What Is Tiramisu?

Tiramisu is one of the most loved and iconic Italian desserts in the world. Traditionally, it’s made with layers of ladyfingers soaked in strong espresso or coffee, then topped with a rich and creamy mascarpone filling made with eggs and sugar. The final touch? A generous dusting of unsweetened cocoa powder.

This classic no-bake dessert is known for its light, creamy texture and bold coffee flavor. It’s elegant, comforting, and easy to customize—like this keto version that swaps out the carbs but keeps all the deliciousness.

Is Tiramisu Keto-Friendly?

Traditional tiramisu isn’t keto-friendly because it’s usually made with ladyfingers, sugar, and other ingredients that are high in carbs.

But the good news? You can still enjoy a delicious keto tiramisu by making a few simple swaps!

Instead of ladyfingers, we’ll make a soft low carb cake layer using a mix of almond flour and coconut flour. We also replace the sugar with a keto-friendly sweetener, so you still get all the rich, creamy flavor—without the extra carbs.

Ingredients For Keto Tiramisu

This keto tiramisu may look fancy, but you’ll be surprised at how simple the ingredients are! You likely already have most of them in your kitchen.

Cake Layer Ingredients

• Almond Flour & Coconut Flour – A combo of both gives the perfect soft, fluffy texture without being gritty or dry.
• Sweetener – Use your favorite keto-friendly option like erythritol, monk fruit, or allulose. Powdered works best for a smoother finish.
• Baking Powder – Helps the cake rise and gives it a light texture.
• Eggs – Use room-temperature eggs for better mixing and to avoid that eggy flavor.
• Butter – Unsalted works best in desserts like this.
• Almond Milk – Adds moisture to the cake. Coconut milk works too.
• Vanilla Extract – Adds flavor and richness—use the best quality you have.
• Salt – Just a pinch to bring out all the other flavors.

For Mascarpone Filling

• Mascarpone Cheese – Softened, so it blends easily and gives a creamy texture.
• Heavy Whipping Cream – Adds volume and makes the filling rich and smooth.
• Powdered Sweetener – Blends well without leaving lumps or grittiness.
• Vanilla Extract – For a touch of warm flavor.

For Coffee Syrup

• Espresso or Strong Coffee – Hot or cold brew works great. You can also go decaf or even use unsweetened hot chocolate as a twist.
• Dark Rum (Optional) – For that classic tiramisu flavor, but you can leave it out if you prefer.

How To Make This Delicious Keto Tiramisu

Making keto tiramisu at home is much easier than you’d expect. Just follow these simple steps to enjoy a creamy, low-carb dessert everyone will love:

Start by preparing the cake layer:

1. In a large bowl, whisk together all the dry ingredients until well combined. Next, add the wet ingredients and mix until the batter is smooth and no lumps remain.
2. Pour the batter into a prepared cake pan (lined or greased) and bake at 350°F (175°C) for 15–20 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.

Prepare the mascarpone filling:

1. In a mixing bowl, add all the ingredients for the mascarpone filling. Using a hand mixer or stand mixer, beat for about 3 minutes, until the mixture is smooth, creamy, and fluffy. This filling will give your cake that classic tiramisu flavor and creamy texture.

Make the coffee syrup:

1. Combine freshly brewed espresso coffee with a splash of rum to create a rich and aromatic syrup. This step is essential for achieving the signature coffee-soaked cake layers that tiramisu is known for.

Assemble the tiramisu cake. Once the cake has cooled, carefully slice it in half horizontally to create two layers. Place the bottom layer on your serving plate.

1. Drizzle half of the coffee syrup evenly over the cake.
2. Spread half of the mascarpone filling on top, smoothing it out with a spatula.
3. Add the second cake layer, pour over the remaining coffee syrup, and top with the rest of the mascarpone filling.

Finishing touches:

Dust the top with unsweetened cocoa powder for that classic tiramisu look. Refrigerate for at least 2 hours before serving—this helps the flavors meld and the dessert to set properly.

Tips For Making The Best Keto Tiramisu

Making keto tiramisu at home is easier than you think! Here are a few simple tips to help you get the best flavor and texture every time:

• Let the mascarpone sit at room temperature. Cold mascarpone can be hard to mix and might turn lumpy. Let it sit on the counter for 15–20 minutes so it softens up. This helps you get a smooth and creamy filling without overmixing.
• Dip the cake in coffee syrup. Instead of brushing the coffee syrup on the cake, you can gently dip each piece into the syrup for a stronger coffee flavor. Just don’t leave it in too long—you want it moist, not soggy.
• Use strong coffee or espresso. For that classic tiramisu flavor, use strong brewed coffee or espresso. It makes a big difference, especially in a sugar-free dessert, where you want the coffee to stand out.
• Let it chill before serving. After assembling your tiramisu, pop it in the fridge for at least 2 hours—overnight is even better. This helps the flavors blend and gives the dessert time to firm up so it’s easier to slice.
• Pick the right sweetener. Use a low carb sweetener that works well for baking, like powdered erythritol, monk fruit, or allulose. Powdered sweeteners mix better and won’t leave a gritty texture in your creamy filling.
• Add cocoa powder on top. Dust the top with unsweetened cocoa powder right before serving. It adds a nice chocolate flavor and makes your tiramisu look extra pretty, just like the traditional version.
• Make it ahead of time. Keto tiramisu actually tastes even better the next day. Making it ahead lets the coffee and cream flavors really soak into the cake layers. It’s a great make-ahead low carb dessert for holidays, birthdays, or just because!

Storing Ideas

• Fridge – Store your keto tiramisu in an airtight container in the fridge. It will stay fresh and delicious for up to 5 days. Just make sure it’s covered well so it doesn’t dry out or absorb any fridge smells.
• Freezer – Want to save some for later? You can absolutely freeze tiramisu! Place any leftovers in a freezer-safe container or wrap individual slices tightly with plastic wrap and foil. Freeze for up to 2 months.
  When you’re ready to enjoy it, just thaw it in the fridge overnight. The texture may be slightly softer after freezing, but it will still taste amazing.
