    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.

  • Bjrooks says:

    Best mug cake recipe I have tried! Only had 1/4 cup of milk, so added a tablespoon of strong coffee, since my fav chocolate cake recipe has coffee. DELICIOUS! Thanks for sharing!

  • Barbara says:

    Just made this. My favorite dessert is brownies and these were SO good, they reminded me of a nice fudgey brownie (I probably undercooked it a bit). I will definitely make this again!

  • Laura says:

    this is the best mug cake recipe i’ve ever tried!! the texture is beautiful and it’s perfectly sweet and chocolatey! i replaced the oil with melted butter because i read that it was better for mug cakes. other than that small change, this recipe is perfect and i would definitely make it again!

  • Jess says:

    If you want these from the oven and not the microwave, 180 degrees Celsius until the top cracks like a muffin 👌

  • Madhvi says:

    Oh my god! This was so perfect and indulgent. I am so happy after eating it. This is going to be my go to pms craving killer. Thank you!!

  • Savanna Atwood says:

    I love the thought of this mug cake, but when I made It it was not sweet at all. It tasted like the dry ingredients minus the sugar lol. I triple checked the ingredients to make sure I made It correctly and I also added chocolate chips. I most likely did it wrong, so I’m not bashing just thought I would share my feedback. If it worked for you please let me know what I did wrong. I will deffinitly try to make it again with some more sugar.

    • BG says:

      This came out beautifully when I made it. If you love Chocolate, you would love this, as I did. When I made it the second time for my husband, I added another tbsp. of sugar, to make it more sweeter.

      • Mishipiku says:

        I agree! I probably should’ve taken that extra tbs of sugar but the cake itself wasn’t sweet enough for me. Topped the whole thing off with powdered sugar and another tbs of hazelnut spread and I was all good to go :)

  • Faith says:

    Used almond milk instead of regular milk but followed all of the other ingredients to a T, microwaved for 90 seconds. Honestly best mug cake I’ve ever made, so moist and chocolately! Also love that it doesn’t contain eggs as I don’t eat them. Thanks so much for sharing this! :)

  • Anna says:

    It was delicious! We substituted 2tbs of brown sugar, but the recipe was so simple and so delicious that it’s definitely in the “favourites” for a quick and easy dessert fix. Loved the texture and consistency

  • Emma says:

    This was the worst recipe I have ever used. The oil made it impossible for the cupcake to cook properly as there was too much of it. It took me ages trying to scoop the disgusting mix into the bin and wash it off my utensils. If anyone is reading this, please do not waste your time or ingredients making this! There are much better recipes out there

    • Michael Baumgartner says:

      It is fine it could do with more flavour? It taste it bit plain when you run out of Nutella, so the solution is to add more sugar and Nutella

    • Sonshine says:

      That was rude.
      Why bash it with such hate.
      You were one person out of how many?
      Butter would have been better and since you need other people’s recipes and can’t figure it out on your own how to tweak it….leave the hate in your own home.

    • Best Bakes says:

      Use butter instead! That works!

  • Teneeshia Taylor says:

    Totally satisfied my sweet tooth!!!! My daughter and I loved this after dinner treat!!!! Nutella for the win!

    • Teneeshia Taylor says:

      Just to add we used melted butter instead of oil too. Perfect perfect perfect!

  • liza says:

    it is a little salty but besides that really good! self rising flour worked just fine!

  • Kiki says:

    I had to microwave 900W 6min (maybe if I didn’t take out after each 1min it would take less). Added 2tbsp coconut sugar and rice milk and banana slices. Tasty.

