3 Ingredients, 60 Seconds: Gooey Chocolate Mug Cake

By Brooke McLay |

It’s Monday.  You don’t have time for chocolate, right?  Wrongo.  No matter what time of the day your chocolate craving hits, you’re just 55 seconds and three ingredients away from your own, personal mug full of the richest, chocolatiest hunk of cake ever.  Created one afternoon while in the fits of a crazy-mad chocolate craving, I attempted to mix togther the three vital ingredients for my favorite Chocolate Lava Cake, popped it in the microwave, and had my kids drooling all the ‘miracle mug’ one minute later.   It cooked up thick and full of deep chocolate flavor.  It made the kitchen smell divine.  So, I shared that first mug.  But, later, when the kids were tucked to sleep, I  mixed together another mug and ate it while watching the Bachelorette.  I might have done it the next night.  And the night after that, too.   I might still be doing it.  Because, seriously.  Three ingredients, sixty seconds.  Who doesn’t have time for chocolate cake when chocolate cake is that quick, easy, and scrumptious?!

Gooey Chocolate Mug Cake

1 egg

1/4 c. powdered sugar

1-2 Tbsp. cocoa powder (depending on how chocolatey you want your cake)

1 standard-sized mug

In mug, crack egg, add powdered sugar and cocoa powder.  Whisk together with a small whisk until well mixed.  Microwave for 50-60 seconds, until the cake is cooked through (but not overcooked!)  Top immediately with a handful of milk chocolate chips, hot fudge, whipped cream, or ice cream.  For PURE BLISS, my kids and I particularly love to pour several tablespoons of heavy whipping cream over the cake, then eat it with a spoon.  Divine!

    OMG. If this works how you say it will, I’m never buying brownie mix again! Can’t wait to try it but have to wait til the boys eat dinner!

  2. rick stedman says:

    this isn’t even a thing

  3. monique says:

    I am definately gonna try this tonight.

  4. mangiabella says:

    this is emergency cake! i love it!!

  5. danielle & clara says:

    me and my roommate tried this and I think we failed… ours tastes like chocolate eggs

  6. julie & Shera says:

    We tried this and it was pretty darn tasty! We added a few pinches of salt for added flavor and also a couple teaspoons of regular sugar on top of the powdered. Mixing completely is key and then it is melt in your mouth chocolate decadence delicious!

  7. Raena says:

    I must say, I was quite skeptical when I read the short ingredient list. I thought you at least had add flour to make a cake….WRONG! The cake turned out EXCELLENT! It rose to the middle of my mug, and it had a warm chocolatey center. I used cocoa powder as well as ground chocolate. When it was done I threw a few chocolate chips ontop! WOW!

  8. Rachael says:

    Well, its not gooy brownie and its a wacky cake texture, but its not bad for pinch. I didn’t have cocoa power, so I grated unsweetened chocolate powder to a fine state and used that, Perhaps that resulted in my fun texture? Anyhoo, not bad, but if you are a die-hard brownie fiend, it might not do!

  9. Chelsea Terrell says:

    I made a double batch (I had a really big mug) and did if for a whole minute, and it still turned out great. I had even instead of using powdered sugar, used regular sugar grounded in a coffee grinder, and it puffed up and everything. Typically I have a very high threshold for chocolate, but this was deferentially chocolaty.

  10. Ella says:

    I think that even at 50 seconds there is a potential for it to be overcooked. However, it DOES work. I recommend Vanilla Ice Cream on top.

  11. Jelika says:

    This actually works–its not WONDERFUL, but for dessert in a pinch? Genius.
    Do not be deceived by the burnt smell when it first comes out–from what I’ve found, it works perfectly. Try whipped cream :d

  12. Rebekah J. says:

    I tried this, but I didn’t have cocoa, so I used Nesquik chocolate milk powder instead. It actually turned out okay, because i like the taste of it.

  13. polo66606 says:


  14. Taylor says:

    it tastes like ass and chocolate egg…. nasty

  15. april says:

    hey do you know any nutritional facts about this??

  16. carly says:

    VERY rich, yummy yet satisfying. I believe its approximately 350 calories depending on how much cocoa you use. But i love this recipe i will definitely share this with others!

  17. Jessica says:

    I tried making this twice with a different amount of ingredients and cooking time the second time and they both turned out gross! =/ The second time wasn’t as bad but it still had a gross texture..I guess 1 minute chocolate cake IS too good to be true after all..oh well..not like I need it anyways lol

  18. DJ says:

    Yummm! Can’t wait to try it!

