Keto tiramisu is a low-carb version of the popular Italian dessert, made for people following a ketogenic diet. This dessert swaps out the usual high-carb ingredients for low-carb ones, making sure you still get the classic flavors of tiramisu-coffee-soaked cake, creamy mascarpone, and a dusting of cocoa-without giving up your diet goals. Done right, keto tiramisu tastes just as satisfying and rich as the original, giving you a sweet treat that sticks to low-carb rules.
What makes keto tiramisu special is how it replaces ingredients like sugar and regular flour with keto-friendly options. So, you can still enjoy this well-known dessert without the carbs. Thanks to smart ingredient choices, keto tiramisu can be just as delicious as the classic version, showing that low-carb desserts can taste great.
What is Keto Tiramisu?
Keto tiramisu is a sugar-free, low-carb, and many times gluten-free spin on traditional tiramisu (which means “pick-me-up” in Italian). Classic tiramisu is known for its layers: biscuits (usually ladyfingers) soaked in coffee, a layer of mascarpone cream, and a top coat of cocoa powder. In the keto version, these layers get reworked to have fewer carbs but keep the taste and texture that makes tiramisu so well-loved.
The idea is to make a dessert that feels and tastes like classic tiramisu, but without the sugar and high-carb cake. Regular sugar is switched out for keto sweeteners, and cake layers are made using almond flour, coconut flour, or other low-carb alternatives instead of wheat flour. The end result gives you all the flavors-espresso, mascarpone, and cocoa-that you expect, but lighter on carbs.
How does keto tiramisu differ from traditional tiramisu?
The main difference comes from the cake and the sweetener used. Classic tiramisu uses ladyfingers made with lots of sugar and white flour, dipped in coffee (sometimes with liqueur). The mascarpone filling typically uses egg yolks, sugar, and sometimes whipped eggs for a light filling.
Keto tiramisu changes these parts. Ladyfingers get replaced by a homemade cake made from almond or coconut flour (sometimes even a no-bake nut “cookie” as the base). Sugar is replaced by sweeteners like erythritol, monk fruit, or allulose. Some recipes still use a splash of rum for taste, but most stick to strong coffee or espresso to keep carbs low. The mascarpone mixture might be made simpler, often just with mascarpone and whipped cream for ease.
Is keto tiramisu low carb and gluten free?
Yes. Keto tiramisu is both low in carbs and gluten free. The focus of keto recipes is to cut out carbs, which means replacing the usual sugar and flour with things like almond flour or coconut flour and sweeteners. These swaps dramatically lower the carb count and make the dessert safe for people who can’t have gluten.
Using almond or coconut flour means there’s no wheat in the cake layer, so gluten isn’t a problem. This makes keto tiramisu a good choice for people with celiac disease or gluten intolerance, while still being enjoyable for anyone on a keto diet.
Ingredients for Keto Tiramisu
To get that real tiramisu taste without the carbs, it’s important to pick the right ingredients. Most changes involve using low-carb flours, sugar substitutes, and making some choices about dairy. The idea is to create a dessert that’s creamy, coffee-flavored, and rich, but without the sugar and extra carbs.
Best Sweeteners for Keto Tiramisu
Getting the sweetness right is important. Powdered sweeteners work best since they mix smoothly and don’t make the cream grainy. The top choices are:
- Erythritol (found in blends like Swerve or Lakanto): A sugar alcohol with almost no effect on blood sugar.
- Allulose: Melts easily and caramelizes like sugar, good for cakes and creams.
- Monk Fruit: Very sweet, usually mixed with erythritol for the right texture and bulk.
Keto-Friendly Cake Layers
Traditional ladyfingers are replaced with cake made from almond or coconut flour, or sometimes a quick nut and butter base. Almond flour cake is soft and soaks up coffee well, similar to ladyfingers. Coconut flour can be used as well, but it’s more absorbent, so you need less of it. Some recipes offer special keto ladyfinger recipes with whipped egg whites for a lighter texture, but a simple almond or coconut flour sponge works just as well for most.
Which Dairy to Use: Mascarpone, Cream Cheese, or Heavy Cream?
Mascarpone is the main dairy in tiramisu, giving the dessert its creamy texture. It’s best to make sure mascarpone is at room temperature before mixing. Some recipes add a bit of full-fat cream cheese for a thicker filling or to save money, just make sure it’s softened. Heavy cream is also used, whipped and folded into the mascarpone to keep the filling light and airy.
Flavor Add-Ins: Coffee, Cocoa, Spirits
Strong coffee or espresso is a must for the classic tiramisu flavor. Brewed coffee works if you don’t have espresso. This gets brushed onto the cake layers for a deep coffee taste. Cocoa powder is sprinkled on top, adding a bittersweet finish. Alcohol like rum or brandy is optional; if you use it, it should be in small amounts to keep carbs low, but you don’t need it for a great flavor.
