1) Peel, core and thinly slice the apples. Place in a bowl and cover with the lemon juice.
2) Mix together the butter, caster sugar, eggs, vanilla extract, flour and baking powder in a large mixing bowl. Preheat the oven to 180°C and grease and line a rectangular baking tin (~25 by 20 cm).
3) Spread half the cake mixture into the prepared tin. Arrange half the apples over the top and then repeat the layers. Sprinkle over the demerara sugar. Bake for 45-50 mins until golden and springy to the touch. Leave to cool for a few minutes then remove from the tin and cut into squares. Serve warm or cold.