  19. chanel says:

    i got really desperate for this and used mint cocoa powder mix instead (didn’t have just regular) and it is DELICIOUS. i topped it with a tsp of peanut butter and i’m truly in love. genius!!!

  20. Elisa says:

    I used cocoa mix because that is all I had and it worked great. I also crumbled an andes mint on top! Delicious!

  21. Alyssa says:

    You seriously have to be careful about over-cooking. It pretty much needs to be well under-cooked for it to be gooey. If it is well-done at all, you’re going to find yourself eating cake, mixed with what is almost like the consistency of hard boiled egg. I’ve made this three times, the first time it was AMAZING (i cooked three mugs at once) and the other two it was horrendous (i cooked one mug those times).

  22. kaylajo says:

    wonderful idea as soon as i found this i tried it and it was amazing i drizzled a little carmel on top and was in dessert glory!!!

  23. pnoo says:

    Didn’t quite work out for me. I went by the recipe exactly (2 tblspns cocoa powder) and it came out…….. strange. It seemed a strange consistincy and it was a bit overcooked in some places and undercooked in others. The taste was flavor-lacking in some parts and too chocolatey in others. It was just very inconsistent. A mixing problem on my fault perhaps?

  24. Gigi says:

    Made it tonight — YUM!! I mean, it’s not the best cake you’ll ever eat, but for 3 ingredients, NO flour, and 1 minute in the nuke box, seriously — this is a great dessert. Especially for gluten-free people (like moi), though of course that’s quite a bit of sugar. It’s a great “in a pinch” dessert. Topped mine with whipped cream. Thanks for the idea!

  25. Hannah says:

    Fab! However I added a bit too much cocoa powder which turned it slightly bitter. Nothing a few scoops of ice-cream couldn’t remedy!

  26. katy beth says:

    these people are crazy! this cake is sooo good:) it will never replace a cake out of the oven, but it’s a fantstic single serving! i added some mini chocolate chips to the cup and topped it with whip cream. delicious!

  27. Haily says:

    I tried to make this and it didn’t turn out as well as I had planned. The egg was not well mixed, even though I mixed it for a while to make sure. It tasted like a big old chocolatey egg. Eww.

  28. Melissa says:

    wrong on SO many levels… ;-) thank you for sharing!

  29. Lis0r says:

    What is the wattage of the microwave you used? This would help with figuring out the appropriate timing! :)

  30. Pat says:

    This is RIDICULOUS good! I thought for sure that you would need flour, but I was wrong. This is delicious! I’ve made it quite a few times and people think it’s amazing. Try it with sliced strawberries and whipped cream too!

  31. Vanessa says:

    Just made this and it turned out pretty dang awesome! Like people have said, it’s not a cake from the oven, but is great for then the chocolate attack hits. And I’ve talked myself into thinking it’s kinda healthy – no flour, protein-filled, and a small-ish portion. lol

  32. Marsha says:

    1/2 tbsp of brown sugar Splenda
    2 tbsp dulce de leche cocoa mix (from World Market)

    Mix in a mug and nuke it for 1 minute. My microwave usually needs another 10-15, but I check it after a minute anyway.

    Very yum.

  33. Catherine says:

    I made this for my roomate and I and it turned out great! It’s the perfect dessert for college students and SO easy to make. The key is to really mix the ingredients well and DON’T over cook it!

  34. Lance says:

    Absolutely delicious!!

  35. rachelle says:

    i read this recipe and ran to my kitchen…i have been craving chocolate for days, but i’ve been too lazy to go to the store :D

    i sent my kids upstairs to play and i enjoyed the cake by myself! *evil laugh*

    i topped mine with hershey’s syrup and some milk!

  36. chris says:

    this has the texture more like a fondant than a cake, so that might be why some people think it tastes like chocolate eggs. it’s still good though. i microwaved mine for 30 seconds, cracked the top and added a spoon of low fat peanut butter in the middle, and then microwaved for another 30 seconds. once it cooled, i topped with some marshmallow fluff. super yummy quick chocolate fix!

  37. KaydeBugsMommy says:

    I microwaved mine for 55 seconds, and it kinda had a weird texture- probably got it a little over done! It still tastes amazing, though, and I will definitely make it again!

