The Ultimate Chocolate Cake

Autumn is really here with its gusts of wind and chilly mornings so for us it's time to get back into the kitchen and prepare our favourite "comfort food" recipes for cold breezy days!
This is a recipe from Trish Deseine's fabulous book "Chocolate" which features fantastic mouth-watering photos of chocolate in all its forms.

5 minutes prep
22 minutes cooking time
If possible cook it the day before you serve it ( or at least a few hours before)

2 big bowls
1 square cake tin
200 g dark chocolate ( I have also used Terry's dark chocolate orange)

Heat the oven to 190 C
Over a bain marie melt the chocolate and the butter in a bowl
Add the sugar and set aside for a minute or two
Add the eggs one at a time and stir in well with a wooden spoon
Finally add the sponful of flour and mix well
