Found it, it's WWB's recipe. It was really easy, texture a bit like a soft scone, was really moist and tasted lovely.
8oz self raising flour
pinch of salt
4oz butter or margarine
2oz raisins
2 eating apples, peeled, cored and roughly chopped
3 oz granulated sugar
1 egg, beaten
2 tablespoons milk
Sift the flour and salt, rub in the butter until it resembles breadcrumbs Stir in the raisins, apples and sugar Add the egg and milk, mix with a knife. The dough will be soft.
Spoon the mixture into a greased 8" sandwich tin, bake at 180C for about 50 minutes, or until a skewer inserted into the middle comes out clean. You may need to cover the cake with tin foil if it cooks too quickly on the outside. Cool in the tin. When you turn it out, sprinkle with extra sugar.
