Preheat the oven to 180°C/350°F.
Sift the flour, baking powder and the spices into a large bowl. Chop the apples into small slices and . Place in a bowl and toss with one tablespoon of the sieved flour mixture.
Add the eggs, butter, milk and sugar to the rest of the flour. Using a hand whisk, combine for about 1 minute, until its a creamy consistency. Next fold in the orange zest, lemon extract and sliced apple.
Spoon the mixture into a prepared cake tin that has been buttered and floured. Level off with the back of a spoon. Bake in the center of the oven for about 50 minutes, or until the cake feels springy in the center when lightly pressed. Cool in tin for tin minutes and then turn out onto a wire rack. Lightly dust with some icing sugar before serving, with a cup of hot steaming tea.
