Preheat oven to 200C/400F/Gas 6. Sift the flours with baking powder and cinnamon. Cut the fat into small pieces and rub into the flour mixture.
Stir in the apple, sugar and raisins, then add the egg and milk and mix to a stiff dough. Use two forks to pile 12 rough heaps of the mixture on to a greased baking sheet.
Bake for 12-15 minutes until the cakes are golden. Cool on a wire rack and sprinkle with a little caster sugar before serving.
