Grease an 8″ tin and line the base with greaseproof paper.
Combine all of the ingredients in a large bowl until well combined. Turn the mixture into the cake tin and level the top.
Bake in a pre heated oven at 140 centigrade for 1 hour, then cover with greaseproof paper and cook for a further 1 hour 15 minutes. The cake should be just firm to touch in the centre. Bake it in the middle of the oven. Good luck
