The Keto Tiramisu Recipe That Will Blow Your Mind

If you’re living that low-carb, high-fat life (a.k.a. keto), you might have thought some of your favorite desserts were off the menu for good. Tiramisu, with its layers of soft ladyfingers, rich mascarpone cream, and that hit of espresso, might feel like one of those things you just can’t have anymore. But guess what? Keto Tiramisu exists, and it’s every bit as decadent as the original—without kicking you out of ketosis.

This keto-friendly tiramisu recipe hits all the right notes: creamy, coffee-soaked, and just sweet enough. The best part? You don’t need to sacrifice flavor for macros. So, if you’re missing a slice of Italian heaven but want to keep things low-carb, you’re in for a treat.

Why Make Tiramisu Keto-Friendly?

Classic tiramisu uses ladyfingers (which are loaded with carbs), sugar, and sometimes a splash of sugary liqueur. All of this is a no-go for a ketogenic diet where the goal is to minimize carbs. But, by making a few swaps—like using almond flour instead of regular flour for the ladyfingers and sweetening with keto-approved alternatives like erythritol—you can still enjoy this dessert without the sugar overload.

And let’s be real, a dessert like tiramisu isn’t just a “sometimes” treat—it’s the kind of thing you crave for its layers of texture and flavor. With this keto version, you can indulge, stay on track, and not feel like you’re missing out.

The Ingredients You’ll Need

Before we get into the step-by-step details, let’s look at what makes this Keto Tiramisu a diet-friendly option. We’ll break it down into two major components: the ladyfingers and the mascarpone cream filling.

For the Keto Ladyfingers:

  • Almond flour – 1 cup
  • Coconut flour – 2 tbsp (this keeps it from being too dense)
  • Eggs – 4, separated
  • Erythritol (or monk fruit sweetener) – 1/3 cup (granular)
  • Baking powder – 1 tsp
  • Vanilla extract – 1 tsp
  • Cream of tartar – 1/4 tsp (to stabilize the egg whites)

For the Mascarpone Filling:

  • Mascarpone cheese – 1 1/2 cups (make sure it’s at room temperature)
  • Heavy whipping cream – 1 cup
  • Egg yolks – 4
  • Erythritol (powdered) – 1/2 cup
  • Vanilla extract – 1 tsp
  • Unsweetened cocoa powder – for dusting

For the Espresso Layer:

  • Brewed espresso – 1 cup (cooled)
  • Rum or keto-friendly coffee liqueur – 2 tbsp (optional but adds that extra zing)

Making Keto Ladyfingers

Most tiramisu recipes start with store-bought ladyfingers, but to keep things keto, you’ll need to make your own. Don’t worry—it’s way easier than it sounds.

  • Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
  • Separate your eggs. In one bowl, beat the egg yolks and 1/3 cup of erythritol until pale and creamy. Stir in the vanilla extract.
  • Whip the egg whites. In a separate bowl, using an electric mixer, beat the egg whites with cream of tartar until soft peaks form. Slowly add 1 tbsp of erythritol and beat until stiff peaks form.
  • Combine the dry ingredients. In a separate bowl, whisk together the almond flour, coconut flour, and baking powder.
  • Fold the egg yolk mixture into the dry ingredients until just combined. Then, gently fold in the whipped egg whites, being careful not to deflate the mixture.
  • Pipe the batter. Transfer the batter to a piping bag (or use a plastic bag with the tip cut off) and pipe 3-inch long ladyfingers onto your prepared baking sheet.
  • Bake for 12-15 minutes or until the ladyfingers are golden and firm to the touch. Set aside to cool.

Preparing the Mascarpone Filling

  • Whip the heavy cream. Using an electric mixer, beat the heavy cream until stiff peaks form. Set aside.
  • Beat the egg yolks. In a separate bowl, whisk together the egg yolks and powdered erythritol. Heat the mixture gently over a double boiler (or a heat-safe bowl over simmering water), stirring constantly, until it thickens slightly—about 5 minutes. Remove from heat and allow it to cool.
  • Mix in the mascarpone. Once the yolk mixture has cooled, add the mascarpone cheese and vanilla extract. Beat until smooth and creamy.
  • Fold in the whipped cream. Gently fold the whipped cream into the mascarpone mixture, being careful not to overmix. You want it light and fluffy.

