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 :)

Ingredients

  • 1/4 cup all-purpose flour
  • 2 tbsp. unsweetened cocoa powder
  • 1/4 tsp. baking powder
  • 2 tbsp. granulated sugar (you can add 1 tbsp. more if you like it a bit sweeter)
  • 1/8 tsp. salt
  • 1/4 cup + 1 tbsp. milk
  • 2 tbsp. vegetable oil
  • 1 tbsp. hazelnut chocolate spread

Instructions

  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 Type: Dessert

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 was able to make this Gluten-free by subbing Bob’s Red Mill GF Baking Flour and increasing the Baking Powder to 3/8 tsp. I also added a 1/2 tsp of Vanilla just out of preference.

    Definitely the best GF chocolate mug cake I’ve had!

    Would it be okay to substitute normal milk for almond milk?

      Yes, absolutely

      08/20/2016 at 9:16 pm

      Yes, I did that because I couldn’t find the regular milk.

    Very good and easy and turned out perfect! Baked for 70 seconds although I don’t know what my microwave wattage is, and had no Nutella. After baking, I topped with chocolate ganache and whipped cream leftover from another dessert. Excellent and perfect for two. Thanks for this delightful recipe and well written instructions.

    I don’t usually comment but I just had to comment in case anyone had any doubts about this recipe. I made this a while ago and it was amazing! Exactly like the picture, so moist and chocolatey. My microwave is 1100 watts so I adjusted it accordingly and reduced the power to 90%, put it in for 70 secs exactly and it came out perfect! Tastes even better than a lot of similar larger chocolate baked goods that I’ve tasted!

    I made this just a few minutes ago and it turned out perfect! I only had SR flour, but the texture was VERY good anyway. :D This will be my “go-to” recipe when I have a craving for chocolate cake. Thanks for sharing .

    Tried making this but its really floury tasting and pretty much inedible. Went in the bin. I think egg might have saved it.

    Do u need the hazelnut chocolate spread? Or can u switch it to something else like peanut butter?

    • Julie
      07/30/2016 at 8:55 am

      No, you don’t *need* it; many others have used PB, almond butter, chocolate chips…anything, really.

    Thanks – This worked perfectly!! I used Biscoff spread in place of hazelnut spread – recommended!

    Im kinda disappointed in this. I may be the only one to say this, but i followed the recipe perfectly and my cake just wouldn’t cook! it spent a total of what i would estimate to be 10 minutes in the microwave before i smelled burning. when i put a fork in the mug all the way to the bottom, the bottom inch or so had hardened and burned, and the top of the cake was still completely raw! I don’t know what happened but it definitely not a good experience :(

    • Julie
      07/31/2016 at 8:51 pm

      Sorry it didn’t work out for you but….10 minutes in the microwave?? I’m not quite sure what to say about that because anything that goes 10 minutes in the microwave would definitely cook, hence why your cake burned at the bottom. The top of the cake should’ve cooked first.

    • Anomynous
      08/10/2016 at 8:42 am

      Maybe it had something to do with the mug you used? You should try it with a better quality mug and see how it goes.

    it was lovely! will make again! :) I’d like it to be maybe more light so I think I will experiment with the amount of baking powder :)
    But the overall it was best I had :) nice and moist!

    This cake came out perfectly light, fluffy and moist and the Nutella was a great add!!!! I added 1/2 tsp vanilla extract, evaporated milk w/ a bit of water (a Bahamian thing lol….no milk on hand) and sprayed my mug with a bit of cooking spray and had no issues whatsoever. I added a dollop of whip cream on top (next time will try with cookies and cream ice-cream). Thanks so much for sharing!!!!

  22. Mac
    08/03/2016 at 8:45 pm

    I followed all steps, the texture is perfect, and I topped with chocolate chips instead of nutella. The only problem, was that I should’ve done the extra tbsp of sugar, not sweet enough for me. So I added more chocolate chips :)

    Hi, your mug cake seems really good, but if my microwave has a max power of 700W what can i do?

    • Julie
      08/05/2016 at 7:09 am

      You can just cook it longer than the time in the recipe.

      • Marco
        08/05/2016 at 7:31 am

        How much time would you suggest?

      • Julie
        08/05/2016 at 7:41 am

        My microwave, as indicated in the recipe, is 950 watts. I cooked it for 70 seconds. If yours is 700 watts, then I suggest maybe 90 seconds or 100 seconds? I would just give it a try and keep going at 10 second intervals if it’s not cooked enough for you.

