Keto Tiramisu Affogato | Hot Espresso Melting Over Sugar-Free Mascarpone Ice Cream
I first made this on a hot afternoon when I was craving tiramisu but had zero energy to layer cookies and cream for hours. I had a scoop of homemade sugar-free mascarpone ice cream sitting in my freezer and a shot of espresso waiting to be brewed, and I just poured one over the other. One bite in, I knew I’d stumbled onto something better than the original dessert – it’s faster, it’s low carb, and that hot-meets-cold moment when the espresso melts the edges of the ice cream is honestly magic. I’ve made this dozens of times since, and one small trick (whipping the mascarpone just until it holds soft peaks, not stiff ones) is what keeps the texture silky instead of grainy.

- Quick to Serve: Ready to serve in under 5 minutes once the ice cream is frozen.

- Customizable & Versatile: Easily made dairy-forward or dairy-free with simple swaps.
Key Ingredients Breakdown
Mascarpone Cheese
This is what gives the ice cream that dense, silky texture you remember from real tiramisu. It’s naturally low in carbs and has a mild, slightly tangy flavor that pairs so well with coffee. If you can’t find mascarpone, full-fat cream cheese works in a pinch, though it will taste a touch tangier.
Heavy Cream
Heavy cream is what makes this ice cream scoopable instead of icy. Whipping it adds air, so the texture stays soft even straight from the freezer. Coconut cream is a good dairy-free substitute, though the flavor will lean slightly more tropical.
Powdered Erythritol or Allulose
This is my sweetener of choice because it dissolves smoothly and doesn’t leave that cooling aftertaste some keto sweeteners have. Allulose especially helps keep the ice cream soft instead of rock-hard in the freezer. You can swap in any powdered keto sweetener you already have on hand.
Vanilla Extract
Vanilla rounds out the flavor and makes the ice cream taste rich rather than just sweet. Use a good quality pure extract if you can – it makes a real difference here since there are so few ingredients.
Espresso
Freshly brewed espresso is the star of the “affogato” part of this dessert. It needs to be hot, strong, and poured right before serving so it partially melts the ice cream. If you don’t have an espresso machine, very strong brewed coffee works too.
Cocoa Powder
A light dusting of unsweetened cocoa powder on top gives that classic tiramisu look and a slightly bitter contrast to the sweet ice cream. Cacao powder works the same way if that’s what you have.
Rum Extract (Optional)
A few drops of rum extract brings in that classic tiramisu flavor without adding any alcohol or sugar. It’s optional, but I almost always add it because it makes the dessert taste more authentic.

Impressive Presentation
It looks impressive in a glass, so it works for date night or a small dinner party.
Pro Tips
- Whip the mascarpone just until smooth and creamy – overwhipping can make it curdle or turn grainy.
- Fold the whipped cream into the mascarpone gently, in stages, so the ice cream base stays light and airy.
- Freeze the ice cream in a shallow container so it freezes faster and scoops more easily.
- Let the ice cream sit at room temperature for 5 minutes before scooping if it’s very firm.
- Pour the espresso over the ice cream right at the table so your guests see (and hear) that sizzle-melt moment.
Storage & Reheating
Store any leftover ice cream (without the espresso poured on) in an airtight, freezer-safe container for up to 2 weeks. Because this ice cream has no gums or stabilizers, it freezes a bit harder over time, so let it sit at room temperature for 5 to 10 minutes before scooping again. Do not store the assembled affogato, since the espresso will melt the ice cream completely within minutes – always pour it fresh right before eating. Espresso itself is best made right before serving and shouldn’t be reheated, as reheated coffee can taste bitter and flat.

kcalThis Keto Tiramisu Affogato is a warm shot of espresso poured right over a scoop of rich, homemade sugar-free mascarpone-vanilla ice cream, finished with a dusting of cocoa powder. It tastes exactly like tiramisu in a glass – creamy, coffee-forward, and a little bit boozy if you add the rum extract – but it comes together in minutes once your ice cream is frozen. It’s a no-bake, low-carb dessert that feels fancy enough for guests but easy enough for a Tuesday night.

Ingredients
- For the Sugar-Free Mascarpone Ice Cream:
1 cup (226g) mascarpone cheese, softened
1 cup (240ml) heavy whipping cream, cold
1/3 cup (53g) powdered erythritol or allulose
1 teaspoon pure vanilla extract
1/4 teaspoon fine sea salt
1/2 teaspoon rum extract (optional)
- For the Affogato:
4 shots (about 4 oz / 120ml total) hot brewed espresso
2 teaspoons unsweetened cocoa powder, for dusting
4 sugar-free chocolate-covered espresso beans, for garnish (optional)
Directions
- In a large mixing bowl, use a hand mixer or stand mixer to beat the softened mascarpone with the powdered sweetener, vanilla extract, rum extract (if using), and salt on medium speed for about 1 to 2 minutes, until it’s smooth and creamy. Be careful not to overmix, since mascarpone can turn grainy or start to separate if it’s whipped too long.
- In a separate bowl, pour in the cold heavy cream and whip it on medium-high speed for 2 to 3 minutes, until soft peaks form. The peaks should hold their shape but still look soft and glossy, not stiff and dry.
- Add about a third of the whipped cream into the mascarpone mixture and fold it in gently with a spatula to loosen the base. Then add the rest of the whipped cream in two more additions, folding gently each time until the mixture is smooth, light, and fully combined with no streaks.
- Spoon the mixture into a shallow, freezer-safe container and smooth the top with your spatula. Cover with a lid or plastic wrap pressed directly onto the surface to prevent ice crystals, and freeze for at least 4 hours, or until firm enough to scoop.
- When you’re ready to serve, brew your espresso shots fresh and hot, right before assembling the dessert.
- Scoop about 1/2 cup of the frozen mascarpone ice cream into each of 4 small glasses or cups. Dust each scoop lightly with cocoa powder.
- Pour one hot shot of espresso directly over each scoop of ice cream at the table, letting it pool and melt around the edges. Top with a chocolate-covered espresso bean if using, and serve right away with a small spoon.
Recipe Notes
- You’ll need a hand mixer or stand mixer to get the ice cream base light and smooth – whisking by hand won’t give you the same airy texture.
- A shallow container (like a loaf pan) helps the ice cream freeze faster and more evenly than a deep, narrow one.
- If your mascarpone mixture looks slightly grainy after mixing, it likely got a bit too warm or overmixed – it will still taste good, just slightly less silky.
- For a true tiramisu feel, crumble a low-carb almond flour cookie over the top before pouring the espresso.
- Make sure your espresso is truly hot when you pour it, since that temperature contrast is what makes this dessert special.

Frequently Asked Questions
Can I make this ahead of time for a dinner party?
Yes, the ice cream base can be made up to 2 weeks ahead and kept frozen. Just brew the espresso and assemble everything right before serving so the ice cream doesn’t melt too fast or lose its texture.
Is this recipe dairy-free friendly?
You can make a dairy-free version by swapping the mascarpone and heavy cream for full-fat coconut cream and a dairy-free cream cheese alternative. The texture will be slightly less rich, but the coffee flavor still comes through beautifully.
Do I need an espresso machine to make this?
No, you don’t. If you don’t have an espresso machine, brew a small amount of very strong coffee using a moka pot, French press, or even instant espresso powder mixed with hot water – just keep it concentrated so it doesn’t water down the ice cream.
Can I use a different sweetener?
Yes, any powdered keto-friendly sweetener you like works here, including monk fruit blends or a powdered erythritol-monk fruit mix. Just avoid granulated sweeteners, since they won’t dissolve as smoothly into the mascarpone.
