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
Ingredients
  • 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
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 Notes

Video for the recipe can be seen by clicking here!

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.

    Is there a reason you used oil instead of butter?

    • Julie

      I wanted a cleaner taste.

    Hey! This recipe is fabulous I used caramel instead of a hazelnut spread and I’m hooked it is the best chocolate mug cake recipe EVER!

    I just made this for my whole family for dessert. At first they were very skeptical but it camwas out great! Best mug cake recipe I’ve found. Not rubbery or too thick or spongey like the others. Thank you!

    can someone help me out please. whenever i try to make a mug cake (this included) it always comes out tasting really bad, like a really dodgey raw flour taste, i know im deffo not undercooking it, what am i doing wrong?

    • Erin
      01/13/2017 at 11:39 pm

      Did you try sifting the flour? Helps to reduce clumps and when it’s mixed into the mug it is evenly distributed :)

      01/14/2017 at 1:16 am

      i just wanted to say WOW!!!! I have tried putting together countless chocolate mug cakes and this is the ONLY one I have found to be delicious and moist and perfect!! Thank you so much for your post .. will be saving this article and using it again…and again and again… :)

      This happened with me as well, I would make sure you’re adding the nutella. If that doesn’t work out, I added more sugar and it was great. Side note, adding chocolate chips was great too!

    Is there any way to make it without milk?

    • Kara
      01/14/2017 at 2:52 pm

      actually I tried it and if you add 4 and a half tablespoons of water instead of milk if tastes basically the same!

    Oh my God. Thank you. And I hate you. This is hands down the best mug cake ever. Was in the same predicament, craving chocolate and had to improvise. Then i stmubled across this magical recipe. Can see this becoming a regular late night treat. Superb!

    I was just wondering if anyone used cold milk, or you warmed it up?
    I put cold milk, and almost doubled the time in the microwave. It is 1000W and after 70 s, it only rose didn’t cook much.
    Even after adding some time inside, and checking it still didn’t look like yours. Left in the microwave hoping that the heat would let it cook. But, then I put it on the cake mode for 2 minutes and it’s very gooey and completely uncooked.
    Does adding slightly extra milk do this to it?

    • Julie
      01/22/2017 at 8:39 am

      I used cold milk, and yes, if you add more liquid to it, you should cook it longer.

      • Aishwarya G
        01/22/2017 at 9:01 am

        But even after cooking for a long time, it was very gooey and was very viscous. If you put a spoon in, it was very thick.
        I made a different mug cake with correct amounts this time and it was better than the first try. But it was still slightly wet / slimy around the sides although I added about 20 seconds to the cook time. Even the centre was a bit sticky

    Best mug cake ever! If anyone interested I used zylatol instead of sugar, skim milk and coconut oil instead of vegetable oil – absolutely superb, thank you.

    01/24/2017 at 5:39 am

    I must have made this recipe 50 times! The absolute best tasting cake. I only cook mine for 45 seconds- after tasting the batter there’s only half a batch to cook! (And that’s the best part about an egg free cake!)

    Found this cool conversion site for microwaves and it seems to be pretty accurate. I did have to add 15 seconds to my converted time. Hope the link works! http://www.erikoest.dk/microw.htm

    I love to add mashed bananas on top as a frosting, it’s delicious!!
    Thanks for the recipe! 😘

    I made this and it turned out great. Very quick and simple. You do need a lot of spread on the top, for it to taste nice and feel moist. With out spread it is bland and a bit dry. Thanks for the recipe.

  25. Hanna
    01/28/2017 at 5:04 pm

    Best mug cake I’ve ever laid my hands on!
    On second go I added a small handful of mini marshmallows and a few chocolate chips to the batter.
    It tasted AMAZING!
    On my next go at this recipe I’ll try adding some homemade strawberry jam.
    Will let you know how it goes!
    Thanks, Hanna

    Thank you for the recipe. I was just craving cake and found your recipe. I 💗💗 it! I also traded out the hazelnut spread for peanut butter. Delish!

    So good. I had all the ingredients but not quite enough of some but still worked fine. But next time I will add more suger.

    Honestly this was amazing. I’ve made this two times now. And was not disappointed. You can also mix around the hazelnut spread. That’s what I did and it’s so good! Thank you for sharing this recipe!!

    I just made this with Nesquik since I was out of cocoa powder. 3 Tablespoons of Nesquik and 1 tablespoon of sugar instead of 2 tablespoons of cocoa powder and 2 tablespoons of sugar.

    This is sooooooo good! I added an extra tablespoon of cocoa powder!

    Since others liked it so much, I’m guessing I did something wrong because mine did not turn out well. I didn’t put anything in the middle so maybe that was my problem.

    02/02/2017 at 9:45 pm

    Just created this using 2 tablespoons milk and two tablespoons pomegranate juice. Wonderful!

    Also, because I’ve had to do it before, subbing a packet of hot cocoa mix for the cocoa and sugar works just fine :) #collegecooking

    R u able to use plain flour instead of all purpose flour or are they all the same thing

      Yes, plain flour is all-purpose. Same thing

    Just made this for my Mom for her birthday. It was really great. This is the first time I have made one of these mug cupcakes from scratch. It is so much better than using a mix. What a great recipe, Mom was impressed. Also we don’t have a whole bunch of cake leftover we have to eat. Yea. That little bit on chocolate hazelnut spread took it over the top. Thanks for your impressive recipe!!!

    Turned out SO well. I did 70 seconds and when I opened it I thought to myself “looks like it needs more time” but I stuck my spoon in it and it felt done so I went for it. It was so yummy and not too sweet. (I did 2 tablespoons sugar)
