Ingredients You’ll Need

Each ingredient in this Rhubarb Tiramisu Recipe plays a key role, from the tartness of fresh rhubarb to the creamy mascarpone and fluffy whipped cream. Grab the freshest rhubarb available for the best flavor, and make sure your mascarpone and cream are well chilled – it makes a big difference for the texture and stability of the cream filling.

Rhubarb: Fresh rhubarb is essential—avoid any leaves as they’re toxic. Look for firm stalks with vibrant color.
Granulated sugar: You’ll use this both to sweeten the compote and the tiramisu filling, balancing the tart rhubarb.
Lemon juice: Adds brightness and helps enhance the tang of rhubarb in the compote.
Cornstarch: This thickens the rhubarb compote without clouding its flavor.
Water: For simmering the syrup and compote, nothing fancy needed here.
Vanilla bean paste: Adds rich, warm vanilla notes that complement the rhubarb beautifully.
Egg yolks (pasteurized): Provides richness and structure to the tiramisu filling—pasteurized to keep it safe without cooking.
Mascarpone cheese: The creamy heart of tiramisu—it should be cold to whip well into the filling.
Heavy cream: Also cold, so it whips to perfect stiff peaks for that light texture.
Ladyfingers: The base sponge: these soak beautifully in the rhubarb syrup to add moisture and flavor without getting soggy.

Variations

I like to tweak this Rhubarb Tiramisu Recipe depending on what mood I’m in or what ingredients I have on hand. Don’t hesitate to make it your own, whether by adjusting sweetness or trying out different textures.

Berry twist: Sometimes I swap half of the rhubarb with fresh raspberries or strawberries for an extra fruity punch. It adds vibrant color and complements the tang nicely.
Dairy-free option: For friends sensitive to dairy, using coconut cream instead of heavy cream and a plant-based mascarpone alternative works surprisingly well.
Alcohol-free soak: Traditionally tiramisu uses coffee and liquor, but here the rhubarb syrup replaces that. You could add a splash of orange blossom water or rose water for a different aromatic profile.
Less sweet: If you prefer desserts on the tarter side, reduce sugar in the compote and syrup slightly—rhubarb’s natural acidity will shine through.

How to Make Rhubarb Tiramisu Recipe

Step 1: Make the Rhubarb Compote

Start by chopping your rhubarb into small, uniform pieces and toss them into a saucepan with sugar and lemon juice. I find stirring gently with a rubber spatula helps break down the rhubarb evenly without mashing it into a puree. Once the mixture bubbles, reduce the heat and let it simmer, stirring occasionally for 10-12 minutes until it thickens nicely.

Next, mix cornstarch with cold water, then pour that slurry into your simmering compote. Keep stirring constantly until it thickens further, about a minute. Pour the compote into a shallow bowl, cover it with plastic wrap touching the surface to prevent a skin, and chill until cold. This wait is worth it for the compote’s perfect texture!

Step 2: Prepare the Rhubarb Syrup

In a separate saucepan, combine water, sugar, and a small amount of chopped rhubarb. Bring it to a boil, then let it simmer gently for about 3 minutes. Turning off the heat, stir in vanilla bean paste and let it steep for 10 minutes to infuse that lovely vanilla aroma.

After steeping, strain the syrup through a fine mesh sieve, discarding the rhubarb bits, and set aside to cool completely. This syrup will soak your ladyfingers, making them tender and packed with rhubarb flavor without turning soggy.

Step 3: Whisk the Tiramisu Filling

Here’s where things get fun: start by whisking sugar, egg yolks, and vanilla paste in a heatproof bowl until you see a fluffy, lighter mixture — 1-2 minutes should do it. Then, place that bowl over simmering water to create a double boiler and keep whisking steadily for about 5 minutes. This cooks the egg yolks gently and dissolves the sugar, giving you a silky, safe-to-eat custard base.

After removing from heat and drying the bowl’s bottom, whisk in the cold mascarpone until smooth with no lumps left. Separately, whip the heavy cream to stiff peaks—firm enough to hold its shape. Gently fold the whipped cream into the mascarpone mixture, being mindful not to deflate it. This makes the filling luxuriously light yet creamy.

