This quick keto tiramisu delivers an easy dessert using a low carb mug cake, soaked in coffee and rum in between layers of a creamy mascarpone cheese mixture. The sponge is made with coconut flour making it gluten free too.

If you need a creamy dessert in a hurry, this easy 10-minute tiramisu can be in your dessert bowl with minimum effort. Bake the coconut flour sponge cake in 2 minutes, as it cools, whip up the creamy filling, assemble and voila! Tiramisu dessert ready to go!

I prefer coconut flour for my sweet mug cakes simply for my personal preference, but you could use almond flour too. Add another tablespoon of almond flour and reduce the coconut milk, or even replace it with almond milk and you have a quick and easy cake.

The cake mixture is split into two ramekins to ensure an even sponge to be sliced and assembled for a tiramisu. I had tried cooking it in one ramekin dish, but it rose unevenly and I was not happy with it. Especially when it came to slicing the mug cake as I wanted even layers, as you would expect in tiramisu. It tasted good but did not look appetizing.

I love Tiramisu as a dessert and have also enjoyed it in cupcake and cheesecake form. There must be more I can do with it! However, the Chief Taster tries to rain on my parade with “it’s just cake and cream”. What’s not to love about that!? It has rum and coffee too. Almost a Caribbean delight! Mind you, he prefers a plain sponge cake which I look at with disgust. Takes a merging of opposites to make a good marriage!

Try to use ramekins the same size as the serving glass or dish you will be using for ease of assembly. I used a glass tumbler which was great for photos but ended up being a large dessert a bit too much for one. That’s why I have this listed as 2 servings. If you use a large tumbler, it’s a romantic dish to share!

You could cut the mug cake sponge up into fingers, just as you would use in a traditional tiramisu and that might fit another serving dish better.

For the coffee, you want a strong one such as expresso, but you may want to add low carb sweetener to it to relieve some of the bitterness. I have used an instant coffee without sweetening and won’t do that again! Or I should have added more rum for a balance.

Although I have recommended you chill the recipe for at least 30 minutes, it can be enjoyed as soon as you assemble it.  As we both can testify as part of research purposes!  I couldn’t wait once it was assembled so had to dig in with a spoon!

I use a couple of tablespoons of rum, but you can add more or omit it depending upon your personal taste.  As I live on an island with great rum, it would be rude for me not to use it!
