This keto tiramisu recipe will have you coming back for more. Tender almond flour cake layers brushed with coffee and layered with a creamy sugar-free mascarpone filling. It’s an easy low carb version of the Italian classic dessert.
My keto tiramisu gets a much deserved update. This beloved Italian dessert now has fewer carbs and is even easier to make. It’s one of my favorite keto desserts and it may just become one of yours too.
Now, when I call this recipe “easy, I have to acknowledge that it’s all relative. Perhaps I should say that it’s easier keto tiramisu. Because authentic tiramisu actually takes some effort to make.
And the keto version takes even more effort to make, since we can’t just head to the store and grab a package of pre-made lady fingers. Trust me, I know of what I speak. I created a true-to-the original for The Ultimate Guide to Keto Baking, even going as far as making my own homemade lady fingers.
While it was delicious, it was definitely more work than many people want to put in. So how can you simplify the process and still be able to enjoy all the delicious flavors of the Italian classic in a way that won’t blow your low carb diet? Read on!
Easy Pound Cake Keto Tiramisu
Making your own keto pound cake is a whole lot easier than making your own keto lady fingers, and it makes a perfect replacement for the spongy cookies.
I had seen some conventional versions using pound cake, like this one from Feast and Farm. Once it’s brushed with coffee and layered with mascarpone, you can hardly tell the difference in taste or in appearance. It’s really just about providing the dessert some structure for the layers.
When I first wrote this keto tiramisu recipe, I went to the trouble of making pound cake in a loaf pan, waiting for it to cool, and slicing it thinly. But then it hit me… why not bake it as a sheet cake? That way, it bakes in less than half the time and I could cut the layers easily to fit my pan.
I also simplified the tiramisu cream, forgoing the traditional method of making zabaglione first. Zabaglione is a creamy concoction made by whisking egg yolks over gentle heat with sugar, and often with a little sweet wine, like marsala. All very tasty but yet another time consuming process that many people don’t have time for.
You can get the same delicious tiramisu flavors simply by folding the mascarpone and whipped cream together. Not quite authentic but it definitely serves the purpose!
Tips for Easy Keto Tiramisu
The cake
You will want to make this first so that it can cool as you prepare the filling. This is a cake made with both almond and coconut flour, as I like that consistency the best. However, if you would like to make it with just almond flour, you can follow the ingredients in this Keto Victoria Sponge Cake. The baking time will be about the same.
I baked it in a 15×11 inch jelly roll pan, which allowed me to get thin layers of cake with very little wasted. However, if you only have a half sheet (18×13), you can bake it in that. Just know that your cake layers will be thinner and the cake will bake faster so keep your eye on it. You will have a bit of cake leftover after creating your layers.
The coffee syrup
This isn’t really a syrup so much as a combination of espresso and rum. You don’t have to use the rum but it won’t be tiramisu if you don’t use the coffee! It’s easier to brush this over the cake, rather than dipping the cake into it, as you would for lady fingers. But the end result is about the same.
The tiramisu cream
Now for the delicious part! Because anything made with mascarpone has to be delicious. I recommend beating the mascarpone to a smooth consistency before adding the other ingredients. Make sure it’s at room temperature before proceeding so that it doesn’t clump or curdle.
Whipping the cream separately and folding the two parts together creates a light and voluminous filling.
The garnish
The final step involves dusting the top of the dessert with a coating of cocoa powder and shaved chocolate. You can use either ChocZero or Lily’s for the chocolate and it takes only about half an ounce to get lovely little chocolate flakes overtop.
Can you make Keto Tiramisu ahead?
Absolutely! This easy tiramisu recipe has no eggs so as long as your mascarpone and cream are fresh, it will be fine for up to a week in the fridge. As with any dessert recipe, wrap it up tightly.
It can also be stored in the freezer for up to two months.

Easy Keto Tiramisu
Ingredients
Cake Layers
- 2 cups almond flour
- ⅔ cup Swerve Granular
- ⅓ cup coconut flour
- ⅓ cup unflavored whey protein powder (or egg white protein powder)
- 1 tablespoon baking powder
- ¼ teaspoon salt
- 3 large eggs
- ⅔ cup water
- ½ cup butter, melted
- 1 teaspoon vanilla extract
Coffee Syrup
- ½ cup espresso or strongly brewed coffee
- 2 tablespoon dark rum
Tiramisu Filling
- 16 ounces mascarpone, softened
- ¾ cup powdered Swerve Sweetener divided
- ¾ cup heavy whipping cream
- ¾ teaspoon vanilla extract
Garnish
- 1 tablespoon cocoa powder
- ½ ounce sugar-free dark chocolate
Instructions
Cake Layers
- Preheat the oven to 325F and grease a rimmed 15x11 inch rimmed sheet pan. Line the bottom of the pan with parchment and grease the parchment.
