Preheat the oven
to 180'C/350'F/Gas4. Grease and line an 18cm/7in
round cake tin.
Toss the apple
with the lemon juice and set aside. Sift the flour
and baking powder together, then rub in the butter,
until the mixture resembles breadcrumbs.
Stir in
115g of the brown sugar, the apple and
the egg, and mix well, adding sufficient milk to
make a soft dropping consistency.
Transfer the
dough to the prepared tin. In a bowl, mix together
the remaining sugar and the cinnamon. Sprinkle over
the cake mixture, then bake for 45-50 minutes, until
golden. Leave to cool in the tin for 10 minutes,
then transfer to a wire rack.
