Step 1: Supplies

Picture of Supplies
TOOLS:

INGREDIENTS:
  • 4 tablespoons flour - make sure you measure it right - or the cake is a lie!
  • 4 tablespoons sugar
  • 1 tablespoon unsweetened cocoa
  • 2 tablespoons whisked egg - 1 egg is too much, 1 egg white is too eggy, 1 yolk is too dense, but 2 tblsp is just right!
  • 3 tablespoons milk
  • 3 tablespoons oil
  • 3 tablespoons chocolate chips
  • splash vanilla or other flavoring - try peppermint or cinnamon
For a fudgier version, omit egg.

Step 2: Mix your ingredients

Picture of Mix your ingredients
  • Add all of the dry ingredients to the mug and mix.
  • Add the egg and combine well. It gets pretty pasty at the point.
  • Stir in milk and oil.
  • Add chocolate chips* and splash of vanilla. Stir well.
*if you don't have chocolate chips, try a broken up candy bar - I can't stress how much this amps the awesomeness of your cake

Step 3: Nuke It!

  • Microwave for 3 minutes in a 1000w oven, or 4 minutes in a 700w oven.
It will start to crown over the top of the mug. Don't panic! It will collapse once the heat stops.

Thank you!
I actually experimented with about 6 different variations of the recipe before I decided that this one was the best.

these things are optional


  • splash vanilla or other flavoring - try peppermint or cinnamon

For a fudgier version, omit egg.

yum! This recipe has come out great all three times I've used it. I love to add cinnamon, chili powder, nutmeg... whatever I have around.

I mix the batter in a small bowl and then pour it into two smaller oiled mugs and cook for about a minute.

In the picture below I added semi-sweet and white chocolate chips. Then melted a bit of the white chocolate and decorated the tops.

After some instant microwave cake disasters, this recipe came out great! I've tried a few microwave treats, and this was the only one that came out on the first try. It was delicious! It also looked like it needed frosting. We didn't have any, so I used chocolate sauce.
Thanks!

Oh, this is terribly dangerously DANGEROUS to know. :-) My mugs are pretty small, so I made this in a bowl, which required reducing the cooking time to about 1: 45. I omitted the egg for a fudgier result, and it's a wonderful cake/brownie hybrid. I chopped up 3 tablespoons' worth of Hershey with Almond bar, since it's all I had; I also made a glaze with about 3 tbsp. confectioner's sugar and just a few drops of milk. DAN. GER. OUS. It's incredibly rich and I'm not sure I'll be able to eat the whole thing, but dangit, I'm trying.
I made this recipe using 6 tablespoons of hot cocoa powder in place of the unsweetened cocoa and sugar. IT TURNED OUT GREAT!!!!!!!!!!!!

I'm playing with your recipe, for one very important reason: I'm a Weight Watchers member, and the recipe as you wrote it is 20 points (I have an allowance of 29 points per day + 49 extra discretionary points to use per week). That's more than I want to spend in one place. BUT the recipe is SO good, that I really want to fit it in to my program. So. A major portion of those points come from the oil (9) & the chocolate chips (3). I didn't want to completely eliminate the chips, but I could cut back to 1 Tbsp (1pt). And I cut the oil to 2 tsps, because I am required to have 2 tsps of oil daily. For the rest of the oil, I subbed--ta da! applesauce! Surprisingly, there was no difference in flavor, and the texture was still good! This knocked the points count down to 11, which I find a comfortable splurge evey now and again. Oh, and one other amendment? I a changed the 3Tbs of milk to 3Tbs of fresh-brewed coffee, for a nice mocha note. All in all, a happy dance for me! It also occurs to me that, for a nice nutty note, you could used toasted sesame seed oil.
I'm eating this right now... and I LOVE IT! I noticed someone else mentioned using a mashed bananna instead of oil so I tried it that way and used white chocolate chips... all I can think though is "this would be awesome with nuts". Not sure how well nuts would do being nuked. I also noticed other people mentioning the bottom of theirs being burnt and the top not being done. To make sure I didn't run into this problem I put mine in for 1 minute, then stirred it to bring the already cooked pieces up to the top so half of the cake wouldn't be burned. I also nuked it in short intervals (1 minute check and stir, another minute check, 30 seconds etc) to make sure it wasn't burning and also because i'm not sure how powerful my nuker is. When it was done I let it sit in the microwave for as long as I could stand (so the ambient heat would help cook anything that wasn't yet done without burning the rest). Mine didn't puff up out of the mug, but that could either be from the mug or stirring it after a minute of cooking. I think i'm going to try this again tomorrow and instead of a mug use a small glass microwave safe pyrex dish, I think that will help it cook evenly without having to stir halfway. Either way I can't wait to tell my mom-in-law about this she's gonna love it.
Tried it and it was excellent. Kudos for taking some very shady looking recipes from online and making it a sure bet!

