Vietnamese Coffee Tiramisu

This Vietnamese coffee tiramisu swaps sugar for condensed milk for a silkier, bolder cream layer. The overnight trick makes it unforgettable. Get the recipe →

Vietnamese coffee tiramisu is the dessert that ruined regular tiramisu for me — and I mean that as the highest compliment. This recipe gives you a step-by-step guide to building a layered, make-ahead dessert with condensed milk, mascarpone cheese, ladyfingers, and bold brewed coffee that comes out silkier than anything from a bakery case.

This Vietnamese coffee tiramisu uses sweetened condensed milk instead of sugar, egg yolks tempered over a double boiler, and whipped heavy cream folded into the mascarpone filling to create a cloud-soft, bittersweet, deeply caffeinated dessert that sets beautifully overnight.

I first tried a version of this at a tiny Vietnamese-owned café where the owner served it in small mason jars with a dusting of cocoa — I went home, pulled out my 9×9, and didn’t stop testing until I got it exactly right.

How Do You Make Vietnamese Coffee Tiramisu at Home?

Vietnamese coffee tiramisu is a no-bake layered dessert made from coffee-soaked ladyfingers and a silky mascarpone cream sweetened with condensed milk instead of sugar, chilled until the flavors meld into something rich, bold, and perfectly balanced.

1. Combine ¾ cup brewed coffee with 1 tbsp amaretto in a bowl until blended and fragrant.
2. Whisk 3 egg yolks and ⅓ cup condensed milk over a double boiler until the mixture turns pale yellow and slightly thickened, about 3–5 minutes.
3. Fold 8 oz mascarpone cheese, 2 tbsp brewed coffee, and 1 tsp vanilla extract into the warm egg mixture until completely smooth.
4. Whip 1 cup heavy cream to stiff peaks, then gently fold it into the mascarpone mixture to keep it light and airy.
5. Dip each ladyfinger briefly in the coffee mixture and layer them tightly across the bottom of a 9×9 baking dish.
6. Spread half the cream over the ladyfingers, repeat the layers, dust with cocoa powder, and refrigerate at least 6 hours before serving.

• Condensed milk vs. granulated sugar: Condensed milk adds caramel sweetness and body; sugar gives a cleaner, more neutral sweetness.
• Double boiler vs. raw egg yolks: Double boiler tempers the eggs for food safety and builds a stable, thick base; raw yolks skip the step but risk food safety and a looser filling.
• Brewed coffee vs. espresso: Brewed coffee gives a smoother, gentler coffee flavor; espresso delivers a more intense, concentrated bite.
• Whipped cream folded in vs. whipped cream omitted: Folded cream makes the filling airy and mousse-like; skipping it results in a denser, heavier layer.
• Overnight chill vs. 6-hour chill: Overnight is the move — the ladyfingers fully absorb the coffee and the cream firms up into clean, sliceable layers.

The overnight chill is non-negotiable for the cleanest slice — make it the night before, walk away, and let the fridge do all the work.

Why Will You Love This Vietnamese Coffee Tiramisu?

This Vietnamese coffee tiramisu recipe earns a permanent spot in your dessert rotation because it’s genuinely easier than it looks and tastes like something that took far more effort than it did.

• The texture is extraordinary. The condensed milk gives the mascarpone filling a subtle caramel richness, and folding in whipped cream makes it impossibly light — like a coffee mousse tucked between soft, coffee-drenched sponge fingers.
• No oven, no stress. This is a completely no-bake dessert. The most “cooking” you’ll do is stirring egg yolks over simmering water for five minutes — everything else is assembly and patience.
• The condensed milk does double duty. It sweetens the filling and adds a silky, glossy texture that sugar alone never achieves. In testing, I found that ⅓ cup hits exactly the right balance — sweet enough to round out the coffee’s bitterness, but not so sweet it becomes cloying.
• It feeds a crowd beautifully. A 9×9 pan gives you 9 generous servings, and it actually gets better the longer it sits — one of those rare recipes where making it two days ahead is genuinely recommended.
• It beats every store-bought version, no contest. Packaged tiramisu is watery and bland. This one has layers of actual flavor, with the bold coffee bite and milky sweetness of a Vietnamese iced coffee in every single forkful.