- In a large bowl, whisk together the almond flour, sweetener, coconut flour, protein powder, baking powder, and salt. Stir in the eggs, water, butter, and vanilla extract until well combined and smooth.
- Spread the batter evenly in the prepared pan and bake 18 to 22 minutes, until the edges are golden brown and the top is just firm to the touch.
- Remove and let cool completely in the pan.
Coffee Syrup
- In a small bowl, whisk together the coffee and the rum. Set aside.
Tiramisu Filling
- In a large bowl, beat the mascarpone until smooth, then beat in ½ cup of the sweetener. Add 3 tablespoons of the coffee/rum mixture and beat until well combined.
- In another large bowl, beat the cream with the remaining sweetener and the vanilla extract until it holds medium soft peaks (the top of the peak should fall over when the beaters are lifted).
- Gently fold the whipped cream into the mascarpone mixture until well combined.
To Assemble
- Cut the cake into pieces to fit into the bottom a 9x9 inch pan. Brush with half of the remaining coffee mixutre. Spread half of the mascarpone mixture over top.
- Repeat with remaining cake, coffee mixture, and mascarpone mixture. You will have a few bits of cake left over. Discard or use for snacking!
- Dust the top of the tiramisu with cocoa powder and grate the chocolate over top. Refrigerate 2 hours to firm up before cutting.

I had to tell you that I made this for the 2nd time last nite. It was a disaster! I ended up with cake in tiramisu flavored sauce. Not that the recipe is bad but I think the brand of marscapone I bought was way to thin, it was cheap and I had never seen that brand before. We laughingly christened it “Tiramisu Soup”.
It made me think though. If I use the cake and soak it in sherry and add strawberries and an artificially sweetened boiled custard. Voila! Sherry trifle… Haven’t had a good one in years!
Dee says
I made this Saturday night and I must say, this is the best low carb dessert I have made to date! I have never posted before because I have always been disappointed! Someone recommend your site and I am in low carb heaven!!! Thank you so much!!!
Carolyn says
That’s wonderful to hear, Dee!
Julie says
Thank you so much for this recipe. I did not bring down the cream or marscapone to room temperature and did not have any trouble with separation. Just added everything very slowly. So very easy to make, this will be our new go to special occasion recipe. It is the morning after Thanksgiving and this is the leftover I am craving. Thanks again for all your efforts with low carb baking. It is great to be able to bake again!
Carolyn says
I think it must be the Trader Joe’s mascarpone, then. It separates on me almost every time!
Leigh says
I am in love… this looks so amazing and I WILL be eating this by tomorrow… big thanks for sharing and all the goodies on your blog!
Melanie says
It looks like you used a 9×13 glass dish in the pictures. Is that really an 11×17 inch pan like you called for?
Carolyn says
Yup! Trust me, I wouldn’t give a pan size that wasn’t what I used. I remember cutting up the pound cake in this recipe and trying to get it to be enough for my 9×13 and it just wasn’t right. You *might* be able to to do 9×13 if you can cut the pound cake more thinly,though.
Julie says
This dessert was a huge hit for Thanksgiving, and the high carb pumpkin pie was ignored by the kids who typically don’t like low carb things. But there is no way I could have used an 11×17 pan, (are those actually a thing?), and used an 11×7 instead. That left me with two left over slices and some cream to put together a sample serving to reward the cook without cutting into the pretty tiramisu. Absolutely orgasmic!
Carolyn says
Yup, 11×7 is actually a real size! I thought 9×13 was too big and 9×9 too small so I used my 11×7 glass baking pan.
Julie says
You have a typo in your recipe then, which calls for an 11 x seventeen pan….unless my eyes are totally shot and I am just seeing things!
Carolyn says
Oops! Thanks, I just fixed it.
Lorraine says
Finally got a chance to make this yesterday and it was amazing! Even though I messed up! My husband’s brother and his wife were in town and arrived 2 hours early so I was quite distracted and forgot to add the cream, even though it was sitting right there on the counter. I noticed right when I turned from putting the completed dessert in the fridge! I’m sure the look on my face was classic, if anyone had been watching. The good news is that it was fantastic anyway so no one noticed. Even my daughter, who is not a fan of my low carb baking, thought it was great.
