An experimental chocolate torte

In the search for the perfect home-made chocolate torte, I'm always trying out new recipes. This one worked out well:

200g chocolate (Green and Blacks slightly darker milk chocolate)
80g butter
100g brown sugar
4 eggs (medium sized)
25 g plain flour
1 tsp vanilla essence

Melt the chocolate and butter, mix in the sugar. Add the eggs one by one, then mix in the flour and vanilla essence.
Spoon into a cake tin and cook at gas mark 4 for about half an hour.
The top wasn't quite as crusty, and the inner quite as 'squidgy' as I would like - but it tasted good!
