Sugar Free Tiramisu (Low Carb & Delicious!)

I’M SO SORRY! I really don’t know why it’s taken me so long to share this sugar free tiramisu recipe with ya’ll. Especially since its one that I’m so proud of!

I came up with this recipe in 2020 when I had my keto baking business and it was one of, if not THE most popular item on the menu!

There were people ordering this thing multiple times a week. So I’m not the only one in love with it. This recipe was tested and retested until I came up with something that was truly restaurant quality without the sugar.

Crisp homemade ladyfingers, creamy mascarpone, and the intoxicating aroma of dark coffee running throughout.

This tiramisu isn’t just “good for being sugar free” its good PERIOD

Ingredients Needed For Sugar Free Tiramisu

Almond Flour – Adds a subtle nutty flavor to our ladyfingers and keeps the carb count low

Coconut Flour – Coconut Flour is super absorbent. This is going to help dry out our ladyfingers so they can hold more coffee! More coffee = Better tiramisu

Protein Powder (Whey Isolate) – The protein powder helps the cookies maintain their shape and gives the ladyfingers a better flavor

Cinnamon – Just a pinch gives a nice flavor to our homemade ladyfingers

Baking Powder – To help our ladyfingers rise when baked

Kosher Salt – enhances the flavors

Egg Whites – The meringue base for our ladyfingers will help the cookies maintain their shape within the tiramisu

Egg Yolks – Add a lovely rich flavor to our mascarpone cream, similar to French vanilla ice cream!

Powdered Monk Fruit – We want a powdered monk fruit sweetener for our cream because it will dissolve much better than granulated

Lakanto Baking Sweetener – This is my favorite sugar free sweetener for making meringue! I highly recommend using if you can find it

Mascarpone – This is the delicious creamy cheese used in tiramisu

Heavy Cream – Helps lighten the mascarpone cream

Vanilla Extract – adds a lovely vanilla flavor to the cream and homemade ladyfingers

Dutch Cocoa – Tiramisu just isn’t tiramisu without a generous dusting of unsweetened cocoa

Instant Espresso – This is optional but it adds an extra kick to the cocoa powder

Coffee / Espresso (Chilled) – For soaking the ladyfingers

Tips For Making Sugar Free Tiramisu

The Lady Fingers

Use the recommended sweetener. I prefer the Lakanto brand baking sweetener (in a purple bag). It has a similar sweetness level to sugar and dissolves nicely. I prefer this over the powdered monk fruit because you can use more without it being overly sweet. You also get more cookies out of the recipe this way due to more volume

Piping Tip – Make sure you use a round piping tip to make these cookies. I used a Wilton #1A tip Without a piping tip your cookies will have no shape. They’ll still taste good though!

Soaking The Ladyfingers – Don’t be afraid to REALLY soak your ladyfingers. They can hold more coffee than you think. I suggest test soaking 1 or two and tasting them to see how long they need.

I soak between 25-30 seconds each!

Sabayon (Hot egg yolk mixture) – Make sure to gently heat your egg yolks and powdered sweetener over a double boiler so the eggs don’t scramble.

Whisk the yolks until they’re thicker and pale in color. I cook mine until the eggs feel pretty hot, then finish whisking them off the heat until thickened

Allow the Sabayon (Egg yolk mixture) to cool a bit before mixing with mascarpone. Warm to the touch is fine but it should NOT be hot when you add it to the mascarpone!

Coffee / Espresso – Make sure your coffee or espresso is chilled before dunking the ladyfingers. If its too hot the ladyfingers will start to dissolve

Assembling Tiramisu (Sugar Free)

8×8 Baking Dish – The perfect size for a tiramisu but if you want a taller one assemble in a loaf pan instead

First Layer – Soak ladyfingers and place on bottom of baking dish. I can fit 8-10

Second Layer – Half the mascarpone cream

Third Layer – Dust with cocoa.

REPEAT!

Ladyfingers – I can usually fit more on the second layer

Mascarpone Cream – add remaining half of cream

Cocoa – Dust the top generously with cocoa.

Wrap and Chill tiramisu in the fridge for 4 hours, or overnight

Sugar Free Tiramisu F.A.Q.

Where can I buy Lakanto baking sweetener? You can find it in the baking section at your local sprouts. You may also find it in the specialty foods section at discount stores like Marshalls and TJ Maxx

Can I use cream cheese instead of mascarpone? I don’t recommend subbing cream cheese for mascarpone. Your tiramisu will end up too thick and tangy instead of lightly creamy and custard like.

Where can I find mascarpone? You can find mascarpone in the specialty cheese section of the grocery store. Usually near the deli area

How to store tiramisu? You want to store tiramisu in the fridge either wrapped in plastic or covered with a tight fitting lid.

Can tiramisu be frozen? Surprisingly tiramisu freezes very well! Just make sure to freeze it in individual portions in covered containers.

What should I do with the extra ladyfingers? I like to freeze them and keep them on hand for my next tiramisu!

How should I use the extra egg whites? You can add the extra egg whites to your omelets or freeze them for other baking projects.
