A quick and easy microwavable chocolate cake, for whenever that chocolate craving hits.

I can’t decide if this is the worst or greatest idea I have stumbled upon— a chocolate cake, baked in a mug, in a microwave, in under two minutes.

You can go from hankering to satisfaction in a matter of mere minutes. It’s dangerously wonderful.

This recipe was originally posted in March of 2012. I wanted to update the photos, as well as address some of the issues a few of you had with the recipe. I’ve changed a few ingredient ratios, and made it into two mug cakes instead of one. The result is a chocolate cake that is lighter, tender and more moist, and still with a layer of gooey melted chocolate at the bottom that makes a wonderful stand in for frosting.

And now there’s cake enough to share!

What is Self-Rising Flour?

Self-rising flour is all-purpose flour that has a leavening agent— baking powder— and salt added to it. I don’t often bake with it, but it is perfect for recipes like this where so little amounts of each ingredient are required.

If you don’t have self-rising flour, you can substitute 1 cup of self-rising flour with 1 cup all purpose flour, 1 tsp baking powder and 1/4 tsp salt.

Two Minute Chocolate Mug Cake
A quick and easy microwavable chocolate cake for when you need a chocolate fix. This recipe was originally posted in March 2012. Slight changes have been made to the recipe.
Yield: 1 large mug cake, or 2 regular-sized mug cakes
  • 2 tablespoons vegetable oil
  • ¼ cup (60 ml) whole milk
  • 1 large egg
  • ½ teaspoon vanilla extract
  • ⅓ cup (40 grams) self-rising flour
  • ¼ cup (50 grams) sugar
  • 2 tablespoons (10 grams) unsweetened cocoa powder
  • ¼ cup (43 grams) semi-sweet chocolate chips
  1. In a small bowl, whisk together the vegetable oil, milk, egg and vanilla. Add the flour, sugar, and cocoa and whisk to combine.
  2. Divide the chocolate chips between two medium microwave-safe mugs. Pour batter into the mugs over the chocolate chips.
  3. Microwave on "high" for 90 seconds. Check to see if the cakes are puffed and bounce back after being lightly touched. If not, microwave for an additional 30 seconds. Serve immediately.
Note: If you don't have self-rising flour, you can substitute for ⅓ cup all-purpose flour + ¼ teaspoon baking powder + pinch of salt.

  1. When I was in college, my roommates and I *always* used to make these on late study nights–I’m so glad to see them get their I-need-dessert-now place in the sun!!

  2. When I saw this (or a similar recipe), I got hooked instantly for all the reasons you cited. It was so quick and easy. Because I wanted additional flavor options, I just forged ahead and created them. You can find some sample recipes for free at my web site, http://www.microwavemugcakes.com. I also penned a book called “101 Recipes for Microwave Mug Cakes” that might be of interest to you. I’d be glad to send you a copy for potential review in exchange for your address. Best, Stacey Miller

  3. I have a feeling you are going to make this for your little one over and over again through the years and you are going to be considered “the best mum ever”. Such a fun idea!

  4. Deborah says:

    I crave cake way too often – so this is super dangerous!!

  5. Heidi @ foodiecrush says:

    Smudge is going to love this, and I might love it even more because she can make it herself!

  6. Mindy says:

    Wow, this is going to be a problem for me. In the best way ever.

    • Anon says:

      You’re probably a 600lb bully who needs to be rude online to feel good about herself. Go get a day job or go on a jog instead of making microwave cake and then making fun of others for doing the same.

  7. Erika Beth says:

    Yum! I too have seen these recipes on a lot of fod blogs but haven’t tried it yet. It DOES seem like such a lovely way to eat cake quickly!

  8. could it get any easier than this? Looks SO easy and I love the quick “bake” time. :)

  9. Valerie says:

    Mmmm! A few months back I tried making a truly single serve version of one of these beauties. It was too small for me! I should definitely try this 1 or 2 serving version. ;) I love your measure, mix, enjoy pictures.

  10. marie says:

    I JUST made it! It worked! fluffy and moist. I didn’t have any chocolate chips, but I think it would have been tastier with them. It was also a little egg-y for my taste..not undercooked, what I mean is it tastes vaguely egg-y..like one of those egg doughnuts you can buy…all in all, my brother, dad, and I approve! :D

    • Annalise says:

      Perhaps next time only use half of the beaten egg and see if that’s more to your liking. So glad you tried it, it’s a dangerous dessert, isn’t it?

    By my calculation, the Nutrition Facts for this one mug cake are:
    782 calories and 50 g fat.