How to Make Keto Tiramisu
The process for keto tiramisu is much like the original: bake or prep a cake layer, mix a strong coffee syrup, whip up a creamy mascarpone filling, and assemble everything in layers. After building the layers, the dessert is chilled so that the flavors blend and the mascarpone sets.
How to Make the Keto Cake Layer
You’ll usually bake a cake using almond flour, coconut flour, eggs, a keto sweetener, and melted butter. Spread the batter thinly on a baking sheet, bake for 18-22 minutes at 325°F, then let it cool and cut it to size for layering. If you want, you can use an almond-coconut flour blend for the best moisture and structure. For quick versions, some people use an “instant cookie” base made from nuts, butter, and coffee, which can be pressed into the dish without baking.
How to Make the Coffee Syrup
The syrup is made from strong espresso or coffee, with a little dark rum or rum extract if desired. Some people add a bit of sweetener to cut bitterness, but unsweetened coffee works well for a strong flavor. Brush this syrup onto the cooled cake pieces instead of dipping to avoid sogginess.
How to Make the Mascarpone Filling
Let mascarpone come to room temperature. Beat it with powdered sweetener until smooth. In another bowl, whip cold heavy cream to soft peaks, then fold it gently into the mascarpone mixture. This keeps the filling light. Some people add cream cheese or a splash of vanilla for extra richness or flavor.
How to Assemble Keto Tiramisu
- Prepare your pan. Lining it with parchment makes lifting easier.
- Lay the first layer of cake on the bottom.
- Brush with coffee syrup until covered but not soggy.
- Spread half the mascarpone filling evenly over the cake.
- Repeat with another layer of cake, more coffee syrup, and the rest of the cream.
- Chill at least 4-5 hours, or overnight, to set.
Finishing Touches
After chilling, dust the top with unsweetened cocoa powder. For extra chocolate, shave some sugar-free dark chocolate (like ChocZero or Lily’s) on top. You can add coffee beans as decoration if you like, but they are not usually meant to be eaten.
Tips for Keto Tiramisu Success
- Avoid soggy layers: Don’t over-soak the cake. Brush quickly rather than dipping.
- Prevent gritty cream: Always use powdered sweetener.
- Watch for split mascarpone: Don’t overmix. Use ingredients at room temperature.
- Fix crumbly cake: Don’t overbake, and pay attention to the almond-to-coconut flour ratio.
- Chill long enough: Give it time in the fridge for the best texture-at least four hours.
Storage and Make-Ahead Tips
- Refrigerator: Cover well with plastic wrap or use an airtight container. Keeps up to a week if no raw eggs are used.
- Freezer: Wrap tightly in plastic and then foil, or use a freezer container. Good for two months. Thaw in the fridge overnight before serving.
Popular Keto Tiramisu Variations
Keto tiramisu can be made in different ways to fit your needs or save time. Here are some favorites:
- Keto Tiramisu Mug Cake: Make a quick mug cake (from almond or coconut flour) in the microwave, layer with mascarpone cream, and top with coffee and cocoa. Great for single servings.
- Tiramisu Mousse: Whip mascarpone, cream, sweetener, and espresso, a layering with cocoa for a fast, no-cake dessert. Serve in glasses for easy portions.
- Single-Serve “Fat Bomb” Tiramisu: Assemble mini versions in jars, ramekins, or muffin molds, using a nut/butter base or small cake pieces. Good for meal prep or parties.
Coconut Flour vs. Almond Flour for Cake
| Flour | Texture | Notes |
|---|---|---|
| Almond Flour | Tender, moist | Absorbs coffee well, common in keto baking |
| Coconut Flour | Dense, crumbly | Use less than almond flour, good for nut-free need |
Adjust liquids and quantities depending on which you choose. Almond flour is more forgiving; coconut flour is good for those avoiding nuts, but needs careful measuring.

Common Keto Tiramisu Questions
Can you freeze keto tiramisu?
Yes! Wrap it well in plastic and foil or use an airtight freezer container. Freeze for up to two months. Thaw overnight in the fridge before serving. The texture may be a bit softer, but the taste stays good.
Do you have to use alcohol?
No. While classic tiramisu uses rum or wine for flavor, you can skip alcohol and still have great results. If you want the taste without the sugar, use a small amount of dark rum or extract-or just strong coffee.
Can keto tiramisu be nut-free or dairy-free?
Nut-free: Use coconut flour instead of almond flour, but adjust the liquid since coconut flour absorbs more. Dairy-free: Skipping dairy is tougher since mascarpone and cream are key parts. Some plant-based cheese or coconut cream can work, but the taste and texture will be different. It takes some experimenting to get right.