If you love layered coffee desserts, my creamy mango tiramisu with a tropical mascarpone filling uses the same base technique and is just as easy to pull off.

What Ingredients Do You Need?

This condensed milk tiramisu recipe keeps the ingredient list short and approachable — you likely have most of these on hand already, and each one earns its place in the final flavor. For a serving of 9, here’s everything you need:

Brewed Coffee

Amount	Ingredient
¾ cup	Brewed coffee (strong-brewed drip or cold brew concentrate works well; Vietnamese-style coffee brewed through a phin filter is ideal for the most authentic flavor)
1 tbsp	Amaretto (optional, but it adds a warm almond note that plays beautifully off the coffee — skip it for an alcohol-free version)

Mascarpone Filling

Amount	Ingredient
3	Egg yolks (large; use the freshest eggs you can find since they’re gently cooked rather than fully baked)
⅓ cup	Sweetened condensed milk (this replaces all the sugar — don’t swap for evaporated milk, which isn’t sweetened)
8 oz	Mascarpone cheese (full-fat, at room temperature so it folds in without lumps)
2 tbsp	Brewed coffee
1 tsp	Vanilla extract (pure, not imitation — it matters here)
1 cup	Heavy cream (cold from the fridge whips fastest to stiff peaks)

Tiramisu Assembly

Amount	Ingredient
40	Ladyfingers (crisp Italian savoiardi-style; avoid the soft, spongy kind which turn to mush when dipped)
1 tbsp	Cocoa powder (unsweetened; sifted for even coverage and no clumping)

Per Serving (approximate): ~385 calories · 6g protein · 32g carbs · 26g fat

One square is genuinely satisfying — pair it with an extra espresso shot or a small glass of cold water to balance the richness.

What Equipment Do You Need?

• 9×9 baking dish — the exact size for 40 ladyfingers in two even layers; don’t go smaller or you’ll have a towering, unstable stack.
• Small saucepan + heatproof bowl — for the double boiler setup; the bowl should sit over the water, not touch it.
• Hand mixer or stand mixer — essential for whipping the heavy cream to stiff peaks in under three minutes.
• Rubber spatula — for folding the whipped cream gently into the mascarpone without deflating all that air you just built.
• Shallow bowl — for dipping ladyfingers; wide enough to roll them without crowding.
• Fine mesh sieve or sifter — for dusting cocoa powder evenly across the top; do not skip this, nothing looks worse than clumpy cocoa powder.
• Offset spatula (optional) — makes spreading the mascarpone filling into a perfectly even layer much easier.
• Plastic wrap or lid — to cover the dish tightly before refrigerating; the filling picks up fridge odors fast if left uncovered.

How Do You Make Vietnamese Coffee Tiramisu Step by Step?

Making this Vietnamese coffee tiramisu is a straightforward process once you understand the order of operations — the filling comes together first, then you assemble everything quickly and let the fridge do the real work.

