3 Ingredient Flourless Nutella Mug Cake

This single serving Nutella mug cake is ridiculously easy to make with just 3 ingredients. It’s rich, dense, chocolatey and everything a flourless cake should be.

You may recall earlier last year I posted my 2 Ingredient Flourless Nutella Mug Cake, a recipe I created for my 5-Minute Mug Cakes* cookbook. It remains one of my favorite recipes to date, but a lot of readers were avoiding it because the recipe requires the cake to rest for several hours (even though it only takes 5 minutes to make).

Well, I listened and set about creating a version that doesn’t need a long wait time. This cake only requires you to wait 15 minutes. You can do that right?

It took quite a few tries and the opening of a new jar of Nutella, but I did it. I confess, I adore opening a new jar of Nutella. Whoever came up with the packaging is genius, using that gold foil seal. Every time I open it, it’s like tearing into a present.

This version is little more chocolate intense and not as Nutella-y as the original 2 ingredient version, but it’s delicious and the trade-off is that you can eat it right away.

The cake is not overly sweet, tasting like melted dark bittersweet chocolate. If you like yours to be more sugary, you can always drizzle some chocolate syrup on top. I topped mine with a simple powdered sugar.

Because this cake is so rich, the portion is small. When the cake cooks, it will rise quite a bit so you’ll need to cook it in an oversized mug. After it’s done cooking, it starts to shrink down and condense. Once you let it settle for a few minutes, you can scoop it out and plate it in smaller mugs or dessert plates. I bought these adorable espresso sized mugs to plate mine in.

  1. Can I add cocoa powder instead of dutch cocoa powder? will it still taste good and be ok

  2. Hi,  I am from Australia. (Western Australia (WA. ). Your recipe looks wonderful.
    Can you please assist?  
    The recipe calls for Dutch processed Cocoa powder.  I have not seen that in WA.  Would normal Cadbury Cocoa powder be ok to use and do you need to adjust the recipe at all?

    Many thanks for your help and hope to hear from you soon so that I can make it.

  3. Delicious and easy! Midnight snack for my daughter and I…honestly one cake is suffice for 2 people to share. Thank you for a simply decadent treat.

  4. Perfect for spend a cold, rainy night in Sydney lockdown! A tremendous recipe that no-one can believe when they see it. Thanks SO much!

  5. Yumm. Enjoyed this new discovery, so easy and taste good. Thank you

  6. So happy I found this quick and delicious recipe! (THANK YOU!) Added an extra 30 seconds in my 700W microwave, and it was perfect. Drizzled with honey for a little added sweetness.

  7. Have tried several mug cakes and this one has the best texture.  Added a dash of cinnamon .   It made such a good dessert.  

  8. Oh my word….this is so addictive, so easy, so quick and so absolutely delicious….love it!!
    Thanks for sharing.

  9. I simply love Nutella and then wham I see this recipe and thought just too good to be true but oh my word now I am addicted….love it. Thank you for sharing.
    PS: Love peanut butter too so have got to try it with some variation ?

  10. Is it supposed to be jelly fudge type

  11. Okay, so I was hungry for a mug cake but was feeling really lazy. I happened to remember saving this to my Pinterest board, and considering how simple this is, my expectations were not that high. I was very pleasantly surprised by how good this is. This’ll probably be my new go-to snack, so thank you.

  12. I absolutely love this recipe. By far the best. I recently started making mug cakes because I have been craving something warm and chocolatey. All of the recipes that I tried came out rubbery. ? However, this one came out perfect! Absolutely perfect! Totally recommend it. I switched up the ingredients a bit… instead of dutch pressed cocoa (I have no clue what that is… lol) I actually used Nestle Quick cocoa powder… it worked fantastic! Thank You soooooo for this recipe! ??????????

  13. All I can say is oh my god! This is like the best cake I have ever tasted. Honestly! I have had a chocolate craving for like a week and decided to make some brownies. I ran out to the store and grabbed some mix. Found this recipe and was like “ AND I DIDNT EVEN NEED THE STINKIN BROWNIE MIX!” 

