Chocolate Milk Cake

I am expanding my patisserie skills by trying the choco milk cake.  This is a complex business requiring 700ml chocolate milk, 1Kg mixed fruit and two cups self raising flour.  I didn't use the full quota of 1Kg of fruit more like 800g.  Previous observations showed that a slightly less dense fruit cake was better.  After mixing in the fruit with the choco milk I  left it fermenting over night. Sift in the powder and place in the paper lined tin. I had this bun in the oven for 2hr 15min at 150° with no fan forcing.
