OT: Microwave chocolate pudding recipe

Somebody gave me this recipe at work, so I can't claim this as my own. Thanks, H, this is a great recipe!

This is really easy to put together and makes a lovely chocolate sponge pudding with
chocolate sauce:

Serves 4

Ingredients for pudding:
100g self-raising flour
100g caster sugar
50g margarine
25g cocoa
Pinch salt
Drop of vanilla essence
1 egg, beaten
4 tablespoons milk

Ingredients for top:
100g soft brown sugar
25g cocoa
150ml water (added at last minute)

Mix sugar, flour, salt and cocoa in a large* microwaveable bowl. Melt margarine in the microwave or on the stove, and stir into the mixture. Add the beaten egg and milk to the mixture. Beat well until everything's mixed in.

Pour into souffle dish (or leave it where it is and save washing up!)

For the top, mix all the ingredients except the water and sprinkle over the top of the mixture. Just before cooking, add the water over the top.

Cook in microwave on high for 5 mins (750W)

*It rises during cooking. You have been warned!

I usually halve this recipe (except for the egg) because it makes too much for two people and once it's cooked, it's so nice, I have to eat all of it! But you can refrigerate leftovers and reheat it of course.

I'm also guessing you could mix it up a bit (as I have done with white choc powder) and perhaps try it with coffee instead?