Assembling the Keto Tiramisu

Now comes the fun part—layering the tiramisu. Grab a dish (an 8×8-inch pan works well), your cooled ladyfingers, espresso, and mascarpone filling.

  • Soak the ladyfingers. Briefly dip each ladyfinger into the cooled espresso. Don’t let them soak too long—you want them moist but not soggy.
  • Layer the tiramisu. Start with a layer of soaked ladyfingers at the bottom of your dish. Then, spread half of the mascarpone mixture on top. Add another layer of ladyfingers, followed by the remaining mascarpone filling.
  • Dust with cocoa powder. Lightly dust the top with unsweetened cocoa powder using a fine mesh sieve.
  • Chill. Cover the tiramisu with plastic wrap and refrigerate for at least 4 hours, or overnight if you can wait. This lets the flavors meld together and the texture firm up.

Keto Tiramisu Tips & Tricks

  • Espresso strength: For the best flavor, use a strong espresso or brewed coffee. If you don’t have an espresso machine, you can use instant espresso powder mixed with hot water.
  • Alcohol options: Traditional tiramisu uses rum or Marsala wine, but for keto purposes, you can opt for a splash of rum extract or skip the booze altogether.
  • Sweeteners: Erythritol or monk fruit sweeteners work well for this recipe, but you can use whatever low-carb sweetener you prefer. Just make sure it’s powdered for the mascarpone mixture to avoid any gritty texture.
  • Ladyfinger substitutes: If you’re in a rush, you can use store-bought keto cookies or cakes, but nothing beats homemade. Plus, making your own gives you full control over the ingredients.

The Perfect Keto Tiramisu: Macros Breakdown

You’re probably wondering: how does this version stack up nutritionally? The beauty of keto desserts is that you get all the flavor and texture of the original, but with macros that won’t mess with your carb limit.

Here’s a rough estimate of the macros for one serving (assuming the recipe serves 8):

  • Calories: 350
  • Fat: 32g
  • Carbs: 6g (Net carbs: 3g)
  • Protein: 7g

Common Keto Tiramisu Mistakes (And How to Avoid Them)

Making tiramisu from scratch can seem intimidating, especially when you’re trying to keep it keto-friendly. But don’t sweat it—here are a few common issues and how to avoid them:

  • Soggy Ladyfingers: If you dip the ladyfingers for too long, they’ll absorb too much liquid and turn mushy. A quick dunk is all you need.
  • Grainy Filling: This happens if your sweetener isn’t powdered. Always opt for powdered erythritol or monk fruit to ensure a smooth, creamy filling.
  • Lumpy Mascarpone Mixture: If the mascarpone is too cold, it won’t mix well with the yolk and whipped cream. Let it sit at room temperature for a bit before mixing.
  • Lack of Espresso Flavor: If you’re not getting that strong coffee kick, try using a more concentrated brew or add a little more espresso. You want the coffee flavor to shine.

Variations of Keto Tiramisu

Feeling adventurous? Here are a few ways to put your own spin on this keto classic:

  • Chocolate Keto Tiramisu: Add a layer of shaved dark chocolate (90% cocoa or more) between the ladyfingers and mascarpone filling for an extra rich treat.
  • Berry Keto Tiramisu: Toss in a handful of fresh berries between the layers for a fruity twist. Blueberries or raspberries are low in carbs and add a nice tangy contrast to the sweet mascarpone.
  • Matcha Tiramisu: Swap the espresso for matcha tea and dust the top with matcha powder instead of cocoa. You’ll get a beautiful green color and a subtle earthy flavor that pairs perfectly with the mascarpone.

Conclusion 

Keto Tiramisu might sound like an impossible dream, but with the right ingredients and a bit of patience, it’s totally doable—and absolutely worth it. You get all the classic flavors without the sugar spike, and the satisfaction of knowing you can have dessert and stick to your keto goals at the same time.

Whether you’re whipping this up for a special occasion or just because you’re craving something sweet, this recipe will deliver. So, go ahead, take a bite of this keto-friendly tiramisu, and savor every creamy, coffee-soaked bite. You’ve earned it.