1. Make your coffee soak. Stir ¾ cup brewed coffee and 1 tbsp amaretto together in a shallow bowl. Set it aside — it should be at room temperature or cooler before you dip the ladyfingers, so the cookies absorb without immediately going soggy.
2. Set up your double boiler. Bring an inch or two of water to a gentle simmer in a small saucepan. Add the 3 egg yolks and ⅓ cup condensed milk to a heatproof bowl and set it over the simmering water, making sure the bowl doesn’t touch the water’s surface. Stir constantly — within 3–5 minutes the mixture will turn pale yellow and thicken slightly. [If the bowl is too hot and the eggs start to scramble at the edges, pull it off the heat immediately and keep stirring — the residual heat will finish the job without any visible curds.]
3. Build the mascarpone base. Remove the egg mixture from the heat and add the 8 oz mascarpone cheese, 2 tbsp brewed coffee, and 1 tsp vanilla extract. Mix until there are absolutely no lumps and the mixture is completely smooth and glossy. Work quickly so it doesn’t cool into a stiff mass before the cream is folded in.
4. Whip the cream. In a separate cold bowl, whip 1 cup heavy cream on high speed until stiff peaks form — the cream should hold a firm point when the beaters are lifted without drooping. [Don’t overwhip or the cream will turn grainy and butter-like, which will make the final filling feel gritty; stop the second you see firm, glossy peaks.]
5. Fold together gently. Add the whipped cream to the mascarpone mixture in two additions, folding with a rubber spatula using slow, deliberate strokes from the bottom of the bowl upward. The goal is to preserve as much air as possible — you want the filling to look light and mousse-like, not deflated and dense.
6. First layer of ladyfingers. Lightly dip each ladyfinger into the coffee mixture, about one second per side — enough to saturate the cookie without it falling apart in your hands. Arrange them snugly in a single layer across the bottom of your 9×9 dish. [If you’re using crisp Italian savoiardi, one second per side is enough; softer ladyfingers need even less time or they’ll disintegrate.]
7. First layer of cream. Scoop half the mascarpone filling over the ladyfingers and spread it into an even layer using an offset spatula or the back of a spoon. Every corner counts here — uneven spreading means one side of the pan sets firmer than the other.
8. Second layer of ladyfingers and cream. Repeat the dipping and layering process with the remaining ladyfingers, then spread the remaining mascarpone cream on top in one smooth, even layer.
9. Dust with cocoa and chill. Sift 1 tbsp unsweetened cocoa powder evenly over the top layer. Cover the dish tightly with plastic wrap and refrigerate for a minimum of 6 hours, or overnight for the best, cleanest slices. [The cocoa layer looks dry right after sifting but softens into a velvety, fudgy topping as the dessert chills — as Serious Eats notes in their tiramisu deep dive, cocoa powder actually helps bind moisture from the coffee soak and prevents the top from getting soggy.]

Pro Tips for Perfect Vietnamese Tiramisu Recipe Results

Getting your Vietnamese tiramisu recipe dialed in comes down to a handful of small, non-obvious details — the kind you only learn after making it wrong a couple of times.

Don’t rush the double boiler step. When you cook the egg yolks and condensed milk together over steam, you’re doing two things at once: pasteurizing the eggs for food safety and building a stable emulsion that can hold up the mascarpone without breaking.

According to Serious Eats’ science-backed tiramisu technique, heating the egg mixture over a water bath helps the proteins partially coagulate, which gives the mixture the structure it needs to whip up light and hold volume. Rushing this step — or skipping it entirely — means a looser filling that slides rather than holds.

Cold cream, cold bowl. I tested whipping the heavy cream at room temperature once and it took nearly double the time and never hit true stiff peaks. Keep the cream in the fridge until the exact moment you’re ready to whip it, and if your kitchen runs warm, chill the mixing bowl and beaters for five minutes in the freezer first. It makes a noticeable difference in how fast and how firmly the cream whips.

Dip fast, don’t soak. One second per side is genuinely all the ladyfingers need. In my first few batches I held them a full two to three seconds, and the bottom layer turned into a wet, collapsing sponge that completely ruined the texture. A quick dip leaves the cookies with a slightly firm center that softens beautifully during the overnight chill without going mushy.

Use room temperature mascarpone. Cold mascarpone straight from the fridge doesn’t incorporate smoothly — it leaves lumps in the filling that never fully disappear. Pull it out at least 30 minutes before you start, and the mixture will come together in seconds with no effort.

The overnight chill is the actual secret ingredient. After six hours the flavors are good; after eight or ten they’re genuinely better. The coffee deepens, the cream loses any faint eggy edge, and the whole dessert slices cleanly and holds its shape. I always make this the night before I need it — it’s one less thing to stress about, and the results are noticeably superior.

