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.

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.

    I agree about many mug cakes… they just don’t do it for me. This one looks so good that I’d probably make it a little too often.

      Just made this but replaced the oil with butter OMG YUMMO!!! Me and my son are in heaven!

      • 10/21/2014 at 8:51 pm

        I just made it the normal way but next time I am trying it your way. Butter sounds divine.

      I have tried both the chocolate and the vanilla mug cakes. I LOVE them both. So moist and delicious. Thank you so much for sharing this.

    Wonder if I could just stop what I’m doing and make this right now? Lol! Looks great!

      This was GREAT! I never thought these things actually worked! I dropped a few chocolate pieces in the middle instead of nutella-worked great.

  3. 02/24/2014 at 8:43 am

    Chocolate cake in a mug in only 2 minutes, I’m so in!

  4. 02/24/2014 at 9:12 am

    This is fabulous. I love mug cakes! Especially since it only takes a few minutes to make.

  5. 02/24/2014 at 9:28 am

    I want to hug you for this! I’m always looking for something small to curb my sweet tooth. This is perfect! I’m trying it tonight!

  6. 02/24/2014 at 9:38 am

    I have to try this–STAT!

  7. 02/24/2014 at 9:43 am

    this mug cake look awesome- the dollop of nutella is a nice touch!

  8. 02/24/2014 at 9:53 am

    Mmmm!!!! I can’t wait to try it :)

  9. 02/24/2014 at 10:36 am

    What about one for a pound cake?

    • 02/24/2014 at 1:06 pm

      Hi Richard, pound cake in a mug is interesting! A very challenging proposition that I would consider trying sometime.

    This looks amazing! Any tips for lowering the calorie count? I love my chocolate but I love it even more when the calorie pay off is lower! But amazing mug cake!

    • 02/24/2014 at 1:05 pm

      Hi Eman, no tips here. I’m not a registered dietician or nutritionist so I definitely don’t have good tips that are clinically approved :) sorry!

    • Rachel
      04/06/2014 at 6:11 pm

      For some reason, the only thing I could taste in my mug cake was the vegetable oil. -sad face- Could I lessen the amount of oil, or would that mess with the consistency? I’m bummed out that mine wasn’t a success unlike so many other people’s!

      • Julie
        04/07/2014 at 8:06 am

        Hi Rachel, what a bummer. How old is your vegetable oil? I’m wondering because maybe that’s why you taste it if it’s old and gone rancid. You could try to lessen the amount of oil, but when I tried that, it wasn’t as moist of a cake.

      • Amanda
        05/02/2014 at 9:52 pm

        I thought the 2T seemed a bit excessive too, especially since an entire cake often only has 1/2C (8T).

        I just made it with about 3/4T oil and a dash of vanilla extract and it was still incredibly moist and delicious.

        My only complaint is that I didn’t have any Nutella or similar since I can’t keep it in the house for more than a few hours, lol!

      • Taylor
        05/31/2014 at 10:15 pm

        I tried it with veggie oil the first time and wasn’t thrilled with the texture or oily taste. If you’re not counting calories you can substitute 2 tbsp melted butter.

      • Caley
        06/04/2014 at 12:53 pm

        Personally, I like to sub in coconut oil in the place of olive oil and butter :)

      • 07/07/2015 at 4:15 pm

        Try replacing the oil with 1Tbsp apple sauce. It won’t rise quite as high, but its still delicious.

      I made my cake using Stevia instead of sugar, which helps at least a little bit with the calorie count. I don’t mind the slight change in flavor at all– it is the best 0 calorie sweetener (and not chemical!) I’ve tried. Just make sure to use LESS stevia than you would use sugar.

  13. 02/24/2014 at 11:24 am

    I have to have dessert with every meal and have yet to make a mug cake but really want too… I think this just might be dessert tonight!

  14. 02/24/2014 at 11:35 am

    OH MY WORD! I totally need to try this!! Bring on the chocolate.

  15. Diane
    02/24/2014 at 11:55 am

    I would love a vanilla or yellow cake version. Do,you have one?


