I have a 900w microwave. Did everything as said and it came out hard. Either needs more moisture or less cooking time!

It is really good- especially the top! A good suggestion is if u dont have any chocolate chips u can use add a crushed chocolate chip biscuit into the dry mixture and it will taste really good!

I used plain flour and added a good teaspoon of baking powder. It worked really well in 2 mins on 900w microwave but even in my biggest mug overflowed onto the plate. I will def make again but in a small pudding bowl next time. I agree it doesn't look a bit like the picture but with cream and fresh raspberries from the garden it didn't matter!

I made this with a few alterations and it turned out great! I used 4 tbsp of self raising flour rather than plain, 2 tbsp of soft brown sugar, 2 tbsp of sweetener and 3 tbsp of apple sauce instead of the oil. Did it for 3 minutes in a 700W microwave, it didn't have a molten centre, but tastes great!

Here is what I did..... MIXED 4 T flour, 5 T brown sugar, 2 T cocoa together in 'dry' bowl; MELTED 3 T butter in mug, STIRRED 3 T ice cream into butter; (i didnt have any milk) POURED wet ingredients over dry and ADDED 1 egg; STIRRED till blended well, ( i forgot to ADD drop of vanilla ) ; SPRAYED mug with cooking spray; POURED 1/2 mixture into mug; SPRINKLED 1 T chocolate chips then POURED rest of mixture on top. COOKED 1 min 10 sec on high ; DO NOT OPEN MICROWAVE! LET SIT 2 minutes to finish cooking. TOPPED with ice cream. This was awesome! not at all 'rubbery'. Mixture could be divided into 2 mugs as it makes plenty for 2 people.

Really good :) used self raising and cut time down to 2 mins....1.30 would have done it I think! Will use butter next time too as was a wee bit rubbery - but still amaze :)

Ha ha ha, who took that picture!! it does not represent the garbage that came out of my microwave! i followed it to the letter, i have a 1000 watt microwave and i was getting excited watching it rise over the mug. Opened it up, topped it onto the plate and it pretty much bounced off the plate! rubbery, hard, tasteless, YAKKY
Waste of my 5 mins :(

This recipe worked for me - a delicious quick treat with handy ingredients. I used half melted butter and half oil, and added 1/4 tsp baking powder. Not sure what wattage this microwave is - it's 'plumbed' into the wall, but I cooked it for 2 mins on high, could probably even do it with a bit less. Cheers! Oh and I'm going to add some coffee to the next one...

Chocolate emergency led me to this recipe! Thanks for all the suggested tweaks. I used all the quantities stated in the recipe but put in 3 squares of milk chocolate. I mixed the ingredients in a separate jug, greased the mug (large coffee-type mug, more like a bowl than mug) and binged for 2 minutes in a 900w microwave. Turned out ok! Slightly rubbery and more like a pudding/brownie than sponge but still goey nice enough for the job. The husband liked it! It served two of us, as it was quite rich. Would try again with different tweaks, maybe less cooking time and some nuts.

I just tried this recipe using the self-raising flour and putting it in the microwave for 2 minutes (1000 watt). The cake came out absolutely perfect and very sweet and tasty. I did use slightly less oil than recommended. Great recipe to do with the kids for a quick cake fix and so simple just throw all the ingredients into a very large coffee cup (think grande cuppuchino) and stir until all mixed together.

I tried this cake as my oven has died and I only have a hob and microwave.

I didn't have any cocoa so I used cadburys drinking chocolate instead, which worked fine. The only problem was that as I didn't reduce the amount of sugar it was very sweet.

I also used plain flower and had no problems with the cake rising or the consistency.

The only thing I didn't like was that the bottom of the cake sticks to the mug and was really hard to get out. I ended up with a lovely shaped chocolate cake (the top half that I cut off) and a pile of chunks of cake.

This recipe easily served 2 people as it is stodgy. I served the top nice looking half with a curl of vanilla ice-cream to my mum as an afternoon treat :).

I used self-raising flour as suggested, and switched the oil for 3 melted tablespoons of butter, cooked it for 2 mins and it came out perfect. A lovely indulgent sponge perfect to satisfy a craving quickly anytime!! Next time i'll have with custard nom nom :)

Lovely recipe for desperate cake lovers, BUT 3 mins is too long.

My micro is 900w, (not 1000 like specified here) and 3 mins dried it all out. I would say 2 - 2.5mins is enough to maintain its moisture.

Following a hybrid of the super helpful comments, and driven by the lack of useful things in my cupboards, I've actually managed to cobble together something rather tasty out of this for someone who had none (read, zero!) of the key flavour ingredients!

Ingredients
1 Monster bowl. No microwave gunk cleaning for me!
4 Tbsp flour, plain
1 Tsp. Baking powder
3 Tbsp. Muscovado sugar
1 Tbsp. Sugar
1 Tsp. cinnamon
1 egg
3 Tbsp. milk
3 Tbsp. oil

As above, I combined the wet ingredients separately before adding the dry, and found that 2.5 minutes was almost perfect in my 700 watt microwave- it did get a little chewier as it cooled, but seeing as I drenched it in treacle, I rather enjoyed the extra bite!

Def needs tweeks from the original:

I found this works well:
self raising instead of plain
5tbsp of sugar instead of 4
Melted butter instead of oil

I also just line the mug with some of the extra butter too. Like others have suggested I mix the dry (inc rasins, cherries and some nuts) and the wet, then combine the two. I layer a couple of spoons of mixture then add a couple of blocks of chocolate in the middle then add the rest of the mixture. I've found that an 800w microwave is fine at 1.50-2 mins, otherwise it tends to dry out. It does continue to cook afterwards remember so its best not to overdo it. Will maybe try with brown sugar when I next make them.

five stars for fun, and watching it rise is almost as fun as watching popcorn! howves.... little dry no way needs three mins more likes two... still pretty nice friday nine oclock fix to the munchies from store cuboard ingredients ... what a great evening in with the kids serve with a chilly glass of milk to fix all the above problems! DELISSSHHH!

I just made it with melted butter instead of the oil, demerara sugar, self raising flour and a handful of black cherries and cooked it in a huge mug for 2mins 30 and it was very nice - light, fluffy and chocolatey - may knock off a little time to get it more gooey next time

As above, but with added walnuts, raisins and ice cream.
2mins in 900w microwave and it came out really good.
(plain flour and sunflower oil used).

Worked out ok, next time I would use some milk chocolate in the middle to give it a chocolate flavour. Its not a dreadful recipe but adding a little baking powder made it rise nicely, which seemed to be many people's complaint.

I found that the cake was really rubbery so decided to experiment. i melted butter instead of the oil and added 3 tbsp of the melted butter and it worked really well. A little more fiddley and time consuming but i reckon its worth it in the end!!