bOOm! Or like the romans say: veni vedi vici - a total winner that lil' cupcake! Even I could do it - and that's nothing short of miraculous ;) I was able to use the microwave w/o causing radiationburns on the better part of northern europe AND got a super tasty result. I used 600 watts for approx. 4 mns - and YES - I will do it again... and again...and...

Cheers from germany,

That is truly a thing of beauty.
love this instructable, turns out awesome cake

i made one yesterday that rose to almost double the height of the mug, but was deflated by the time i got a camera. turned out nice and fluffy though

I experimented with this, and found that pudding mix works great! just substitute any pudding mix for the chocolate powder (and eliminate the chips, unless you want them in there). So far Ive tried strawberry, vanilla, and white chocolate. They tasted great

I also made vanilla butter cream to put on it and that was really good. I just halved the batch!

Should this be self raising flour? Mine did not raise using just flour....

I'm confused as to the purpose of the scale.

I'm almost afraid to ask this (afraid for my waistline, I mean) but… do you think you could incorporate peanut butter into this in some way? Like at the same time as the egg or instead of (some of?) the oil? Maybe someone's already tried but I can't find it in the gargantuan number of positive comments!

Make sure you experiment with your microwave for cooking times and power level, it's can be a little tricky to get it just right.

I've noticed :)

I'm sure this cake would have been delicious if not for my microwave catching on fire. Nothing's better than the smell of burning chocolate when baking. 10/10.

I also recommend turning the microwave off when smoke starts coming out. Beginners mistake, my bad. -.- (Sorry, this is about as positive I can get while my microwave is literally pumping out smoke while my fire detector goes off.)

I would add an image but I was too busy freaking out to take a selfie with it.

This was so good for a 5 min mug cake also perfect with whipped cream and nice on a Sunday night thanks for this awesome recipe

It tastes good for a 5min chocolate cake. Thanks for sharing

WOW! This turned out amazing, and I've made several 5 minute mug cakes before, and was happy with them, UNTIL I made this one about an hour ago. I added a pinch of salt with the dry ingredients, and right before I put it in my microwave, I added 1 Tablespoon of dark chocolate syrup and did NOT mix it in.

I baked it in y 900 Watt Microwave for 3 minutes and 40 seconds, which was perfect. I served it removed from the mug and put in a soup bowl, and put ice cream on it, the about 1/2 teaspoon of the dark chocolate syrup on top in a little swirl.

This is now the PERFECT recipe! I can't thank you enough for perfecting it!

This is my favorite "quick" recipe. As long as the measurements are exact, it's always cakey and not rubbery. If there is too much egg, then you get rubber. Also, you can always omit the egg!
temp_-1849046506.jpg

This didn't work at all for me. I have a 800W microwave and set it for 4 minutes (left out the egg as some otherh comments said it's not necessary), and when I returned to the kitchen, everything was full of smoke.... 4min was way too long.

Hi. As in the mood for just a little bit of chocolate cake earlier tonight. This turned out perfectly!! I added a little canola oil to the mug so cake wouldn't stick. That added to the moisture of the cake. Thanks so much for sharing the recipe.
