Preheat the oven to 350° F (180° C).
Grease a deep cake tin and line with parchment paper.
Mix together the flour, the cinnamon and probably the baking powder, if necessary.
Cut in the butter until it has the consistency of breadcrumbs. Some people use their fingers in a rubbing motion to achieve this result, I prefer a pastry cutter.
Stir in the sugar. Add the egg and the milk. I would error on the side of 8 tablespoons of milk, maybe even more, as the cake can otherwise be a bit dry.
Stir in the apples and raisins.
Pour batter into the prepared cake tin. Sprinkle the raw sugar on top.
Bake 30-40 minutes until golden.
Allow to cool for 15 minutes and then turn out onto a wire rack.