    Just made this and loved it!!
    I made a few modifications:
    Added 1/4 tsp vanilla, about 1 1/2 TBS of shredded coconut, and one marshmallow in the center. So yummy!! (I didn’t have any Nutella….)

    70 seconds is perfect!

  25. Patty
    08/06/2016 at 6:37 pm

    Yum! I used coconut oil instead of veggie and caramel sauce in the center. So good!

    Made this earlier this evening. It was absolutely delicious! Had to make more for my two brothers cause they were craving it too. Our microwave is only 650 watts, so I baked them for 2 mins. Will definitely be trying it with peanutbutter sometime soon.
    All in all two thumbs up!

    You stated that you had tried this recipe with self raising flour and it didn’t work, but did you know that by mixing all purpose flour and baking powder you are making self raising flour. So you actually did use self raising flour. Looking forward to making this.

    I’m new to mug cakes (I am a traditional amateur using butter/ eggs and oven to cook my cakes. Very often this method takes much time n effort. I was greatly surprised when I followed yr recipe (I was not convinced at all at first especially about the 70secs microwave time) but then SURPRISE!! I was overjoyed!! Your recipe just changed my life!! Thanks so much!!!

    I just tried this and it was great! I doubled the recipe and used evaporated milk (no milk on hand) and one extra tbsp of sugar between the two mugs. It was perfect. My microwave is 1100 so I only did a minute. I would definitely make this again with some chocolate chips or hazelnut cream.

    After trawling the internet for a chocolate mug cake recipe to make for dessert tonight,I ended up making this one. SooooOoOOOooo damn good!! I had a spare couple of squares of dark chocolate in the cupboard and pushed that slightly into the mixture. Also used cocao instead of cocoa and coconut sugar.

    This is the best chocolate mug cake i have ever had! I have made this twice and both times it was excellent. I slightly reduced the cocoa powder at the second time because the cake turned a bit bitter.
    Thanks a lot!

    I never really post but this cake definitely deserves a post! Was absolutely delicious! Only had self raising flour and still turned out amazing! Ended up eating my husband’s half as well!! Definitely give it a try!

    I doubled the recipe and split it into 3 portions in regular sized mugs and microwaved it for 55 seconds and it came out perfect! Me, my husband, and my daughter LOVED it! My daughter was amazed that you can cook a cake in the microwave. We put a few chocolate chips on top and it just completed it. Thank you for sharing this recipe!

    I LOVE this mug cake so much! I first found this recipe a while ago when I was searching for mug cake recipes after the first few I found turned out to be a bust. But this recipe is absolutely amazing! Since I found it, I keep going back to this! This is my “treat yourself” dessert for whenever I’m craving something sweet even if we do have cake in the fridge I will always go back to this recipe. I’ve tried this recipe by stuffing half a twix bar in it, a chocolate bar, peanut butter and Nutella – as per your recipe, and just tonight when I found my pantry lacking some cocoa powder and a huge craving for Oreos I used this recipe for an Oreo mug cake w/o the cocoa and it worked perfectly fine. This recipe is just perfect and absolutely divine! It’s moist and sweet and is just amazing!

    Why is my cake not as pretty as yours? And also, the mug I used is only 12oz mug but it did not occupy the whole mug just like yours because you used 14oz mug. I was expecting it to overflow because I used a smaller mug. I wonder what’s wrong but I sure did follow your instructions religiously.

    08/20/2016 at 6:03 pm

    This is the best mug recipe ever. It pleased a house hold of chocolate cake lovers and the best thing is that I made a gluten free one for my mom just had to add a bit more baking powder. And instead of hazelnut spread for
    My dad is used a piece of Cadbury chocolate bar and he was amazed. Thanks for an amazing recipe.

    I made this recipe in a ceramic pan instead of a mug because I was feeding 2 people.It wasn’t very much. How can I fill the whole pan?

    • Julie
      08/20/2016 at 9:29 pm

      What size was the ceramic pan? This is a mug cake made for 1 and if you were feeding for two using a large ceramic pan, it won’t work. You may need to double or triple the recipe, depending on how big your pan is, but even then, I still feel like this would turn out better if it were in a mug since this is a mug cake recipe.

    this was awesome!i just googled a quick mug cake for my 5 year old who is in bed with pneumonia. i didn’t realize i didn’t have cocoa until it was too late so i made it without and it still came out delicious. i threw in some chocolate chips instead of nutella because he doesn’t like it. he LOVED it. of course i then had to make myself one- with the nutella. excellent! for anyone who didn’t get the right consistency, it has to be your microwave or the cup you used!
