Below is the recipe and some photos. I only did half this recipe for 2 of us. I've given the ml forms that I used, as well as the original oz for those of you sensible enough to purchase scales before endeavouring to bake anything!
Chocolate Fudge Microwave Pudding
4 oz (120ml) flour (Self-raising if you can find it, or if not add 2tsp of baking powder)
4oz (120ml) sugar
1oz (2 tbsp) cocoa Powder
2oz butter (usefully my packet comes marked in 10g intervals :D)
1 egg, beaten
4 tbsp milk (or water worked OK too)
4oz (120 ml) sugar and 2oz (60ml) drinking chocolate
6oz (180ml) sugar and 1 1/2oz (3tbsp) cocoa powder
140ml hot water
Mix flour, sugar and cocoa powder together in a microwavable bowl (bigger than mine was!)
Melt butter in the microwave (medium heat) and stir into flour mixture, along with the egg and milk/water.
In a seperate bowl, mix together the sugar and cocoa powder/drinking chocolate for the sauce. Pour onto the cake mixture but don't mix. Pour the hot water on top.
Hopefully it'll look something like this (but in a bigger bowl because you are more sensible than me)
Put into the microwave at HIGH for 5-6 minutes or until set on top.
And hey, presto, a delicious chocolate pudding :D
Mine sunk slightly because I took it out too early due to aforementioned microwave destroying issues! It still tasted delicious!
