This is not diet friendly, but delicious! I've adapted it slightly, so it's not that bad on the waist!!
8oz self raising flour
5oz flora light
2 large eggs
8oz caster sugar - you could maybe use sweetener and reduce the amount
1 1/2 tsp baking powder
1tsp almond essence
1 1/2lb green apples
8" loose bottomed tin
Preheat oven to 170c
Melt flora light in pan and pour into a bowl, add sugar, eggs, almond essence. Fold in the flour and baking powder. Spread just under 2/3 of the mixture into the tin. Peel and slice apples and arrange them on top of the mixture. Spread the remaining mixture on top and bake for 1 1/2 hours.
