Why You’ll Love This Recipe

I love a good tiramisu, but it’s one of those dishes that I don’t go through the hassle of making unless I’m having company. Sometimes, though, I want to have the ability to enjoy it just for myself, with all that extra work.

Enter the tiramisu mug cake, which is the perfect single serving portion (or make two mugs for date night, it’s that easy)! The cake replaces traditional lady fingers in this recipe, and then it’s loaded with sweet mascarpone and coffee flavors for the ultimate bite!

Best of all, it “bakes” in the microwave in just about a minute, for a dessert that’s stress free.

Ingredients List

ingredients to make tiramisu mug cake
  • ¼ cup all purpose flour

  • ½ tsp baking powder
  • ½ tsp espresso powder (or instant coffee)
  • ⅛ tsp salt
  • ½ tsp vanilla extract
  • 1 tbsp butter, melted
  • 3 Tbsp milk (I use 2%)

Coffee Mixture:

Topping:

  • ¼ cup mascarpone cheese (softened)
  • 1 Tbsp powdered confectioner’s sugar

Ingredient Tips and Substitutions

  • Either espresso powder or instant coffee works (I just prefer espresso for the flavor here)
  • You can use whipped cream instead of mascarpone for the topping if you want (it’s just not as traditional)

Recipe FAQs

What Ingredients Are Typically Used in a Tiramisu Mug Cake?

The ingredients often include flour, sugar, cocoa powder, baking powder, milk, oil or butter, vanilla extract, and coffee or espresso for the classic tiramisu flavor.

Some recipes incorporate mascarpone cheese and liquor for a more authentic style.

Can I Make a Tiramisu Mug Cake Without Coffee?

Yes, you can substitute cocoa powder for instant coffee, or use hot water or milk in place of liquid coffee or espresso.

However, keep in mind that the coffee flavor contributes significantly to the authentic taste of tiramisu.

How Long Does It Take to Cook a Tiramisu Mug Cake in a Microwave?

Typically, it takes about 1-2 minutes, depending on your microwave’s wattage. Start with 1 minute and then continue in 30 second intervals until the cake is fully cooked.

Overcooking may result in a dry texture.

Can I Use Gluten-Free Flour in a Tiramisu Mug Cake?

Yes, you can replace regular flour with gluten-free flour such as almond or oat flour. Ensure it’s a measure-for-measure substitute to maintain the cake’s consistency.

Note that the texture does tend to change slightly with gluten free flour, but it will still be delicious.

Can I Prepare Tiramisu Mug Cake in Advance?

Mug cakes are best enjoyed fresh and warm right after preparation. However, you can prepare the mugs of cake in advance and store them in the refrigerator for up to 48 hours.

Add the mascarpone topping and dust with cocoa powder just before serving.

What Toppings or Garnishes Complement a Tiramisu Mug Cake?

Popular toppings include a dusting of cocoa powder, a dollop of whipped cream or mascarpone cheese, chocolate shavings, or even a drizzle of coffee-flavored syrup for an added touch of tiramisu flavor.

Make sure to serve with a spoon!

Recipe Pro Tips

  • To make multiple mugs for entertaining, cook the cakes (one at a time is best) and add the amaretto soak, then store them in the fridge for up to 48 hours. Top with mascarpone and cocoa powder just before serving!
  • Do not microwave your mascarpone to soften it! This will make it separate and turn into soup. Just let it soften at room temperature for a few minutes and you’ll be good to go!
  • My mugs are 6 ounces in size. I wouldn’t go smaller, but larger is totally fine (just expect to have extra space at the top)
  • I have a 1000W microwave and my cake was perfect after 1 minute. However, your times may vary based on microwave wattage, and mug size and type. If you overcook it slightly, don’t panic – the liquid you pour over after will help in this recipe

Final Thoughts

This tiramisu mug cake is the perfect single serving microwave dessert, though you can always make multiple mugs or share if you’re feeling generous! A 1-minute cake replaces the soaked ladyfingers of the traditional Italian dessert for a super easy alternative option.

Flavors of coffee, creamy sweet mascarpone, cocoa powder, and a spongy cake make for the perfect treat. This mug cake is perfect for the holidays, New Year’s, Valentine’s Day, or any night you’d like to enjoy a special treat.

Since tiramisu is normally labor-intensive and makes a giant pan, this is a great alternative if you’re only cooking for yourself or a small group. Is it authentic? Well, no. But, it only takes a few minutes to prepare and is delicious, so I think it’s a perfect compromise.
