
- Lemon Syrup: The foundation of this dessert, so use fresh lemons for the brightest flavor
- Heavy cream: Must be cold to whip properly, so do not skip the chilling step
- Mascarpone cheese: Let it come to room temperature for the smoothest incorporation
- Ladyfinger cookies: Savoiardi are traditional and hold up better than soft sponge cake alternatives
- Powdered sugar: Dissolves beautifully into the cream without any grainy texture
- Vanilla extract: Pure vanilla adds depth that balances the sharp lemon notes
- Fresh lemon zest: Zest right before using for the most aromatic oils
Instructions
- Make the lemon syrup:
- Combine water, sugar, lemon juice and zest in a small saucepan over medium heat, stirring until sugar completely dissolves. Remove from heat and let it cool completely because warm syrup will make your ladyfingers fall apart.
- Prepare the mascarpone cream:
- Whip cold heavy cream with powdered sugar until stiff peaks form, then fold into beaten mascarpone mixed with vanilla and lemon zest. The mixture should be thick and airy, not runny.
- Dip and arrange ladyfingers:
- Quickly dip each ladyfinger in cooled syrup for just a second or two, then place half of them in a single layer in your dish. Trust your instinct on the dipping speed, too much soaking leads to mush.
- Layer the cream:
- Spread half of your mascarpone mixture evenly over the ladyfingers using an offset spatula or the back of a spoon. Take your time to make it smooth and level.
- Repeat the layers:
- Add another layer of dipped ladyfingers followed by the remaining mascarpone cream, smoothing the top completely. Cover tightly and refrigerate for at least 4 hours, though overnight is better.
- Garnish before serving:
- Add fresh lemon slices and extra zest right before serving for that pop of color and aroma.
My sister serves this with little glasses of limoncello and acts like she spent hours preparing something elaborate. The truth is it is mostly waiting time, but nobody needs to know that.
Make It Ahead
This tiramisu actually improves with time, so it is perfect for preparing the day before a party. The ladyfingers continue to soften and the lemon flavor permeates every layer.
Serving Suggestions
Cut this into small squares because it is richer than it appears. A little goes a long way and smaller portions let guests come back for seconds without feeling overwhelmed.
Variations To Try
Sometimes I swap in blood oranges when they are in season for a gorgeous pink hue and slightly different flavor profile. The technique stays exactly the same.
- Try adding fresh basil leaves between layers for an herbal surprise
- A tablespoon of limoncello in the syrup adds lovely depth for adult gatherings
- Greek yogurt can replace half the mascarpone for a lighter, tangier version
Every time I serve this, someone asks for the recipe and looks surprised when I explain how simple it really is. That is the magic of tiramisu, it seems impressive but relies on a few quality ingredients doing most of the work.
