This Keto Tiramisu recipe is LEGIT! Made from my keto ladyfingers and a proper sabayon with mascarpone, you'd never be able to tell it's low carb!
A batch of homemade Keto Marinara Sauce ended up leading to making Keto Chicken Parmesan, Keto Spaghetti and Meatballs, and Keto Mozzarella Sticks.
Traditional tiramisu - a classic Italian dessert - was always my go- to when going to Italian restaurants in my pre-keto diet, pre-gluten allergy days.
Layers of espresso soaked lady finger biscuits, topped with layers of a silky smooth mascarpone cream filling? There’s a reason it’s such a classic dessert.
Unfortunately, the traditional recipe for this delicious dessert is full of high-carb ingredients.
Clearly, I was going to need to design a keto version, suitable for those on a low carb diet.
The first step was developing a proper Keto LadyFingers recipe as the base, and it was smooth sailing from there.
This is an excellent dessert - you’d never know it was “diet food” for anyone on a low-carb diet. My non-keto husband hoovered it like it was the real thing!
It’s absolutely convincing as an authentic tiramisu, and - even with making the ladyfingers from scratch - it’s a relatively easy tiramisu recipe. No special skills or equipment needed!
A Note on the Nutritional Information
The software we use doesn’t post the sugar alcohol content to the public-facing recipe card, but I can see that info in the backend.
So for those tracking such things, 31 grams of carbs per serving comes from sugar alcohols, assuming you use the entire batch of lady fingers (You probably won't).
So, once you subtract that and the fiber, this comes out to 4 grams of net carbs per serving.
(That's also assuming a serving is 1/9th of the recipe. It's very rich, and that's a HUGE serving, IMHO!)
Ingredients
Keto Lady Fingers
This delicious recipe for homemade tiramisu uses my Keto LadyFingers as the low-carb cake layer.
The ingredients for that recipe include:
Super Fine Almond Flour
Unflavoured Whey Protein Powder
Coconut Flour
Sugar substitute - I use an Erythriitol / Monk Fruit Blend
Large eggs
Xanthan Gum
Vanilla Extract
Salt
It’s a really simple recipe, but I recommend making it the day before, to let the cookies dry out a little before using them in this low carb tiramisu recipe.
Remaining Ingredients
In order to turn those lady fingers into a classic tiramisu, you’ll also need the following ingredients:
Mascarpone cheese
Heavy whipping cream
Sugar substitute - I use an Sugar substitute - I use an Erythriitol / Monk Fruit Blend
Large egg yolks
Cold espresso / Strong coffee
Rum - We use Screech
Unsweetened cocoa powder
How to Make Keto Tiramisu
The actual recipe is in the recipe card at the end of this post. This is a pictorial overview with additional tips and information
Make the Creamy Filling
Measure your erythritol into a food processor, blitz for a few seconds until it’s a finer grind. You don’t need it to be powdered, but a finer grind helps ensure a creamy mascarpone filling.
Set up a double boiler - either an actual set, or a small pot with a glass or metal bowl that will nest in it, like pictured. Put a couple inches of water into the pot, and ensure that the bottom of the bowl is about an inch above that water level.
Get the water boiling.
In the top pot/bowl, whisk together your sugar substitute and egg yolks until well combined. Set the smaller pot / bowl on top of the pot of boiling water. Cook the egg yolk mixture, whisking constantly, for about 10 minutes.
Expect that it will thicken up, increase in volume, and lighten in colour as it cooks.
Remove pot of egg mixture from the double boiler, continue whipping for a minute or so.
Allow to cool for 5 minutes or so - it doesn’t have to come all the way to room temperature.
Add the Mascarpone to your cooked egg mixture, whisk JUST until combined. You don’t want to overbeat this, or your filling could curdle.
Again, don’t over beat this, or you’ll end up with butter.
Add the mascarpone mix to the large bowl of whipped cream, and very gently fold together just until combined. Set this cream mixture aside.
Assemble the Tiramisu
Pour espresso and rum into a smallish bowl, mix to combine.
Quickly dip ladyfingers in the coffee mixture - really just a quick dunk, so they don’t get soggy - and arrange in 2 rows in an 8" x 8" square baking pan.
Don’t worry - a quick dunk is all you need to get a good amount of coffee flavor into the dessert!
Spoon half of the tiramisu cream over the layer of lady fingers, spreading to form an even layer.
Repeat with a second layer of dipper lady fingers and the remaining filling.
Cover with plastic wrap and chill for at least 2 hours (for best results, 4-6 hours).
Just before serving, use a fine wire sieve to give the top of the pan a dusting of cocoa powder.
Keto Tiramisu Variations
Want to change it up a bit? Here are some ways to customize this recipe.
- Rather than making this in a pan, you can make it in individual cups. (Just break the ladyfingers up to fit!)
- Add some vanilla extract or rum extract to the mascarpone cream.
- Swap out the rum for some sugar free coffee liqueur ... or Keto Irish Cream!
- Add a layer of strawberry slices or fresh raspberries.
- Add a bit of fine lemon or orange zest to the egg yolk mixture before cooking. You can even add a splash of lemon juice to it as well.