  • Tyler McCormack says:

    I wasn’t sure at first, but this is actually a very tasty treat, nice and easy

  • anonymous says:

    looks like horse crap, tastes worse than it looks. :( 2/10 would not recommend

  • Emily says:

    Have used this recipe 3 times in the last week and the whole family love it. I made a few changes where I put it in for 1minute 20 seconds instead of 1minute 10 as suggested. I also put chocolate chips and a spoonful of Nutella in the middle and one on the top xx overall great recipe x

  • Humaira says:

    Finally a recipe that works! I am new to baking and tried a few mug cakes which always came out bitter. Turned out the baking powder element was too much for the recipe. Can’t believe how luscious this cake came out, especially with a few added chocolate chips! Heaven!

    Will defo be making again and also will try the vanilla cake :)

  • Su says:

    Not gonna lie, I thought I was going to be disappointed with its turnout because mug cakes are never as good as the real deal but I was wrong! IT WAS SOOO GOOD!!! Just the right amount of moisture and it was so easy to make. I’d add more sugar the next time and try swapping 1 tablespoon of oil with melted butter to cater to my taste. But it’s seriously the best mug cake recipe and I can’t wait to try the vanilla version :)

  • :() says:

    This is the worst mug cake I’ve ever had. The consistency is awful and it tastes terrible. Even chugging milk and drowning it in chocolate chips doesnt help.

  • Natalie Lohi says:

    They all claim to be “the best mug cake you’ll ever try.” Only this time, it’s TRUE. It really is the best one! Both the flavor and texture is perfect! I will use it as a base to experiment with an almond flour version for keto!

  • Emily says:

    I’ve tried many mug cakes and this recipe is the best by far. I have a 1500watt microwave and did 65% power for 70 seconds. The uncooked bits are delicious (like a lava cake) but can also be microwaved a bit longer if you prefer. Also, I had no baking powder so I replaced the 1/4 tsp of baking powder with 1/4 tsp of baking soda and 1/2 tsp of vinegar. Will never make another after this.

  • Christy says:

    Omg thank you!! Literally threw everything in the mug and stirred and it was perfection.

  • Tesalynn says:

    Not good. Won’t try again.

  • Cynthia R. says:

    Hands down, the BEST mug recipe I’ve tried! I put half a tbs of peanut butter in the center and sprinkled chocolate chips on top. Definitely will be making again very soon! I’ve got a 1200w microwave and heated for one minute. Then let it sit to cook/cool for 3 mins. while I finished the dishes. I wanted to eat guilt free 😁

  • Sara says:

    The texture is not good… it tastes like flour and cocoa, not exactly the taste I was looking for. Would not recommend and would not make again.

  • Amanda says:

    Really nice recipe! Only had soft brown sugar in the house so used that instead and ended up cooking for 1 min 30 seconds in a 900w microwave but it was delicious x

  • Heather says:

    I make this every time that I need to eat a small cup of emotions. Thank you – perfect little size (excellent with red wine!)

  • Amy says:

    Yum just made it! That was delish! I added white choc chips and peanut butter chips 🤤

  • Jacquelyn Rowberry says:

    My husband and I loved this! We used oil and two tablespoons white sugar and one tablespoon brown sugar and the Nutella. Microwaved it for 72 seconds and topped with a poof of whipped cream. Delicious! Rich and decadent and sharable. Thanks!

  • Anna Renee Kelly says:

    I didn’t have a large enough mug so I made this in a soup bowl and 70 seconds was the perfect cook time. The cake was moist and super-chocolaty. Simply put, it was delicious!

  • Kayla says:

    This was the worst cake in a mug I’ve ever made it was so spongey and gross I can’t even explain it imma stick to the ones with eggs in it, that one was way better. Horrible can’t even not rate it but -5

  • Sara says:

    I must have done something wrong. I adnit, the final soup-like product certainly tasted good, but it was… soup. And 2/3 of it overflowed sll over the microwave. :/

  • Crista says:

    Only other cake mug recipe I like more is YOUR VANILLA recipe! Delish!

  • Kari says:

    This is to die for!! I dropped two Andes Mints in and made it a mint chocolate “lava” mug cake. I’m never trying any other mug cake recipe again!

    • Julie Wampler says:

      ooo the andes mint sounds AMAZING!