Step 4: Assemble Your Rhubarb Tiramisu

Having a 27×20 cm or 23×23 cm dish ready is ideal. Quickly dip each ladyfinger twice on both sides into the cooled rhubarb syrup—don’t soak too long or they’ll get mushy. Lay a neat, single layer of soaked ladyfingers on the dish.

Spoon half of your mascarpone cream over them, spreading gently for an even layer. Dollop half the rhubarb compote on top and spread carefully without mixing completely. Repeat with another ladyfinger layer, mascarpone, then the rest of the compote.

Cover the tiramisu tightly with plastic wrap and refrigerate for a minimum of 4 hours, although overnight is best to let the flavors meld beautifully.

How to Serve Rhubarb Tiramisu Recipe

A layered dessert with three main layers is shown on a white plate with a white marbled texture surface. The bottom layer is creamy white and smooth, the middle layer consists of light tan sponge or biscuit pieces soaked in a light syrup, and the top layer is a bright red fruit sauce that looks slightly thick and shiny, gently dripping down the sides. A spoon with a bite of the dessert is placed on the plate revealing the moist, soft texture of the biscuit layer and creamy filling. Some dry biscuit pieces are scattered near the plate.

Garnishes

I personally love finishing my rhubarb tiramisu with a few ribbons of fresh rhubarb or a light dusting of powdered sugar to add a delicate, elegant touch. A sprig of fresh mint can also brighten the presentation and add a pop of green that complements the pink hues nicely.

Side Dishes

This dessert is rich, so I like to keep the sides light — a simple fresh fruit salad or a crisp green salad with citrus vinaigrette pairs beautifully. If you’re serving it after a big meal, a cup of herbal tea or a light espresso balances the creaminess perfectly.

Creative Ways to Present

For special occasions, I’ve served this Rhubarb Tiramisu layered in individual glass jars or clear cups, allowing the pretty layers to shine through. It’s an easy way to personalize portions and offers a visually stunning presentation that guests adore. You can also try adding edible flowers on top for a fresh, seasonal vibe.

Make Ahead and Storage

Storing Leftovers

I usually cover leftover tiramisu tightly with plastic wrap and store it in the fridge. It keeps wonderfully for up to 3 days, and honestly, the flavors deepen, so it can taste even better the next day. Just make sure to serve chilled for the best texture.

Freezing

Freezing tiramisu can be tricky because of the cream, but if you want to preserve it, I recommend freezing in airtight containers and thawing slowly overnight in the fridge. The texture might change slightly, becoming a bit less fluffy, but the flavor remains delightful.

Reheating

I don’t recommend reheating Rhubarb Tiramisu Recipe since it’s best enjoyed cold and creamy. If your tiramisu has been frozen, simply defrost it in the fridge and serve chilled—this helps maintain that lovely texture and fresh flavors.

FAQs

Can I use rhubarb from the freezer for this Rhubarb Tiramisu Recipe?

Yes, you can use frozen rhubarb if fresh isn’t available, but make sure to fully thaw and drain any excess liquid to avoid watering down the compote or syrup. The flavor may be slightly less vibrant, so taste and adjust sugar accordingly.
Is it safe to use raw eggs in this tiramisu recipe?

This recipe uses pasteurized egg yolks, which are safe to consume without further cooking. If you can’t find those, look for pasteurized liquid egg products or cook the yolks gently over the double boiler as described to ensure safety.
Can I substitute ladyfingers with another type of biscuit?

Definitely! Sponge cake or savoiardi biscuits work well, and even light, mildly sweet cookies can substitute. Just make sure they absorb the rhubarb syrup nicely without disintegrating.
How long should I let the tiramisu set in the fridge?

I recommend letting it chill for at least 4 hours, but overnight is even better. This allows the flavors to meld and the ladyfingers to soften perfectly without getting overly soggy.
Can I prepare this Rhubarb Tiramisu Recipe ahead of a party?

Absolutely! In fact, preparing it a day ahead means your tiramisu will taste even better by party time. Just keep it covered and refrigerated until serving.
