Looking for a way to enjoy a classic dessert on your keto diet? Well, then this keto-friendly tiramisu cake is a must-try. No need to feel deprived while on a keto diet with a delicious recipe like this.
It’s the ultimate low-carb tiramisu cake recipe, the perfect make-ahead keto dessert.
Like most recipes I convert to be low-carb keto-friendly, they start with a craving. This keto tiramisu was no exception. In fact, I had been desiring a tiramisu dessert for a while now. Not willing to succumb to temptation, a healthy option needed to be birthed.
Tiramisu is by far one of Italy’s finest desserts. If you are wondering what is exactly is a tiramisu, it’s a dessert that has layers of espresso-soaked biscuits that are sandwiched with a layer of creamy mascarpone filling and then topped with a generous dusting of cocoa powder.
Is it any wonder that this dessert was a favorite of mine prior to going keto? I knew it would only be a matter of time before I would create a keto tiramisu cake recipe.
This recipe follows the basic concepts of a traditional tiramisu, except this is a much healthier option. Why? because although tiramisu isn’t keto, it can be by replacing the ladyfingers with pound cake, and make our homemade sugar-free filling.
I also have keto tiramisu cheesecake (no-bake) that is a delicious breeze to make that you should also try.
In fact, I have a complete list of Keto Cakes that as a fan of cakes I encourage you to also visit.
Keto Tiramisu Cake
Leave it to the amazing keto community to come up with several low-carb tiramisu recipes. I am quite certain that I would have thoroughly enjoyed any number of them.
However, this girl had to try her hand at converting this Italian favorite too and come up with a keto tiramisu recipe for you all to enjoy. I can’t wait for you to try my rendition of this recipe.
With that being said, my keto tiramisu will require a few more steps, but I assure you that it will be worth the little extra effort. This low-carb version has all the elements of making tiramisu, with a few of my hacks to keep things easier.
Trying to keep things simple I decided not to make low-carb ladyfingers. Although a true classic tiramisu dessert starts with either a very dry sponge cake or ladyfingers, this would require more work.
I thought of using my keto cream cheese pound cake to take the place of the lady fingers. In order to create the classic-looking shape of tiramisu, I baked my pound cake in a flat jelly roll pan and then sliced the cake to look like ladyfingers.
This proved to be the perfect solution. By using my trusty keto pound cake recipe as the base I was able to save lots of time and effort.
I use almond flour for this recipe. However, if you need a coconut flour option you can use our keto coconut flour pound cake recipe instead.

Keto Cake Layers
- Almond flour measured and sifted
- baking powder
- Granulated sugar-substitute, Lakanto Monk fruit
- Eggs, room temperature
- Full-fat cream cheese, room temperature
- Room temperature softened butter
- Vanilla extract
- Egg yolks, room temperature

- Mascarpone cheese or a combination of 8 ounces of cream cheese and 1/2 cup sour cream to take the place of mascarpone cheese
- Heavy cream
- Espresso coffee or strong coffee

Cocoa topping & bottom layer
This recipe makes two 9×5 inch tiramisu cakes or one large 9×13 dessert, making it perfect for the holidays.
The signature flavor in tiramisu is strong coffee. It’s why I like using espresso but if that’s not possible then using a strongly brewed coffee is the next best thing.
This recipe calls for rum or rum extract to give the tiramisu an authentic flavor. The dusting of cocoa powder is key in creating as close of a recipe as to its high carb counterpart.
If you live in an area that you cannot source mascarpone cheese easily, I have added instructions for using cream cheese and sour cream that not only works well but is more economical.
- Use only room temperature eggs, butter, and cream cheese The number one thing to remember when making both the cake and the filling is to start with room temperature ingredients. This is important so that the cake batter beats evenly and when making the filling that the cold egg yolks do not cause temperature shock.
- Make the filling in a double boiler Note that the custard filling will need to be made in a double boiler that is set to low heat so that the yolks do not overcook and curdle. You can make your own double boiler by placing a large bowl over simmering water. Just be sure not to allow the water to touch the bottom of the bowl since you are cooking with steam and not direct heat.
- Once the keto sabayon filling is made, you will need to beat cold heavy cream until medium peaks are formed and then fold into the filling.
Best Sugar-Substitute For A Keto-Friendly Tiramisu Cake
Traditional tiramisu is NOT keto-friendly. But that does not mean we can’t enjoy a keto tiramisu that we have made low in carbs by replacing the ladyfingers with a low carb pound cake and by swapping regular sugar for keto-friendly sugar substitutes.
The following are my sweetener recommendations:
My number one choice is Lakanto Monk Fruit and it’s what I used in this recipe. This is because the texture and flavor are what I have found to be the closest to real sugar.
Having said that, I’m also a fan of the Swerve brand of granulated sugar substitute, which is an erythritol blend. Similar to Lakanto it uses sugar alcohols and has a 0 % impact on blood sugar.
Personally, I don’t like using stevia because I am sensitive to the aftertaste. But if that’s not the case for you, you could certainly use the stevia and erythritol-based brand Pyure for this recipe.
However, if you go this route, you will want to use 1/2 the amount called for in this recipe since it’s much sweeter.
Lastly, if you can’t easily find a more natural sugar substitute you can also use Splenda with great success.
