The Moistest Chocolate Mug Cake


The moistest chocolate mug cake you will ever have! It's not spongy like other mug cakes! Recipe on

Holy bananas, you guys. It has been FOUR YEARS since I first developed this chocolate mug cake recipe. Omg, it seriously feels like just yesterday. Ever since then it has broken the internet. Well, not really, but it’s the most popular dessert recipe on my site to date — for good reason!

I’m revisiting this mug cake post specifically today because 1. I have a recipe video that goes with it now (check below right above the recipe!), 2. I cannot believe the response on this mug cake, and 3. if you’re into Valentine’s Day — wouldn’t this be the perfect dessert for you and that special someone??

The simplest dessert yet incredibly moist, easy, and the best single-serving dessert out there (to share or not to share)!

You likely have ALL the ingredients in your pantry already. When you get that late night craving? Or want a small batch dessert (and not whip out a giant baking pan to make brownies to nip that craving)? This chocolate mug cake IS FOR YOU!! If you haven’t made this yet; you are 100% missing out.

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.

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 :)

I mean seriously. How could you not want to drop everything and go make this immediately?!

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!

Course: Dessert
Cuisine: American
Servings: 1
Calories: 606 kcal
  • 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
  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 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! :)

  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.) 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.

    This is not chocolate mug cake, this is heaven in a mug.

    Step one: Follow the recipe, up to the point where you pour the batter in the mug.
    2. Add chocolate syrup
    3. Mix
    4. Add more chocolate syrup, as well as tons of maple syrup (No, I’m not a crazy canadian. I’m a smart canadian.)
    5. Microwave, and enjoy hot with more chocolate syrup, topped with ice-cream of your choice, along with a heap of whipped cream.

    Don’t judge me. I’m an 85-pound 14 year old. I can afford to eat unhealthy.

      Sorry, this is an American-based blog so that’s why I have it in cups. There are converters online that do this for you. A quick Google search would pull some up.

    Thanks so much for this recipe, it’s moist, rich and really chocolatey! I always use good quality cocoa like Droste and marvel at such a nice texture could be achieved in the microwave. I’ve made this recipe a number of times and always enjoy it. It’s so perfect when you’re craving yummy cake and know baking a whole cake is a dangerous idea. It’s fun all the different ways you can modify it, tonight I made a s’mores version by added some cinnamon with the dry ingredients , then a dollop of marshmallow fluff after mixing, and after cooking added a crumbled graham cracker.

    The first time around i forgot the baking powder and the vegetable oil overpowered the chocolately goodness.

    Second time around I used coconut oil instead and drizzled chcolate syrup on top and it was heaven!! Thank you so much for this cute little chocolate cake for those late night cravings!

    Just prepared this in a flash, to calm down a Sunday night craving. It’s perfect, just “as advertised”. I finished it with a little bit of dulce de leche on top. Thanks!!

    This recipe is a very good one. I agree that the egg in a mug cake recipe makes it spongy. I did alter it a little though. Instead of oil, I replaced it with 2 tablespoons of melted butter that I just melted in the mug before adding the other ingredients. Also, even though I had cocoa, I replaced it with an individual package of cocoa mix w/ marshmallows. I was out of chocolate chips which I usually include in my mug cake ingredients, but the marshmallows in the cocoa mix added nicely. Happy dessert : )

    Hi there, it’s us again. we’ve been looking through the comments and seeing that a lot of people are using butter/ coconut oil instead. what do you personally recommend as an alternative as I am allergic to vegetable oil. many thanks!

    • Julie
      07/06/2018 at 8:09 am

      I would definitely use the coconut oil or butter!

    This was one of the best mug cakes I have every had. I recommend making this when you just want a delicious cake.

    This is awesome. Hubby & my new favourite. I make up a few little snap lock bags of dry mix so I only have to pop it in a mug with the oil & milk ( & Nutella)

    Love this. But instead of using all purpose flour I ground up some old fashion oats and used that as flour. I also used cane sugar instead of the sugar you used. I topped it with chocolate syrup and whip cream. My only question is I put it on the time you said and it didn’t cook ok the way I add another 30 seconds and the bottom still isn’t cooked all the way. Any advice??

    • Julie
      07/12/2018 at 4:13 pm

      I guess I would say it totally depends on the type of mug you used and probably how dense the batter is b/c of your substitutions.

    Hello, I’ve just finished eating a delicious choc mug cake made by my 9 year old. We were just talking about how easy it was to make and how it has cured many a choc craving in our household (been making it for a year or so) and I thought I should let you know! Thank you for your simple and delicious recipe!

    Anyone else find this overly salty??? I followed it to a T :(

    • Julie
      07/12/2018 at 3:56 pm

      1/8 teaspoon of salt is barely anything for this recipe so i’m confused as to why you found this super salty. did you use baking powder or baking soda? did you change anything else in the recipe?

    This Chocolate mug cake is absolutely delicious, easy to make, and also very quick and simple, I definitely recommend using this recipe as it is just amazing, me and my friend loved making this and I’m pretty sure you will too!

    This recipe was so fun to make! I ended up chilling the batter for 15 minutes or so before microwaving it. I put it in for around a minute and 20 seconds (my microwave is 900 Watts). Overall I think it turned out great! Thank you for the recipe!

    I made this again tonight and found that 70 seconds was perfect. I always make this in an oversized mug, so there’s no spillage (loss of chocolaty goodness), and add a dollop of peanut butter on top of the chocolate chips before baking. It’s a not-so-wee bit of heaven right here in my kitchen! Thank you for sharing. I always promise myself that I’ll take a photo before I eat it, but I can’t help but dig in right away, lol.

    Really enjoyed this, best chocolate mug cake recipe I’ve found so far! Next time I will divide the batter into two mugs or cut the recipe in half though because it was a bit too much for just me. I topped mine with a little powdered sugar as well.
