What Is Tiramisu?

Tiramisu is perhaps the most famous Italian dessert that has become famous worldwide. The original Tiramisu recipe calls for ladyfingers soaked in strong coffee, a fine and airy mascarpone cream made with sugar and eggs, and dusted abundantly with cocoa or coffee.

Is Tiramisu Keto-Friendly?

Traditional tiramisu is not keto-friendly because it’s made with ladyfingers, sugar, and other ingredients that are too high in carbs.

Fortunately, you can still enjoy tiramisu even if you are following a keto diet just by making a few changes to the ingredients. 

To make tiramisu keto, we’ll bake a cake layer made with almond flour and coconut flour to replace the ladyfingers.

Ingredients For Keto Tiramisu

Although it may seem a complicated recipe, you will be surprised to see that you will need a few easy ingredients that you probably already have in your kitchen. Here is a list with everything you will need:

For The Cake Layer

  • Almond Flour and Coconut Flour – these are my favorite flour substitutes I use in keto baking to get a super fluffy cake that’s not gritty or dry.
  • Sweetener – You can use any sweetener like Erythritol, Monk Fruit sweetener, or Allulose. These are the best choices because they don’t have any aftertaste and taste like sugar.
  • Baking Powder – helps the layer cake rise and become fluffy.
  • Eggs – use room temperature eggs to avoid that eggy taste and flavor.
  • Butter – use unsalted butter.
  • Almond Milk – adds moisture to the cake layer. You can also replace it with coconut milk.
  • Vanilla Extract – use the best quality vanilla extract that you can find.
  • Salt – to enhance the flavors.

For Mascarpone Filling

  • Mascarpone – make sure that it is softened to ensure good mixing.
  • Heavy Whipping Cream – makes the filling extra creamy.
  • Sweetener – use powdered sweetener to ensure that there are no visible lumps.
  • Vanilla Extract 

For Coffee Syrup

  • Espresso – Both cold brew and instant coffee are fine to use. You can make it decaf if you want or use hot chocolate instead.
  • Dark Rum – this ingredient is optional, but you can add it if you want to obtain that classic tiramisu flavor.

Frequently Asked Questions

Can I Use Cream Cheese Instead Of Mascarpone?

Sure, you will need 8 ounces of room temperature cream cheese, 1/4 cup heavy cream, and 2 tablespoons of butter to replace the mascarpone to make the filling for this recipe. However, you need to know that the original tiramisu is made with mascarpone that has a slightly sweet and soft taste, and if you use cream cheese, your tiramisu may taste more like a cheesecake.

Can I Make Tiramisu Ahead Of Time?

Sure, you can make this keto tiramisu ahead of time by preparing the cake layer in advance and storing it in the fridge. Then, make the mascarpone filling and assemble the cake for a few hours before enjoying it.

Is Mascarpone Keto?

I know you sprinkle the coffee rum syrup onto the baked cake but it doesn’t say this in your recipe. It’s in the oven now. I can’t wait for it to be done.
