In a bowl, mix the flour, bicarbonate of soda, baking powder, salt and sugar together.
Rub in butter until it resembles fine breadcrumbs.
Mix in the milk and grated apple to form soft dough.
Turn onto a lightly floured surface and pat and shape into a flattish round about ½ inch thick. Place on a baking tray or stone round.
Brush with milk, then sprinkle over the sugar and cinnamon.
Bake for 20 mins until golden. Leave to cool and cut into wedges. Serve warm or cold with butter.
You could add some raisin or dates if you like dried fruit.
You could also cut out small rounds with a cutter to make individual scones, but reduce baking time to 15 minutes.
Try serving it as a dessert, hot with custard!