  16. 02/24/2014 at 1:04 pm

    This looks wonderful! I am trying this ASAP. I haven’t found a mug cake I love so I am super excited to try yours out.

  17. Oh em gee! That spoon picture is killing me. I need to make this today, or I’ll be dreaming about chocolate cake.

    Julie, your chocolate mug cake looks amazing! Cannot wait to try this as I’ve had a raging craving for chocolate cake (and chocolate chip cookies!) since overcoming the flu and getting my appetite back. Thanks for sharing, girl. Will pin to group boards at Pinterest! xo

  19. 02/24/2014 at 2:22 pm

    Wow! it hasn’t any egg! gonna try it soon, gal! it’s on my Sunday list! :) & yeah love the pictures! :)

    • 02/24/2014 at 2:33 pm

      The egg is what makes most mug cakes spongy so that’s why I omitted it! :)

  20. 02/24/2014 at 2:35 pm

    aw. mah. gawd.

    The pictures scream “MOIST CAKE” and love the addition of the hazelnut spread! I have never made a mug cake before, I know, I’m a weirdo but this recipe will totally be my first and by the looks of it… I will NOT be sharing! :) Pinned!

    • 02/24/2014 at 3:39 pm

      Thanks, Krista!!! Haha, it’s made for one and only one so sharing isn’t mandatory! ;) thanks for sharing! xo

  24. 02/24/2014 at 3:23 pm

  25. 02/24/2014 at 4:00 pm

    I’m so glad that you perfected the recipe because this looks amazing! I all for a super moist mug cake, and especially one that is chocolate!

  26. 02/24/2014 at 5:18 pm

    I’ve disliked every mug cake I’ve tried, but this one looks perfect! I’ll have to try it!

  27. 02/24/2014 at 5:24 pm

    I am so NOT over mug cakes! Maybe I’m a little late to the game on these but I love the fact that I can make an individually portioned dessert in just a few minutes when a killer sweet tooth sneaks up…yours does look incredibly moist so I am definitely giving it a go!

  28. 02/24/2014 at 5:39 pm

    I live in a dorm so this is perfect! I’m out of Nutella, but I do have some dark chocolate I can throw in there. Thanks for the recipe!

  29. 02/24/2014 at 6:42 pm

    Yes yes yes yes yes! I approve 100%!

  30. 02/24/2014 at 9:04 pm

    This mug cake looks so tempting! Great treat in a good portion :)

  31. 02/24/2014 at 9:47 pm

    Done and Done! Just took my mug out of the microwave and taking my first bite. Delicious! And probably the quickest turnaround ever – from seeing the recipe to eating – for a dessert!

    • 02/25/2014 at 7:54 am

      Awesome, Liz!! So glad you loved this and already made it! :)

    02/24/2014 at 10:13 pm

    If I don’t have hazelnut spread what else do you think we can use? Do you think icing or chocolate chips would work well?

    • 02/25/2014 at 7:54 am

      Hi Maya, in the notes section I stated that you could use peanut butter or Biscoff or any other spread you’d like. Icing sounds heavy but chocolate chips would work great!

  33. 02/24/2014 at 10:50 pm

    So quick and easy, I think I need one right now!

  34. 02/24/2014 at 11:10 pm

    Thinking about getting up and making this now. It looks so good and I just finish dinner, so it is time!

  35. 02/24/2014 at 11:22 pm

    Will you please come over and make this for me? It looks amazing! Pretty please? Ok, nevermind…it looks too delicious – heading to the kitchen now! :-)

    Okay, Julie, this is just too easy! I blame you for the 10 lb weight gain I’m about to have since I’ll probably be making this every single day!

  44. 02/25/2014 at 12:58 pm

    I’m pretty much dead.

  45. 02/25/2014 at 1:30 pm

  46. 02/25/2014 at 1:30 pm

    I am SO making this for dessert tonight. I can tell from the photos that it has a heavenly texture. I also have a jar of Nutella in my cupboard, so you can bet I’m going to add a hefty spoonful!

  47. 02/25/2014 at 3:15 pm
