Flourless Nutella Mug Cake

I’m really excited to share this recipe with you today. I spent a few hours fiddling in the kitchen to make this dessert for FH, and I’m absolutely thrilled with how it turned out.

A flourless Nutella mug cake. It sounds as good as the name. It’s super easy to put together. Just five ingredients. A little stir. Microwave for less than 2 minutes. And you’re treated to a decadent, moist, flourless Nutella cake.

Because it is flourless, it also pulls away from the cup easily so you can actually transfer this into smaller cups for a prettier presentation. After I finished making the mug cake, I cut it in half and placed each half in one of these heart shaped teacups I bought a while ago on a whim.

I got the idea from No Recipes who created a flourless chocolate cake. It made me realize that if a flourless chocolate cake was possible in the microwave, then so was a flourless Nutella cake. This is my favorite mug cake to date. I’ve already made it three times this week. I hope you love it as much as I do.

Here are the rest of my mug cake creations:

Flourless Nutella Mug Cake

Servings: 1 mug cake
Prep Time: 4 minutes
Cook Time: 1 minute
Total Time: 5 minutes
Course: Dessert
Cuisine: American
All you need is five ingredients and a few minutes to make this decadent flourless Nutella cake.


  • 2 tbsp Nutella
  • 1 tbsp sugar
  • ¼ tsp baking powder
  • 1 tbsp heavy cream
  • 1 large egg


  • Mix all ingredients into a mug. Make sure you thoroughly scrape 2 tbsp of Nutella into your mug. A lot of times, much of it sticks to the measuring spoon and it can throw off the recipe and make it taste too eggy.
  • Stir with a small whisk until all ingredients are thoroughly blended in the batter, especially the Nutella.
  • Microwave for about 1 min 15 seconds. Check on the cake. The top of the cake may look wet and moist but see if the inside section is set and cooked. If it is, you are done. But if you are worried that the wet part might still have raw egg, remove the thin top layer and flip over so that the wet part is sitting inside and no longer facing the top and microwave for about another 20 seconds so that the wet section cooks. Careful not to overcook or else batter gets too dry. Total cook time should be around 1 ½ minutes, and no more than 2.
  • Wait for the batter to cool before eating, about 10-20 minutes. I don’t recommend eating this straight out of the microwave because it sometimes has a little bit of an eggy taste which goes away if you let the cake cool and set.

  1. This recipe looks great! I haven’t tried it yet, but what’s the texture like? Thanks!

  2. Do we have to use baking POWDER? can we use baking SODA??????

  3. This is wonderful! Thank you.

  4. Hi

    Can you use greek yogurt instead in this recipe and how much do you think I should use?


  5. Oh, Yummy-Yum-Yum.. I just dropped a glob of peanut butter right in the center of the nutella batter(do not stir)and it was sooo Yummy!!!! This is my favorite mug cake so far…

  6. OBSESSED!! SOOOOOOOOOO GOOD!! I added a some twists to it though. I combined crushed graham crackers with a bit of butter and made a crust with it. I “baked” the crust in the microwave so it became hard. Then I poured half the batter on it, and put 2 marshmallows, then put the rest of the batter! Nutella s’mores mug cake! 🙂

  7. Read all your posts about mug cakes before I gave into the temptation and made one today. Simply yum! Thanks for all the easy to follow recipes 🙂 love the site

  8. Sounds good thank you! I was actually able to get some milk today so I‘m definitely going to try this out 🙂

  9. Is there anything i can subsitute the heavy cream for? Im a teen that lives alone and dont havs money to go buy any and also just ran out of milk 🙁

    • I’m sorry, I don’t know. I haven’t tried doing a substitution. Also if you don’t have milk either, that makes it even harder. I was thinking maybe milk and butter to sub heavy cream, but I’m not sure how you would do the recipe without milk. I do have a ton of other mug cake recipes, and you might be able to make one with the ingredients you do have.

  10. Is it ok if I use cereal cream? (10%) or will it affect the taste?

    • I’m not sure what cereal cream is, so I don’t know if it will. I say give it a try! It’s only a few ingredients so it’s not like an entire large cake wasted if it doesn’t work out.

  11. I used TruMoo (1%chocolate milk) instead of the heavy cream. Extra chocolatey and turned out great.

  12. I just made this… with 1T coconut milk creamer, because it was what I had. It was delicious…there was one eggy bite towards the buttom, but maybe I should have let it sit a few more minutes. Easy quick moist delicious… and I only got a little nervous to see the batter rise halfway out of the mug in the miss microwave.

  13. To the person who asked about a healthier milk substitute – I used greek yogurt and it turned out fine! I also only used the egg white 🙂

  14. I saw these a while back and will be making them for my husband’s and my birthdays. I recently kicked wheat to the curb, and these are PERFECT!!! Thank you!

  15. Delicious! It was the creamiest cake I’ve tried in my life.

  16. love all your recipes! gotta try this soon 🙂

  17. Love the heart mugs! So cute! Recipes with 5 ingredients or less are right up my alley! I plan to make this cake this weekend…

    Gotta use up my Nutella!

  18. I think I didn’t put enough nutella in it, it still tasted very eggy:(

    • I’m sorry to hear that. I’ve made this a few times now with no problems, but you definitely need to make sure you put a full 2 tbsp of Nutella. And at least 1 tbsp of sugar. And you should wait for it to cool before eating.

  19. would regular milk work so that I could eat this “healthily”? I am also in love with those adorable heart shaped mugs!!

    • In this case I’m not so sure. The heavy cream basically is the fat and oil for this recipe since it doesnt use butter or oil. I’m not sure how it would taste with regular milk. It’s only a tablespoon of cream though! So I think you should be okay. If I experiment with regular milk I’ll let you know.

  20. Looks delicious! And I love the heart-shaped mugs :o)

  21. Wow….so delicious