  14. Just found this site and recipe. Didn’t get much rise from the cake, probably due to using a soup mug. Could of gotten better results if I’d tripled or quadrupled recipe or used smaller mug. Otherwise the cake is good for a chocoholic fix.

  15. Hi! Can we use coffee powder as a substitute for cocoa powder ? I know it will taste a bit different but will the results be same ?

  16. You had me up until the “wait 15 minutes” part… ????

  17. Thank you so much for the AMAZING recipe! this is by far the best mug cake recipe I’ve tried! I didn’t have dutch processed cocoa powder, so I just used natural cocoa powder, and it still tasted great! Thanks again.

  18. Just made this again tonight! Lovely! I added 1/2 teaspoon vanilla, and whipped the egg before adding other ingredients. Texture is amazing. I had to cook mine a bit longer, it still came out fantastic.

  19. used a bit of hot cocoa powder, made 2 for myself at work =X THANK YOU!

  20. Hii! I’ve recently started experimenting with baking / microwave mug cake recipes…this is THE ONLY recipe so far that has gone into my personal reference cookbook 🙂 thank you so much for sharing…amazingly simple to make! And it’s just too delicious for words! I topped it with some condensed milk (ouch my diet!)…to heaven and back! Yum!????

  21. Thank you for posting this! It was surprisingly good!

  22. this is delicious thank you for this flourless recipe 

  23. I love how it’s so easy but mine didn’t rise. It raised in the microwave but went back down. Is there a way I can make it better?

    • Hi, you can try to cook it a little longer. Yours might have needed some more time in the microwave. However, keep in mind this cake is supposed to rise and then condense back down. Much like other flourless cakes, it should be more dense than fluffy. I describe the size more in detail in my post. After I cooked it, I then put them into espresso mugs for plating because they do shrink quite a bit. You can see the photo of it on the plate to get an idea of how tall it was once it was done shrinking.

  24. this was sooo good… I always go to your blog if i want to make a mug cake and I’ve never been disappointed : D

  25. Don’t you need to grease the sides of the mug?
    What setting on the microwave, i.e., HIGH?

    • you don’t need to grease it. the cake will pull away from the edges of the mug on its own. Also, not sure where you are writing from, but I just used the full regular power on my microwave, no need to adjust setting.

  26. Kudos for posting this amazingly easy and delicious recipe. The hardest part is to let the mug cake rest for 15 minutes ???? delish!

  27. Didn’t have enough nutella for a cake, substituted peanut butter instead and drizzled nutella on top. Delicious! 🙂

  28. I live in a dorm and I have carnation instant breakfast chocolate powder. How much of a bad idea would it be to use that instead of buying cocoa powder? (college kid budget)

  29. I tried this recipe, but the batter never grew as a cake, but just got spilled in the mug, very strange. Is there any trick?

    • make sure you thoroughly mix the batter with a whisk. The egg has to be completely mixed in. You should spoon up the batter a few times and make sure there are no unmixed egg streaks. Also, you are cooking this in the microwave right? because it won’t work the same in an oven.

  30. Just made this and it was nice. Is it meant to be a fudgy texture?

  31. This looks soooo good and sounds so easy too, which is always a plus. Can I use natural cocoa powder instead of the dutched one?

  32. This looks super yummy, and so fast for a quick treat!  Unfortunately, I’ve just sold my ancient microwave and still haven’t bought a new one yet….is it possible to cook this in the oven?

  33. This is a great recipie! Made them and gluten free too, loved them! 🙂

  34. I have tried many chocolate mug cakes and this tastes just as good as the rest of them. I was a bit sceptical of a gluten free cake but the flavour and texture is all there. And its so much easier with only 3 ingredients 

  35. Mmm that sounds amazing! So rich and chocolaty. Love how easy it is, too 🙂
