A Keto Tiramisu Recipe That Tastes Like the Real Thing!

Why You’ll Love This Keto Tiramisu

The Secret to a Perfect Keto Sponge Cake

A great tiramisu starts with a light and spongy base. Since store-bought ladyfingers are high in carbs, this recipe replaces them with a homemade almond flour sponge cake. The combination of whipped egg whites and almond flour ensures a soft, delicate texture that soaks up the coffee mixture beautifully. Bake it in these heart-shaped baking pans for the cutest results.

How to Make Keto Tiramisu

Prepare the Coffee Mixture – Dissolve the espresso powder in hot water. Set aside to cool.
Make the Keto Sponge Cake – The batter is made by mixing egg yolks, almond flour, baking powder, avocado oil, and almond milk. Beating egg whites separately with cream of tartar ensures the sponge remains light and airy. Once combined, the batter is baked until golden.
Whip Up the Mascarpone Cream – Blend mascarpone (or cream cheese), powdered erythritol, vanilla, and rum extract (if using). Whip heavy cream separately, then fold it into the mascarpone mixture for an ultra-smooth, airy texture.
Assemble the Tiramisu – Layer the keto sponge cake with the coffee mixture, followed by the mascarpone filling. Repeat layers until the dish is full.
Dust with Cocoa Powder – The final touch is a generous dusting of unsweetened cocoa powder for that classic tiramisu finish.
Chill and Enjoy – Let the tiramisu rest in the fridge for at least 4 hours (preferably overnight) to allow the flavors to meld together beautifully.

Pro Tips for the Best Keto Tiramisu

Chill the tiramisu overnight for the best texture and flavor.
Use high-quality espresso powder for a strong, authentic coffee flavor.
For extra richness, add a splash of coffee liqueur (a keto-friendly version) to the coffee mixture.
If you prefer a sweeter dessert, add a bit more erythritol to the mascarpone mixture.
