    The BEST Chocolate Mug Cake recipe out there!

    Seriously though, 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.

    What is a mug cake?

    I still seem to get this question a lot and a mug cake is literally as it sounds. A cake that is made in a mug!

    It’s great because you don’t need to whip out a bunch of tools to make this simple mug cake.

    This chocolate mug cake is made without eggs. Why?

    Okay, I get asked this a lot too and the reason why this mug cake is made without any eggs is because that is what makes it have a spongey texture!

    If you think about it, it makes sense. Why would you put an entire egg into a mug cake when a regular full-sized cake often asks for one or two eggs?

    This isn’t a full-sized cake. And of course I’m not going to ask you to divide an egg in half.

    Just omit it! Best texture, ever!

    Can I make this with self-raising flour?

    You can, but I tested it with self-raising flour and it just came out spongey and not the texture I wanted.

    I like my cakes light, fluffy, and moist and with the self-raising flour, it just didn’t yield the results I wanted.

    There have been many people who have used self-raising flour in this recipe and didn’t notice a difference so if you’re up for the challenge, I say go for it.

    Can this mug cake be made in the oven?

    No, this was solely developed for the microwave. I have had readers who have baked this but I honestly recall how it turned out and/or what temperature or time.

    5 Hassle-Free Ways to Simplify MealtimeSign up here for all the secrets!


    • 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 or mini chocolate chips


    • In a medium bowl, whisk together dry ingredients.
    • Whisk in the milk and vegetable oil until all ingredients are combined and batter has no clumps.
    • 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.
    • Add hazelnut chocolate spread in the middle of the batter or mini chocolate chips. Just drop it in the middle, no need to push it down and sink it in the batter. It does that on its own when it cooks! :)
    • Place a paper towel into the microwave and set the mug on top (this is to catch any batter if your mug cake overflows).
    • Microwave mug cake for 70 seconds on high (PLEASE READ NOTES CAREFULLY BELOW)
    • Carefully remove from microwave and enjoy!



    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.
    *When this recipe was developed, we were in another house. That microwave in that house took 70 seconds for me to cook the mug cake. When the video was filmed, we were in a new home. In our current microwave, it takes 90 seconds...which is why there are two different times. The fact still remains: all microwaves are different and can yield different cook times, which proves to be true with my two different microwaves in two different homes.
    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.) or even chocolate chips like I used in the video. 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.

  • Morgan says:

    Really good recipe, i would say to get it perfect, remove the salt, at least 1 min 30 and a sweet additive like honey or chocolate spread is needed.

  • Patty says:

    I’m sorry for the people complaining about this deliciousness! I can only think they did not follow the instructions or made some mistakes. I too was craving something very chocolatey but didn’t want a huge cake laying around. Alas, I had no milk but I did have Dark Chocolate Royale Atkins Shakes. Not only did it added a little extra sweetness and chocolate, it was thicker than regular milk. I just added a little vanilla and a tiny bit less shake. I will try this recipe again as written- I’m sure it will be fantastic too but what I’m saying is this recipe is so forgiving….so adjustable. If you like it sweeter- adjust, different kind of oil….or milk….adjust. I used a small bowl as I doubted the size of my mugs and I nuked it for 1 minute 30 even though I have an 1100 watt microwave. I’m excited to try the other varieties. Thanks for the recipe. It’s a keeper for sure. My only complaint it that due to the ease of making this, I will have to restrain myself or I’ll be making it daily!

  • Niamh says:

    I added a few bits to this recipe (it’s past midnight and I’ve got a chocolate craving) . I used butter instead of oil, used a tad more sugar, a drop of orange extract and a tablespoon of chocolate truffle (from m&s in the uk, soo good). So rich and super tasty! Especially with a dollop of clotted cream !

    • Pearl De Vera says:

      OMG! What a great recipe! Tried it to the T, it’s just remarkable! I also also tried it with melted butter, the one with oil is better for me. I do wish I added a tad more sugar… but love the chocolatey goodness of it as is.

  • Seema Chaturvedi says:

    This is amazing!! I tried it yesterday and it turned out to be super delicious!
    Can you please suggest some ways to present it beautifully?

  • Sandra says:

    This recipe was absolutely amazing, I usually crave sweet treats yet I never have any or I can’t find any good ones with my egg allergy. This recipe was great because many other mug cakes that don’t use eggs turn out to be chalky or the ingredients are so bizarre. The mug cake turned absolutely amazing and I already wish to make more after finishing this cup.

  • Carolyn says:

    So delicious! Cooked perfectly at 70 seconds. Topped with whipped cream!

  • K says:

    Traded out the milk for half & half, traded the flour for 1:1 Red Mill gluten free flour, left out the chocolate spread, and I’ve died and gone to heaven! Rich, chocolatey, this mug cake is totally as good or better than any cake I’ve ever made in my life. It did take a little longer to microwave, I added 10 seconds as it was a little underdone by toothpick test. Bravo!