  12. beckie says:

    Im eating this amazing cake as i type. A-mu-ha-ZING! Luuuurv it :D

  13. Jill says:

    I just made 2 of these for my chocolate-loving son & husband! I added cream cheese frosting, too, which I always keep on hand. Mmmmm! Side note, my elderly father has many medical conditions, can’t eat much through the day, and usually only sweets appeal to him. I gave my mother this recipe & she will make it daily for my father. The calories will be good for him! Yum! :-)

  14. Becca says:

    Legit the best chocolate cake I have ever had. I added a smidge of instant coffee and hazelnut syrup only 3 sugar and just egg whites. Was fab

  15. Rebecca says:

    Just made this and it came out wonderfully! Substituted skim milk for whole milk and it was great, but otherwise stuck to the recipe. I split it between two teacups and it was the perfect amount for two people! I used mini chocolate chips and it was a good call for the smaller portions. Delicious!

  16. Amanda says:

    Honestly, I rarely comment on recipes. But this cake was the best mug cake I’ve ever tried and I’ve tried many. The powdered sugar on top makes it even better.

    Only had almond milk on hand so I used that instead of whole milk. Found this recipe last night…made it twice since! This is dangerous

  17. Chris says:

    Pretty good, I see what they mean about “eggy” it is a bit spongey, but it isn’t bad. Next time I’ll take the advice and use half an egg, maybe only a yolk or white to see what happens. But for those of us who like eating brownie batter, heck, just eat it without cooking it, it tastes like box brownie batter!

  18. Cassie says:

    I halved the egg and it still tasted egg-y to me. But I also am sensitive to the taste of eggs. All in all, maybe 1 1/2 teaspoons more cocoa and allllll good.

  19. palwasha yasir khan says:

    This was the easiest recipe ever!
    I made it at home just after dinner , it barely took ten minutes including prep and microwaving time! It came out awesome!
    I used a small portion of a chopped hazelnut chocolate bar instead of chocolate chips.it was so yummy!
    Thankyou so much for this awesome recipe!
    I love the pics you put up!

  20. Lea says:

    Any advice abt cooking times & microwave power?

  21. sara says:

    Thanks for this post. I made this tonight – first time microwave cake making adventure. I only used one tablespoon of oil, used skim milk, and flip-flopped the amounts of dark cocoa and sugar (so 4 tblsp cocoa and 2 tblsp sugar). I microwaved for 2 minutes @ 80% power and needed to do about 40 seconds more on high power. It turned out great for me but I would probably stay closer to the recipe if making for the adorable husband or others. Fun recipe to play with though – thanks again!

  22. Aleisha says:

    it turned out real rubbery and yuck i would not make it again

  23. Aleisha says:

    well i wold make it again but this time i didn’t use all the ingredients we didn’t have chocolate and coco but i tried to make vanilla but it turned to rubber but still eatable it didn’t eat it all but my dad did lol well i will try ti next time but with all the ingredients if i remember.

    • Annalise says:

      Thanks for the comments. The mug cake recipe as I’ve listed here (I haven’t tried any substitutions or variations, sorry) isn’t a perfect cake, but it definitely will fix a chocolate craving in a hurry. For me it’s a perfect last-minute weeknight treat.

  24. meenu says:

    tried this..came out delicious,soft and spongy..thanks a lot dear..

  25. sarah says:

    it looks nice in a way

  26. Patricia says:

    This was really good. I used butterscotch chips because that was what I had. They didn’t sink to the bottom, though. I also used a taller drinking glass. It was easy and fast and satisfied my chocolate craving!

  27. Angie says:

    This recipe is so good! My friend gave me all of the dry ingredients in a jar for Christmas with a list of the wet ingredients to throw in and it was literally one of the best chocolate cakes I have ever had. It was just like a lava cake; moist chocolate cake with a fudgey sauce inside. Bliss!

  28. R says:

    This was delicious…but when I did the nutritional facts for it I was really shocked! 841 calories and 42 were from fat. Luckily I split it with my daughter. Good for a once in a blue moon splurge…but be careful with these. They are addicting. :)

  29. Alex says:

    So good! Any idea if this recipe would work in the oven?

  30. Someone shared this in #foodfeed yesterday and I was reminded of this yummy post. Might come in handy when I need a sweet fix after the baby comes :)

  31. Arie says:

    It was awesome. I made it dark chocolate by adding a half tbsp of cocoa, and I used skim milk.But I didn’t mix the egg whites enough and I ended up with chunks of egg white in it. It was fine, but kinda weird. But I’ll definitely try it again. And I’m 13 if you wanna know how easy this is.

  32. Lacey says:

    The flavor was that of chocolate cake, but the texture was not. It was very spongy, and not enjoyable. It was like eating undercooked (chocolate tasting) French toast. I would not make it again.

  33. Liz says:

    This is even better if you substitute buttermilk for the whole milk.

  34. Jing Wen says:

    Can I use the self-raising flour instead of all-purpose flour?
    It looks yummy,I’m gonna try it soon ! :)

  35. Saara says:

    My family liked it wayyy more than me, probably since I have a slight aversion to eggs. Could you tell me something to use in place of the egg?

