Well, I must admit I do not cook often, but today I've tried a quick recipe sent by a friend, and it ended up not too badly. This is all happening in a tea mug! Actually I used the biggest version of a cup I had in the house (that I normally use to have soup in), as the cake tends to raise and overflow, but you can use a normal mug, and then cut it into scone size pieces and put jam on it.
4 tablespoons of flour (levelled)
4 tablespoons of sugar (levelled)
1 tablespoon of cocoa (levelled)
half teaspoon of baking powder
Mix well the dried ingredients.
Add one egg and mix in well.
Add 3 tablespoons of milk and 3 tablespoons of oil.
Once well mixed, put cup in the microwave and cook for 4 mins at 850W.
I sprinkled mine with icing sugar, but you can decorate with icing, chocolate, jam, custard, cream, and whatever else takes your fancy, each to their own taste!
Hope you'll enjoy it as much as I have. The link is in Romanian, and more photos are attached, if you want to see it. Merci Giani!