  • Emily says:

    OH MY YUM!!!!!
    This was soooo yummy and hit the spot!!
    Wow! 👏

  • Zoe says:

    I decided to make this recipe but instead I used matcha powder (1 tbsp) and it turned out great!!

  • Alexander says:

    Wooow, it’s amazing! The fluffiest migcake I have ever tasted!
    I cooked many recypes of mugcakes; with eggs and without it.
    But I never cooked some like yours. Delicious, it looked like a cloud!!

    Thank you so much ^u^

  • Aneen says:

    Made it according to the recipe without the chocolate spread. 70 seconds was perfect and it was delicious!

  • Taz says:

    During this hibernation period your website is invaluable. You’ve posted the best mug cakes on the internet, yep the entire world wide web.

  • Lizzy says:

    This was so good! Some modifications I made were to sub out the + 1 tbsp of milk with 1 tbsp of this morning’s coffee. My microwave was 1000 W so 60 seconds was perfect. I am going to try it next with 1/2 tbsp Nutella and 1/2 tbsp crunchy peanut butter next.

    • Lizzy says:

      I forgot to mention that I had dark chocolate cocoa powder.

  • Nina says:

    Yum. Yum
    I didn’t have baking powder so subbed with vinegar and baking soda. Topped with vanilla icecream😋 definitely hit the spot and easy cleanup!
    Thank. YOU

  • Theresa says:

    Was recently craving this mug cake and I remembered I’ve always made this specific recipe in the past because it’s just that good!! Looked at so many different recipe sites before I found this gem again! Highly highly recommend

  • Sancia says:

    I made a few changes by using half the recipe, and using water instead of milk, and added a little coffee powder, it tasted delicious. Also mine got done in 30 seconds and got a slightly gooey center which tasted very appetising and chocolate-y.

  • Tanya Jerry says:

    This is my first time doing this. I hope it goes well. Never made any baked goods in the microwave before.

  • Maria says:

    I love this recipe, it’s my go to recipe when I want something sweet and fast.

  • Parul verma says:

    It’s so easy and ingredients are readily available at home

  • Yas says:

    Perfect! Thank you! Just as you said!

  • Bonnie B says:

    Shelter in place during the Coronavirus crisis. Nothing sweet to eat in the cupboard. Made this chocolate mug cake and it filled the bill ~ loved it! Thanks, it’s a lifesaver!

  • Kristen says:

    This is my go to mug cake receipe! It is amazing – makes gooey lava cake if you don’t microwave it for too long! Love this with 1Tb oil – 1 Tb melted butter mmmm

  • Melissa Gonzalez says:

    I have been trying out a ton of different mug cake recipes and they always come out too rubbery and stiff but this recipe was perfect!! My cake was perfectly moist and tasted like a real cake out of the oven! This is definitely my new favorite!

  • Erin Bush says:

    Amazing!! I struggle with a lot of mug cake recipes being a bit dry and unpleasant, but I loved this!! I would recommend adding slightly more sugar if you’re looking for a sweeter taste, but the consistency was lovely!

  • Koe says:

    You didn’t lie! Finally the good recipe!!!! 5 min ago I was eager to believe that mug cakes are an urban legend.

  • Sonali Deoraj says:

    I veganized it with some plant based milk as well as dark chocolate lindt balls popped in before nuking it, and it’s incredible 😍. Going to have to restrain myself from making it every few hours!

  • Mrin says:

    Hey there! Can I make this recipe using granulated stevia instead of real sugar?

    • Julie Wampler says:


  • Kate says:

    Coming back to make this for the 3rd time 🙂 It’s a brilliant recipe

  • E says:

    Thank you for this lovely mug cake! It works well during this quarantine period when one is running out of ingredients. Substituted the milk with hot water and used generic instant chocolate drink powder, had to tweak out the sugar amount and cook time (must be my microwave put 2 mins in a half) but still turned out beautifully.

  • Amanda says:

    I rarely leave a review for anything, but this was a great recipe. My family of four just shared one of these chocolate mug cakes with a spoon of ice-cream on the side and it was perfect! So quick and easy. I substituted melted butter for the oil as I only had a strong tasting olive oil in the house, otherwise I followed the recipe exactly!

  • Kim says:

    Super delicious. Love the combination with chocolate spread

  • Soumya Mukherjee says:

    Followed this recipe with zero expectations and some skepticism. But this turned out very soft, perfectly sweet, and utterly delicious. Thanks for sharing such a gem of a recipe. My 5 yo loved it and begged for more. Will make again.

  • Emily says:

    Have never made a mug cake before this…. This was amazing!!! So delicious. Split the recipe into 2 mugs and found that 50 seconds was about perfect. Thank you!

  • Laura says:

    Thank you!! The recipe worked perfectly and is the first actually good mug cake I’ve ever had.
    In these times when I can’t just nip to a shop for a chocolate fix it’s a fricking lifesaver.

    …on the down side, they may have to roll me out the house in 4 weeks time.