  36. Hi,
    My sister was recommended this recipe from a colleague. We tried it tonight and it was delicious. THANK YOU!

  37. Khajina says:

    I tried this yesterday, but I didn’t mix it well enough so it didn’t taste right!! Make sure to mix really well!!

  38. Meena says:

    Thanks Anna, made this quick and wonderful cake to surprise my sweet daughter for valentines day. She loveddddddddd it. THANKS

  39. Annalise,
    This looks delicious. Pinned.

  40. Cathy says:

    Found your recipe doing a google search and I just had to say that this is the BEST tasting chocolate mug cake recipe I’ve tried yet! Mmmm! Thank you!

  41. catlady says:

    Not sure where I went wrong. Had no powdered cocoa so I substituted for chopped baking chocolate and took out 1 tbsp of oil. It came out of but was the texture of bread pudding which is odd considering it should be chocolate cake lol any advice? I will definitely try again with proper ingredients. All the reviews are too great not to!

  42. Kelly says:

    Oh my goodness, yum!

  43. Emily says:

    Oh these are devine!! I used cake flour and a pinch of baking powder in mine though. Perfect light fluffy texture.

  44. Lisa says:

    Excellent recipe. I expected nothing and I got a great cake! I used a small egg, I think a larger egg would have been fine for me. Next time I will add more chocolate chips because I love chocolate!!! Thanks for sharing.

  45. Wendy says:

    This is the best mug cake recipe I’ve tried. I used skim milk and a splash of hazelnut syrup. Didn’t have chocolate chips, so I dropped a marshmallow in the bottom of each cup, and that made a great upside down frosting effect.

  46. Meghana says:

    Made this for my husband n myself on a rainy evening.. Rain n warm quick chocoalte was just amaaaaziiinngg..!! Loved it..

  47. Sharon says:

    I made this for hubby and I ….but I put a scoop of Nutella on top of cake mix instead of choc chips on the bottom and omg it was awesome :) thanks for such a great easy n quick recipe

  48. LeeAnn says:

    I have an ancient microwave and cooked two mugs for 99 secs, then 20 and then 20 again to get them fully set. They were a bit oovercooked and rubbery by that point :( But still delicious! Then I realised that I forgot to add the oil! Oops. I am tempted to get some powdered milk and eggs and make up emergency cake packets that only require a bit of oil and water, a mug and a microwave. As another commenter mentioned, they would make great gifts!

  49. LittleChaf says:

    Cool but It’s just a cake. I thought the chocolate is moist

  50. Ria says:

    I omitted the egg, lessened the sugar and oil (did 1.5tbsp sugar, 1.5tbsp oil) an it was soo good :D

    The cake was moist for me. Will definitely make again

  51. Danielle says:

    made this two nights in a row :)
    Used skim milk because that’s all we have, and used butter and chocolate chips instead of oil and cocoa powder (since we didn’t have any in the house).

    I nuked the butter and 2tbsp of choc chips in the microwave to melt them then followed the recipe- I did add a dash of salt and cinnamon, and did not put any whole choc chips because I don’t like things too sweet. It was perfect :) No eggy taste- maybe because I used butter? I used two mugs and it was perfect for my and my daughter :)

    Just adding my 2 cents in case someone has limited ingredients like me, and wants to know if it’s worth trying.

  52. Mary Bloomy says:

    Just tried it and I’m in love!! Amazing recipe! :) xx

  53. Jane says:

    Tried it twice .. it was awesome… :)
    I made a few changes 2nd time i made it… Do try and let me know how it is. :)


    Whole wheat flour / oats flour – 2tbsp
    Sugar – 1 tbsp
    Nesquik powder – 2 tbsp
    Baking powder – 1/2 tsp
    Instant coffee granules – 1/2 tsp
    Egg – 1
    Milk – 3 tbsp
    Olive Oil/ Vegetable oil – 1 tbsp

    An healthier and more chocolatey mug cake is ready. Serve it with a scoop of vanilla icecream or garnish it with chocolate flakes… Yummyyyyyyy !!!!!!!!!!!

  54. Naomi says:

    This is what I’m looking for, a 2-minute microwave cake. YUM!

  55. Kay says:

    Mine was rubbery, like pancake in a cup. What did I do wrong?

  56. Sommerlover1754 says:

    I made this with my kids and they loved it it tasted sooooo good I would definetly try this recipe again for a cake that can be baked in the microwave. I made this recipe to try out for the Christmas dessert at my Sisters house for a Little suprise. I would also make this for any regular dessert at anyone’s house even my own house and for birthdays. You can do so many things with this and just do anything you like with this

  57. Boomdog02 says:

    This looks really good when that chocolate jones kicks in….I really want to make this tonight after seeing those awesome pictures…oh, the heck with it, who am I kidding? I’ll just jam 2 big gobs of Nutella in my face and call it a night!!
