Why you’ll love this Lemon Tiramisu:

  • Lemon Soaked Lady Fingers – Lady fingers are quickly dunked in a lemon simple syrup (limoncello is delish, but optional!)
  • Lemon Curd – My easy homemade lemon curd is super tart & ultra silky!
  • Whipped Mascarpone – Instead of making whipped cream and folding it into mascarpone, I’ve made things easier – we make the mascarpone mixture first and then beat in heavy cream – it fluffs up within the mixture!
  • Make-Ahead – Tiramisu needs to chill overnight so the layers can really meld together, making this the perfect make-ahead dessert!

Ingredient Overview:

As always, the full recipe with measurements & directions can be found in the recipe card at the bottom of this post. Use the table of contents (back at the top, below the first image, to navigate).

  • Lady Fingers – We’re using store bought for ease, of course! You can find these with the Italian food items in many major grocery stores.
  • Mascarpone –
  • Heavy Cream – Be sure to get heavy whipping cream (or heavy cream – same thing), not half and half or whole milk! Those other ones won’t whip up.
  • Butter – I always use salted buter because in my experience, it lends the best flavor, but feel free to use unsalted butter if that’s what you prefer.
  • Lemon Juice – I recommend using fresh squeezed!

Recipe Substitutions & Variations:

  • Dairy-free – Use your favorite dairy-free heavy cream. For the mascarpone, I *think* (but haven’t tried it) dairy-free cream cheese could work instead. Otherwise, try making your own dairy-free mascarpone.

How to Make this Lemon Tiramisu Recipe:

Step 1: Make the Lemon Curd. Cook together eggs, lemon zest & juice, sugar, and salt until thickened. Strain and stir in butter and vanilla. Let cool completely. This lemon curd is so versatile – I even use it as the filling in my Lemon Meringue Pie Cookies!

Step 2: Make the Lemon Simple Syrup. Heat together lemon juice, water, sugar, and lemon peel until sugar is dissolved. Strain and set aside.

Step 3: Make the Whipped Mascarpone. Beat together mascarpone, powdered sugar, vanilla, and salt in a large bowl. Beat in the heavy cream for 1-2 minutes, until thick and fluffy! (This mixture is also used as the frosting for my Tiramisu Cookies!)

Step 4: Assemble & Chill: Quickly dunk lady fingers in the lemon simple syrup & place in a single layer in the bottom of a large baking dish. Spread half the mascarpone on, then add half the lemon curd.

Repeat one more time with all 3 components, then chill overnight!

Expert Baking Tips:

  • Oven Thermometer – An oven thermometer will tell you if your oven is actually running at the temperature you set it to. Your oven may not be accurate. Accurate oven temperature is crucial for most bakes, so I leave an oven thermometer in at all times to keep an eye on my oven’s calibration.
  • Kitchen Scale – A food scale is the best way to make sure your flour is at the proper weight, since amounts will vary SO widely based on how you measure it, as well as the measuring cup you use, as they are not standardized.

FAQs:

Can I double or halve this recipe?

You’d need quite the large pan to double it, so I’m not sure if that’s practical. You’d likely need to just make two batches of the recipe. But, you can certainly try it if you have a large enough pan. You can also halve the recipe if needed.

Ingredients 

For the Lemon Curd

  • zest of 2 large lemons
  • 3/4 cup + 2 tbsp granulated sugar , 184 grams
  • 3/4 cup + 1 tbsp lemon juice, about 4-5 medium lemons, but measure it out to be sure! 198 grams
  • 4 large large eggs, at room temperature
  • pinch of salt
  • 1/2 cup salted butter, cubed, 113 grams
  • 1/2 tsp vanilla extract

For the Lemon Simple Syrup

  • 2/3 cup water, 160 grams
  • 1/3 cup granulated sugar , 70 grams
  • 1 lemon peeled
  • 1/3 cup freshly squeezed lemon juice, 81 grams
  • 1/4 tsp vanilla extract

For the Whipped Mascarpone Cream

  • 8 ounces mascarpone, 226 grams
  • 1 and 1/3 cups powdered sugar , 153 grams
  • 1 tbsp vanilla extract , 15 grams
  • pinch of salt
  • 3/4 cup + 2 tbsp cold heavy cream, (I know this measurement is annoying, but 1 full cup made slightly too much of the cream) 210 grams

For Assembly

  • 26 lady fingers, for an 8×11 pan, more for 9×13 pan – see note below

Instructions 

  • Make the Lemon Curd: Make my Homemade Lemon Curd according to the recipe linked here. Once it's done and the butter/vanilla have been added, pop it in the fridge (uncovered is fine) until it's cold. This can be made up to 2 days in advance – be sure to cover it if storing in the fridge more than 1-2 hours.
    zest of 2 large lemons, 3/4 cup + 2 tbsp granulated sugar , 3/4 cup + 1 tbsp lemon juice, 4 large large eggs, at room temperature , pinch of salt, 1/2 cup salted butter, cubed, 1/2 tsp vanilla extract
  • Make the Lemon Simple Syrup: Add all ingredients except for the vanilla into a medium saucepan and heat over medium high heat, until it comes to a simmer and the sugar is dissolved. You can check this by rubbing a bit of the mixture between clean fingers – you shouldn't feel any sugar granules. Remove from the heat and strain out the peels, then stir in the vanilla. Pop in the fridge to cool.
    2/3 cup water, 1/3 cup granulated sugar , 1 lemon peeled , 1/3 cup freshly squeezed lemon juice, 1/4 tsp vanilla extract
  • Make the Whipped Mascarpone: In a medium bowl, beat together the mascarpone, powdered sugar, vanilla, and salt until smooth. Pour in the cold heavy cream and beat on low just until combined, then mix on high speed for about 1 minute, until the mixture is thick and smooth.
    8 ounces mascarpone, 1 and 1/3 cups powdered sugar , 1 tbsp vanilla extract , pinch of salt, 3/4 cup + 2 tbsp cold heavy cream
  • Prep for Assembly: Make sure your lemon curd and lemon simple syrup are cold. Spray an 8×11 or 9×13 baking dish with nonstick spray. Figure out how the lady fingers will fit in the baking dish while they're dry, and use a sharp knife to cut any that need it to fit.
  • Assemble: Divide the lady fingers in half and begin with the first half – dunk each quickly on each side into the cold lemon simple syrup. Make sure they are moistened – but not waterlogged or soggy. Layer evenly in the bottom of the pan. Spread half the mascarpone on top, then half the lemon curd. Repeat this with the second half of each the lady fingers & simple syrup, mascarpone, and lemon curd.

  • Chill: Don't worry about covering the pan – anything will just stick and make a mess. Pop the pan in the fridge to chill overnight before serving.
  • Serve & Store: Once chilled, slice and enjoy! Store leftovers in the fridge, covered since now the insides are cut and exposed to air, for 2-3 days.

Notes

Lady Fingers: If you’re using an 8×11 pan, 26 lady fingers will do the trick (1 full package plus a few more from a second, however this can vary by brand so check how many are in a package). If you’re using a 9×13 pan, you’ll need 3 packages of lady fingers.

    So tasty! I did the corn-starch lemon curd and was perfectly happy. I used a big tray, so 400gr lady fingers, which were very “thirsty” so I had to make more syrup along the way 🙂 I would try it again with eg strawberries. Thanks!

      Thanks so much for taking the time to leave a review, Alma! And thanks for the feedback about needing the extra syrup.

    This was soooo delicious and very rich! Definitely want to try it with a berry sauce or compote next time. Maybe a strawberry or blueberry ❤️
