This is a really good dessert for a chilly night - either with custard or some cream. It's one of those puddings that has sponge on the top and a chocolatey sauce underneath.
In a large bowl, combine flour, cocoa, pinch of salt and caster sugar. In a jug blend milk, egg, melted butter and vanilla. Pour the wet ingredients into the dry and blend until smooth.
Put the mixture into a buttered baking dish (4 cup capacity) and put on a baking tray (in case of any overflows in the oven). Combine brown sugar and cocoa and sprinkle evenly over the top of the pudding mixture.
Carefully pour 1 cup of boiling water over the top of the pudding (pouring it over the back of the spoon will spread the water more evenly).
1 cup self raising flour
1/3 cup cocoa (divided into two - one half for pudding, other half for topping)
pinch of salt
1/2 cup caster sugar
1/2 cup milk
60 g unsalted butter, melted
1/2 tsp vanilla extract
1/2 cup lightly packed brown sugar