Troubleshooting: When Something Goes Wrong

Why did my mascarpone filling turn watery or lumpy?
This almost always happens when cold mascarpone hits a warm egg mixture — the temperature shock causes the fat to separate. Make sure your mascarpone is at room temperature before folding it in, and stir gently rather than beating aggressively once it’s in the bowl.

Why are my ladyfingers soggy all the way through?
They soaked too long in the coffee — even an extra second or two can push crisp savoiardi past the point of no return. Dip one side, flip immediately, and move on. The cookies continue to absorb liquid during chilling, so what feels slightly underdone right after assembly will be perfectly soft in the fridge.

Why did my whipped cream deflate when I folded it in?
The mascarpone mixture was likely still too warm when you added the cream. Let the mascarpone base cool to close to room temperature before folding — warm fat breaks down whipped cream quickly. Fold slowly and in two additions, not all at once.

Can I make this without the double boiler step?
You can, but the filling will be looser and the eggs won’t be pasteurized, which matters if you’re serving this to children, pregnant guests, or anyone immunocompromised. The double boiler only adds five minutes and makes the filling noticeably more stable and scoopable — it’s worth the extra pot.

Why doesn’t my tiramisu slice cleanly?
It almost certainly didn’t chill long enough. Six hours is the minimum; overnight is the sweet spot. If you’re in a hurry and cut at the four-hour mark, you’ll get the flavor but the slices will slump. Cover it and walk away — patience is the entire job here.

Variations & Ways to Customize

There are a few genuinely great ways to riff on this coffee tiramisu Vietnamese style without losing what makes it special.

• Holiday Spiced Version. Add ½ tsp cinnamon and a pinch of cardamom to the brewed coffee soak for a warm, spiced variation that’s perfect for fall and winter entertaining. The spices echo the flavors of Vietnamese cà phê trứng (egg coffee) and make the whole dessert feel seasonal without changing a single step.
• Vegan Swap. Replace the mascarpone with full-fat coconut cream cheese or a cashew-based cream cheese, use aquafaba whipped to stiff peaks in place of heavy cream, swap the egg yolks for 2 tbsp cornstarch cooked with the condensed milk over the double boiler, and use a vegan condensed coconut milk. The texture won’t be identical, but it’s surprisingly close. For a full guide to making dairy-free tiramisu work from the crust up, see our step-by-step matcha tiramisu that uses the same no-dairy technique.
• Biscoff Cookie Twist. Swap the ladyfingers for Biscoff cookies and add a thin layer of Biscoff spread under the first cream layer. The spiced caramel flavor of the cookies amplifies the coffee and condensed milk in a way that’s genuinely unexpected and addictive.
• Extra Boozy Version. Double the amaretto in the coffee soak and add a tablespoon of Kahlúa directly into the mascarpone filling. This is the version I make for dinner parties when I want people to actually talk about dessert — it tastes sophisticated without being over-the-top.

Can You Make Vietnamese Coffee Tiramisu Ahead of Time?

Serving: This tiramisu is best served cold, straight from the fridge, cut into neat squares with a sharp knife wiped clean between slices. Add a light extra dusting of cocoa powder right before you bring it to the table — it freshens the look and adds a little extra bittersweet contrast with each bite.

Storing: Cover the 9×9 dish tightly with plastic wrap or a fitted lid and refrigerate for up to 3 days. The ladyfingers will continue to soften as the days pass — by day three they’re fully saturated and more pudding-like than sponge-like, which some people love and others don’t. Day one and two are the sweet spot for both texture and flavor.

Reheating: This is a cold dessert — don’t reheat it. If you’ve frozen individual portions (which works surprisingly well), thaw them in the fridge for 6–8 hours before serving; the texture comes back close to the original, though the cream layer softens slightly. Never microwave tiramisu or the mascarpone will melt and the dessert will turn into a warm, sad puddle.
