A super easy keto tiramisu cake filled with coffee and whipped cream is the perfect make-ahead low-carb keto delicious dessert.
This low-carb version is only 3.1g net carbs per slice and is perfect to enjoy on your keto diet.
You can make this as boozy as you like. Alternatively, you can omit the alcohol entirely, especially when serving children. Or, why not simply drizzle a little brandy over the top of individual servings for those who like it? No matter what, you'll love this low-carb keto tiramisu.
What is keto tiramisu?
Tiramisu generally starts with a dry sponge, sponge fingers, ladyfingers, or two-day-old sponge cake. If the sponge is dry, it allows the coffee and brandy liquid to be soaked up without going soggy.
I made a quick flourless sponge and cooked it for a little longer to allow it to dry out quickly. I didn't want to wait for two days to complete the recipe. Who does? The result was a delicious keto tiramisu.
If you enjoy classic tiramisu, you will enjoy this low-carb keto version. This keto tiramisu recipe is just as rich and delicious, and you can eat it on the keto diet.
You can adapt the recipe by adjusting how strong you brew your coffee (I like mine strong) and how much brandy you add. You can even make this alcohol-free by using brandy essence.
Ingredients for tiramisu layers
This keto tiramisu recipe may taste fancy, but it's quite simple to make. All my healthy recipes are sugar-free, gluten-free, and low in net carbs,
These are the ingredients you need to make tiramisu:
Flourless keto pound cake (sponge)
- Butter - use salted butter or unsalted butter and add a pinch of salt to taste.
- Coconut flour - do not confuse this low-carb flour with almond flour, they cannot be swapped in this keto recipe.
- Granulated sweetener of choice - the most popular low-carb keto sweeteners are erythritol, xylitol, allulose, or monk fruit.
- Vanilla extract - or vanilla essence, buy the best variety you can afford. You can taste the difference!
- Baking powder - do not confuse this with baking soda.
- Eggs - fresh eggs at room temperature are best.
Tiramisu coffee mixture
- Strong coffee - you can use freshly brewed espresso or instant espresso coffee powder.
- Brandy - you can omit this altogether, or opt to use an alcohol-free brandy essence.
Tiramisu cream filling
- Heavy whipping cream - heavy cream or double cream
- Granulated sweetener of choice - use your favourite powdered sweetener
- Brandy - again, you can omit or use brandy essence to make an alcohol-free tiramisu dessert.
- 90% dark chocolate - or melted sugar-free chocolate chips.
For complete instructions and amounts, see the keto tiramisu recipe card below.
This is my flourless sponge (pound cake) which I slightly overcooked to ensure it was dry enough for the keto tiramisu recipe. I adapted the recipe from my flourless berry sponge cake, just omitting the berries.
The flourless sponge is such an adaptable recipe, and I am sure it will feature in many more sugar-free and low-carb recipes in the future. It's the perfect blank slate!
1: Make the keto tiramisu cake
Mix the melted butter, coconut flour, sweetener, vanilla, and baking powder together until smooth. Add the eggs and make sure it is completely combined.
Some recipes call for egg yolks or egg whites only, but I use the entire eggs.
You can mix the ingredients using an electric mixer or use a rubber spatula to gently fold everything together.
Pour the batter into a prepared pan that has been lined with baking parchment paper, and bake until it is completely cooked in the center and golden brown.
Remove the pound cake from the baking pan and allow it to cool completely on a wire wrack.
After it is completely cooled down, cut it in half and let it dry out for a few hours to ensure it dries as much as possible.
2: Make the tiramisu coffee mixture
Combine coffee and brandy together. Then, drizzle it on top of the dried sponge slices. Pour slowly to give the sponge enough time to soak up the coffee flavor.
3: Make the tiramisu cream filling
For an easy keto tiramisu, I did not use mascarpone cheese or cream cheese. I make it simple by using a combination of heavy whipping cream, brandy, and a sweetener (or sugar alcohol).
Whip these three ingredients together until it is firm and stiff peaks form.
4: Assemble the tiramisu
Place half of the coffee-drizzled sponge slices in the bottom of a serving dish.
Spread half of the cream filling mixture on top.
Add the other half of the keto sponge cake on top, and then spread more of the whipped cream.
To decorate a tiramisu cake, melt some dark chocolate or sugar-free chocolate chips in a small bowl using the microwave or a double boiler.
Drizzle the melted chocolate on top of this classic dessert.
Store this keto tiramisu cake in the refrigerator for up to three days in an airtight container. Or keep it in the serving dish covered with a lid or aluminum foil so that it lasts longer.
You don't have to make your own whipped cream, you can buy store-bought sugar-free whipped cream topping.
Instead of coffee, use espresso in the coffee mixture for this low-carb tiramisu recipe.
Finally, you can use cream cheese instead of the heavy whipping cream, but it will make the cake denser.
- Try cocoa powder. I did not use cocoa powder in my recipe, but you can add a little bit into the sponge cake layer if you want to make chocolate layers. You may need to add extra liquid.
- Make it into a party-ready dessert. If you want to make this keto recipe for a party, I suggest creating your layers inside small ramekins or mason jars. Now you will have single-serving desserts for your guests.

Yes, this keto recipe tastes even better the next day. Keep it covered in the refrigerator for the best results.
Instead of a traditional mascarpone mixture such as mascarpone custard, I used a combination of heavy cream and powdered sweetener. It has the same rich flavor and smooth texture. Plus, those two ingredients are easier to find in the store.
Traditional tiramisu is not good for weight loss. It is calorie-dense and high in carbs. My recipe is low-carb, sugar-free, and gluten-free which are more appropriate for a low-carb diet or keto diet.
Yes, you can use brandy extract, rum extract, or rum flavoring to give a traditional rum flavor but without alcohol. You can add these to the coffee layer, and even some coffee extract to make it taste absolutely delicious.
No, instead of a custard layer, mascarpone filling, or a cream cheese layer, you use whipped heavy cream and gently fold powdered sweetener and vanilla, even cocoa powder if you wish.
No, you cannot swap almond flour in this low-carb keto recipe. These two low-carb flours behave totally differently from one another.
The traditional recipe is a classic Italian dessert layered with espresso-soaked biscuits, sponge slices, lady fingers, mascarpone filling, and whipped heavy cream. This delicious dessert is covered with a dusting of cocoa powder.
Yes, freeze in an airtight container for up to 3 months.
This may be because you didn't bake the sponge (pound cake) for long enough. The sponge needs to be dry enough to soak up the coffee mixture.
