I tried using a large egg didn,t work when it came out the microwave was like a chocolate omelette (use large egg if thats your thing) also like other users said cooking time is wrong I tried 4m the first time and was over cooked (put it in for 4m if thats your thing) I recomend 2.5m.

This was the first microwave cake I tried (was a little unsure to begin with) but it turned out okay (ie it was edible) however it was extremely dense, this may have been to me not mixing it enough I'm not sure but it fitted in my mug okay and tasted alright so may try other microwave cakes soon to see if it makes a difference

Fitted fine into a big mug. I only used 3tbsp of sugar but then put frosting on the top so plenty sweet enough. Like everyone else said, the cooking time is wrong. I cooked mine for 4 minutes and far too long. I will try 2.5 next time. I'll also try replacing the cocoa for flour next time and make a vanilla cake. Perfect with ice cream.

First time as a midnight craving, didn't have caster sugar or self raising; so I substituted those for granulated sugar and plain flour. I used unsweetened cocoa powder but my cake turned out dry and from other comment this is normal? Next time I will definitely add more sugar, cake too bitter for my sweet teeth and unfortunately didn't eat it. Over flown in the microwave too, meh.

Wasn't until my husband had eaten the Microwave Mug Cake with custard for his dessert, did I realise I forgot to put the oil in. Not only was it very tasty it was also fat free !!!!

Don't leave it in the oven for as long as it says to. Also i found that you need to reduce everything by 1/3.

... and actually, while you are at it, you could simply adjust the recipe as posted to quantities to fit a mug... since everyone seems to have found it WAY too much (probably reduce by a third... oh, but then you have a problem with the single egg. Dang!). I started with three small (3 in/7.5 cm diam) ramekins instead of a mug and it made three modest-sized portions in those. It IS a little short on sweetness, but the sponge is good.

It would help if someone could edit the first line of the ingredients so the flour and sugar are not irritatingly concatenated like this.

This was quick and easy, but it only required about 2 minutes in a standard type microwave. I stopped it after about 2 .5 minutes when I saw it wasn't rising any more. Next time I will try about 2 mins but stop just after it stops rising.
