An Italian classic turned into an easy microwave low carb keto dessert recipe

The best thing about this keto tiramisu is how easy it is to make. The cake is baked in a mug in the microwave and is ready in just 1 minute. The mascarpone filling takes about 10 minutes. In just 15 minutes you will have an amazing dessert to wow your loved one.

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 coffee cake made in the microwave is an excellent substitute.

Baking and serving tips

  • Cook the cake in a mug that is similar in diameter to the glass it will be served it in. This will make the assembly of your dessert easier.
  • Use a mug that is straight and consistent in size. A mug that is narrower on the bottom than it is on the top will result in an uneven cake layer
  • Use dessert shooter glasses or short drinking glasses to assemble the keto tiramisu. This is a rich dessert and you won’t need to fill a big glass.

Make this tiramisu your way

  • Substitute almond flour for hazelnut flour and obtain the same result.
  • Get creative with the coffee flavors! You could use any coffee flavor you prefer. Some ideas would be Mocha, French Vanilla, or Caramel.
  • If you don’t have mascarpone cheese, full-fat cream cheese can be used.
  • Use this homemade coffee liquor (keto-friendly) to replace the brandy.
  • Sprinkle the top of the keto tiramisu with sugar-free chocolate chips.

Tips to get the best results with this keto dessert for two

  • 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.

Keto baking challenges

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.

Lady fingers are the cookie/cake part of a normal tiramisu. They are a firm and crisp cookie that is not keto-friendly. They are normally soaked in a coffee and brandy mixture, softening the lady finger while infusing flavor.

The coffee flavor was infused into this cake by baking the coffee into the mug cake. Since the mug cake is moist to start, the only liquid to soak into the cake is the brandy.

Keto tiramisu is an excellent dessert to serve your special Valentine, or even just as a date night dinner. The silky smooth mascarpone filling paired with the soft and moist coffee cake is the perfect end to your special evening.