I used a smaller pan and 12 slices of cake and it worked just fine. I look forward to trying it again, this time with the cream LOL!
Oh, and it was even better today.
Carolyn says
So glad it still worked out!
hilary says
Home made marscapone! I need to be making that right now, THANK YOU, I never realised it was so easy.
Kami says
Okay, wow. This was incredible! Thank you so much for sharing! I added a little extra coffee (because that is my favorite part), but I was so excited to have a GF baked recipe finally turn out to be scrumptious! I think when I make it in the future, I will bake the pound cake in two layers (like a layer cake for a birthday). I might have done it wrong, but when I sliced up my pound cake to line the pan, it got really crumbly. Just another idea! Thanks again! 😀
CATRIONA says
Tiramisú has always been my favourite desssert. Thank you so much for helping me bring it back into my life! It was an utter joy being able to taste it again 🙂
janet says
Finally got around to making this last week, it helped that the marscapone was on bogo at the market. Made the cake the day before and put it together for dinner on Tuesday. My hubby just about had a spiritual experience when I served it. He said it was fabulous and to put on the regular lists, maybe once a week. I don’t know if I’ll be able to manage it that often, but this is the second of your dessert recipes that have become a favorite with us. (Blueberry Eton Mess is the other)
Thanks for the hard work and keep on baking, cause we love it!
Carolyn says
Wonderful! Glad you found the mascarpone on sale like that. It can be pricy!
Cici says
I’m visiting my mother & brought with me my “GF” baking bag so that I can make delicious LC GF desserts exactly like this one! I somehow have managed to leave my liquid stevia at home. How much more swerve should I substitute for the 20 drops in the butter cake?
Carolyn says
Probably about 1/4 cup.
dina says
it looks delicious!
Veena Ramachandran says
This turned out to be one of the best desserts I have ever made!!! ABSOLUTELY loved it, Carolyn! Thank you for creating such wonderful beauties that we can all hog on completely guilt-free! You’re extremely talented. : )
Carolyn says
Thank you, Veena! So glad you liked it!!!
Veena Ramachandran says
Hi there!
Thank you for being so creative with all your recipe ideas. I have such a sweet tooth but being a victim of hypothyroidism, I have the strongest inclination towards weight gain! That’s when all day I dream about food came to my rescue! Haha.. : D
Anyhow, I’m getting started with this recipe. However, it’s my first time working with mascarpone cheese. Could you tell me for how long approximately I’d need to leave the cheese outside the refrigerator to get it to room temperature?
Thank you! : )
Carolyn says
A few hours should be sufficient.
Cali says
I do not use sweeteners. What would be the equivalent amount of sugar to add. Also, I do not do well with whey powder. Can I omit this or do I need to use a substitute?
Carolyn says
You can use sugar in the same amounts I used Swerve. You do need some sort of powdered, dry protein to help the cake rise properly and hold its shape. You could use hemp protein or even powdered egg whites.
Rene Hughes says
Guess what I am making for my 4th of July weekend?! 🙂
lcPanama says
This is my first comment on a blog ever. I had to comment on this recipe. Low Carb baking is often disappointing (at least for me), but this recipe is absolutely perfect!! Seriously PERFECT! Creamy, rich, moist, just the perfect coffee flavor, not too sweet but it definitely satisfied my sweet tooth. Probably the only cake I’ll eat from now on. Thank you so much Carolyn.
I used truvia baking blend instead of swerve (that’s what I had) and it worked just fine. I used a blendtec to powdered it for the mascarpone mixture.
I made this cake last night and refrigerated over night. I let it warmed up a bit before serving it to allow the cream to soften again :D. Soooo Good!
Thank You!!!
Carolyn says
That is just wonderful to hear. I am so happy you liked it!
heatherstanley says

Lorraine says
Wow! I’m still basking in the afterglow of the Chocolate Covered Strawberry Cheesecake and now you post this! Definitely next on the list!
Stefanie says
Me, too! My boyfriend and I are still working on that strawberry cheesecake… gotta finish that before we can try another fun dessert! This is on the list, though!
Cookin Canuck says
Did someone just put pound cake and tiramisu in the same sentence? Yep, you have my attention! This looks absolutely fantastic, Carolyn!
