Preheat the oven to 160C/fan 140C/gas 3. Lightly grease a deep 20cm loose-bottomed cake tin.
Measure the flour, baking powder, sugar, eggs, almond extract and melted butter into a bowl. Mix well until blended, then beat for a minute.
Spread half this mixture in the prepared tin. Thickly slice the apples and lay on top of the mixture in the tin, piling mostly towards the centre. Using 2 dessertspoons, roughly spoon the remaining mixture over the apples. This is an awkward thing to do, but just make sure that the mixture covers the centre well as it will spread out in the oven. Sprinkle with the flaked almonds.
Bake in the preheated oven for 1¼-1½ hours until golden and coming away from the sides of the tin.