  38. cait. says:

    this is going to KILL my waistline, haha, but as a college student, this is a perfect solution for a late night chocolate fix. just make sure to mix well & don’t overcook.. i put mine in for 60 seconds & the texture was funky. however, it tasted awesome. for a quick mug cake recipe, this is great!

  39. Ali says:

    this really works! the key is mixing it well – be careful not to get the cocoa powder everywhere – but mix well until it looks like brownie batter. Then cook :)

  40. Kaitlyn says:

    So so so good. I’ve tried several mug cakes lately and I just keep coming back to this one! I think I’ve perfected it:
    Use the same measurements for everything, but ONLY use the egg white, not the whole egg. And add the chocolate chips before hand and only microwave for 45 second. When you pull it out of will look underdone but it’s perfect! Fudgey and gooey and delicious. So good I really reccomend this.

  41. angela says:

    this is the most dangerous thing i’ve ever learned. ever. it works. if it doesn’t work, you’re doing it wrong. i used regular sugar, added a little salt and vanilla. it’s like the dessert brownies in the microwavable frozen meals.

  42. yo says:

    i mixed REALLY well, added a pinch of salt and eyeballed about 1/2 t. of vanilla and then only nuked for 45 seconds. it looked kinda like chocolate mousse, with lots of air pockets, but i could flip it upside down in the mug, so it was solid, with a thin coat of liquid at the bottom. wasn’t sure if it was cooked enough, but by the time i go the kids ice cream and then topped mine with ice cream, i think it had a little extra time to self-cook and it was fine. not perfect, but satisfied my craving!

  43. Jill says:

    I added about 2 drops of mint extract and threw an Andes mint on top. Wow. I’m glad its just mug size, otherwise I would be eating a whole pan! Delish! (I made sure to microwave 50 sec & used 2 T Starbucks coco and a dash of salt)

  44. marie says:

    Have you ever seen a grown man blow chunks? This is what happened when i took it out and my dad smelled it… smells like wet dog. I rate this * one star.

  45. Emily says:

    I have no idea what the people who are complaining are thinking. This is delish! I beat the egg with a fork in the mug & then added the powdered sugar and the cocoa (1.5 tbs) . Mine turned out fabulous at 1:15 in the microwave. My microwave is a bit weird. Anyway, the smelled slightly burned when I took it out, but tasted amazing. Seriously, thank you so much for this recipe. Great emergency chocolate recipe. (:

  46. missy says:

    It looks like a wet cupcake and tastes worse than it looks… Maybe it needs some doctoring up like vanilla or regular sugar like some other commenters suggested… but at my first attempt, I am unimpressed.

  47. Marissa says:

    This came out a little dry the first time I made it, so I added a scoop full of plain Greek yogurt the second time and it came out delicious! Added just enough creaminess to balance it out!

  48. Karen says:

    I have never heard of this and such simplicity. I went and tried it and decided to add a teaspoon of peanut butter. Came out excellent. My teen 17 yr old boys love it. I will be making again.

  49. Diana says:

    Try using egg whites to cut out the eggy taste! its delish. This is a mug cake keeper =) thanks!

  50. hi says:

    Yeah smells like wet dog.

  51. Elizabeth says:

    Tried this recipe and it tasted awful. Seriously, it tasted like a hot, soggy sponge. I don’t know what I did differently than the people who got good results, but I don’t think I’ll even bother trying this again. Disgusting!

  52. bethany says:

    For those of you disappointed with this recipe, here is the one I use. Its not as simple, but it is more like a cake:

    2 tbsp cocoa powder
    4 tbsp sugar
    4 tbsp self-rising flour
    3 tbsp oil
    3 tbsp milk
    1 egg

    Microwave for three minutes.

    I mix mine in a bowl because I do not have any large mugs.

  53. Adriana says:

    Just tried this didn’t like it too much it was too eggy for me. It tasted a little off. I used nesquik instead of cocoa powder cause I didn’t have any tasted just like chocolate anyway I probably won’t make this again unless I figure out what to do different no my favorite recipe though sorry

  54. Michele says:

    Followed the direction exactly and it was terrible. I also tried the chocolate salted caramel cake and that was even worse. I think if it had some chocolate chips it would be better but I haven’t tried it yet.

  55. ariel says:

    can it be the drink cocoa powder?

  56. CreativeDiva says:

    Have spoonful of nutella ready when it comes out. It will get soft & melty, then a dab of whipped cream & you’ve got a winner. Trust me. It was yummy!
