Ok, so you’re probably so over mug cakes and you’re probably rolling your eyes at me right now but STOP! I promise you this isn’t like any other mug cake out there. I’ve tried a bunch of mug cakes and I hated them. I thought they were a really neat concept for a quick dessert fix but nothing would ever beat baking an entire cake or cupcake. I hated that all the mug cakes came out SPONGY and they had the grossest texture.

Last week, I was CRAVING chocolate like none other. It was a pretty dire situation. We didn’t have any desserts in the house because I hadn’t been baking and I didn’t want to run out to get anything so I thought I’d give a mug cake a shot. It ended up turning into a recipe development hour because the first batch came out horrible. Like, I threw it in the trash can and it was just one lumpy sponge thing. The second one was slightly better but still really bad. The third, I switched out some ingredients and added a little bit more of some and it came out how I wanted but I knew it could’ve been better so on the fourth try, I finally got it to work and the exact texture I wanted.

You guys, this is the moistest chocolate mug cake I’ve ever tasted before. I’m not joking! You have to try this and see for yourself. It’s a great alternative to baking an entire pan of brownies & it’s a super awesome quick fix for that chocolate craving! Jason loved it and said it tasted like brownies! Yay :)

This best and moistest chocolate mug cake you will ever have. It's not spongey or dry like other mug cakes! You will never use another chocolate mug cake recipe again!

Servings: 1
  • 1/4 cup all-purpose flour
  • 2 tablespoon unsweetened cocoa powder
  • 1/4 teaspoon baking powder
  • 2 tablespoon granulated sugar (you can add 1 tbsp. more if you like it a bit sweeter)
  • 1/8 teaspoon salt
  • 1/4 cup + 1 tbsp. milk
  • 2 tablespoon vegetable oil
  • 1 tablespoon hazelnut chocolate spread
  1. In a medium bowl, whisk together dry ingredients.
  2. Whisk in the milk and vegetable oil until all ingredients are combined and batter has no clumps.
  3. Pour batter into a microwave-safe mug. Mine was a 14-ounce mug. You want enough head space for the cake to rise without pouring over.
  4. Add 1 tbsp. of hazelnut chocolate spread in the middle of the batter. Just drop it in the middle, no need to push it down and sink it in the batter.
  5. Place a paper towel into the microwave and set the mug on top (this is to catch any batter if your mug cake overflows).
  6. Microwave mug cake for 70 seconds on high (PLEASE READ NOTES CAREFULLY BELOW)
  7. Carefully remove from microwave and enjoy!
Recipe Notes

Please note that ALL microwaves are different therefore can yield different results and can overcook this mug cake if you aren't careful. My microwave is 950 watts and I cooked mine on 100% power for 70 seconds. Knowing this information, it may help you better judge how long to cook yours for and at what power.

You can totally omit the tablespoon of chocolate hazelnut spread if you want or use a different spread of your choice (peanut butter, biscoff, etc.). I just thought it made the cake even more moist but the cake itself is moist enough without it!

**This recipe is specifically made for the microwave. I developed it for the microwave. I don't know cook time or temperature for an oven...I'd imagine it'd be a very quick cook time at a low temp., but since I didn't test the recipe for an oven, I cannot give specifics. Sorry!

No eggs? Correct. There are NO EGGS in this recipe. Why? Egg is what makes the mug cake spongy. If you think about it, when you bake a full-sized cake, you typically use 1 or 2 eggs...for a mug cake to use 1 egg is A LOT!

Self-rising flour? I have tested this with self-rising and it does NOT work. At least I felt it didn't work because it was too spongy for me. You are more than welcome to use it, however, please keep in mind that I don't recommend this method.

    I can’t make it work. Tried it twice and the cakes didn’t rise. This never happened to me with any other mug cake recipe, but they all had eggs. The second time I even doubled the baking powder and nothing happened.

      Instead of all purpose flour I use self raising flour and it raises beautifully

      How old is your baking powder? Is it stored airtight? That might be the problem. I just made for the first time and it came out perfect.

    I rarely make comments on recipes I try but felt I had to on this one. I have tried multiple mug cakes all with poor results. But this one was the best. Moist, not dry and with the texture of real cake not rubbery like others. The only change I made was I added just a hint of vanilla. I had to keep an eye on the microwave, mine took just over 75 seconds.

    Perfect! New goto recipe. 60 secs in a 1000w, split into 2 mugs for two small treats. Topped with lemon curd instead of hazelnut spread.

    Made this with gluten free SR flour as it was all I had in the cupboard and this is hands down the best mug cake I’ve ever made! It was tasty and moist and not like an old sponge at all. I added a TBSP of hazelnut butter and a TBSP of dark choc chips as I didn’t have Nutella and it was delicious! Definitely saving for future late night cake cravings xx

    I’ve tried over 50 different mug cake recipes and have never come across one so delicious and moist. Was absolutely brilliant!

    I am sorry to say this is the most disgusting thing I have eaten in at LEAST THREE MONTHS! I had long since given up on mug cakes, and had a sudden chocolate craving, much like the author of this recipe and thus a change of heart. WELL! I regret that. It also took me not 2 minutes, but fifteen times that to make. It had an extremely unpleasant taste and texture, and it did not rise at all.

    This was really yummy and moist. Mine didn’t really rise much as others have said so it was quite dense but still had a nice texture. I actually used milo and 1/2 the sugar instead of coco powder only because I realised after I started that I didn’t have any. Great with a scoop of ice cream on top.

    Tirned out very spingy but somewhat dry and less sweet (could be the sugar) .I will adjust sugar to add sweetness ,but what should i add more make it moist ? Oil /milk or other suggestings ?

      What’s the wattage on your microwave? Maybe cook 15 sec. less and check?

    While this mug cake didn’t not have much flavor, I would say it met my expectations considering it is made with a microwave.

    This is my go to cake when I need a single girl cake hit. Just made it without putting the veg oil in and it still turned out yum! Whoops in a good way.

    Oh wow|! Delicious…I think. Made the mistake of using Hershey’s special dark cocoa and forgot you need more sugar when using. It was a little on the bitter side, but soooo chocolaty. I don’t know where you get those big mugs from…mine are all 8 oz. So I used a small, individual round glass casserole dish. Perfect texture. Will try again…but with more sugar. Oh, by the way…DEFINITELY needs a big scoop of ice cream!

    I tried this and omg – it is quick, easy, and yummy!! My 3 yr old did the mixing, and we split the batter in two cups. Half was enough for her dad and I…she had a couple of bites from mine, but she’s not much of a sweet tooth, thank goodness. Thank you for the recipe!

    This is the only recipe that I’ve come across that actually works. I definitely put more sugar in before I even tried it because I know what I’m about and that’s sweetness. This was awesome, thank you so much.

    Absolutely delicious, great recipe – simple, quick and easy. Used peanut butter in mine, yum! Highly recommend :)

    This was delicious ☺ my first attempt at a mug cake was disgusting and almost put me off trying again, We have a house full of easter eggs but I wanted something more puddingy so after an intense Google session I decided on this recipe and I’m glad I did, I’ll definitely make it again.

    This really was cakey and moist and delicious. I did the annoying thing and changed it slightly after reading comments and did just 1 tbsp of oil. I also did a mix of 1tbsp dark brown and 1tbsp of granulated. I think my microwave is 850 watts so I went straight in with 90 seconds and it was cooked to perfection.

    Oh my! Perfect for a mid night fix. Exchanged vegetable oil for butter because I ran out! It’s amazing. Super moist and chocolate-y! What more do you need?
