NOTE ADDED Jan 27, 2012: Please note that this is NOT a serious cake recipe! It is a fun recipe, for a quick choc snack. It may work for you, or you may have to make adjustments, or it might not work for you. Please do not judge this little recipe as if it is a chocolate cake -- as you will see from the reviews, they range from "great!" to "awful!" LOL! ORIGINAL INTRO: This recipe is doing the e-mail rounds! I do not know where it originated, but if you have kids, teenagers, or a sweet tooth yourself, it works!! A chocolate cake in a mug, for one person! Do use a LARGE mug! I never, ever post recipes like this which I have not made, and I'm not a microwave fan, but this one, for parents of the above-mentioned people, just has to be posted. Delicious with whipped cream, ice cream or custard, they say! It must be great to mix a choc cake in a mug, and have a hot "cake" within 3 minutes!!
