Easy Keto Tiramisu recipe

The best thing about this keto tiramisu is how easy it is to make. Using the mug cake method that is so popular in the keto world, the coffee sponge cake is baked in the microwave in 1 minute. The mascarpone filling takes about 10 minutes. In just 15 minutes you will have an amazing dessert to wow your Valentine.

Tiramisu means pick me up in Italian and originates from Treviso, Italy in the 1960’s. A traditional tiramisu would usually consist of ladyfingers dipped in coffee, layered with a mascarpone filling and dusted in cocoa. As ladyfingers are not keto-friendly, the microwaveable coffee cake is an excellent substitute.

Baking and Dessert Serving Dish tips

  • The mug in which you microwave your cake should be similar to the diameter of the glass you will serve it in. As a result, it will make the assembly of your dessert easier.
  • Using a mug that is smaller at the bottom and wider at the top would create in a cake with an uneven shape. As a result, it wouldn’t make 2 even discs when you cut it in half.
  • When choosing the glass you would like to use to serve your keto tiramisu in, we would recommend a small glass, as this is a rich dessert you won’t need to fill a big glass. We used small drinking glasses we had in the cupboard and they worked perfectly.

Ingredients and substitutions

  • This recipe calls for the use of hazelnut flour/meal. We love hazelnut flavors and they worked well in this keto tiramisu. Should you be unable to find hazelnut flour, you may substitute almond flour and obtain the same result.
  • Get creative with your coffee flavors! We chose a hazelnut flavored instant coffee, but you could use any coffee flavor you prefer.

How to get the best results with your Keto Tiramisu sponge cake.

  • Take into consideration that microwaves vary in power. For this reason, you should check your cake after one minute. If it doesn’t seem cooked, you will need to return it to the microwave for a little longer.
  • Check your cake for doneness by inserting a skewer into the center of the cake. If it comes out clean, it is ready. If there is batter on it, you will need to bake it a little longer.
  • Be sure to grease your baking mug will with coconut oil butter or coconut oil. This will help to remove the cake from the mug.
  • If the cake doesn’t just tip out, run a butter knife around the edge of it to loosen the sides.

Challenges with Keto Baking

This keto tiramisu recipe takes the traditional tiramisu and adapts it to make it keto friendly. One of the biggest difficulties when baking with keto ingredients, is getting a crunch. We knew we were going to struggle to replicate ladyfingers, so we created a coffee flavored sponge cake that we could use instead. Mug cakes are a very popular dessert in the keto world, so we decided to develop a keto coffee mug cake to substitute the ladyfingers with.

One of the best things about keto baking is it’s quite easy to substitute the sugar with sweeteners. We love to use an erythritol and stevia blend. Some of the best options are Swerve and Sukrin.
