This moist and rustic cake is simply delicious!
Preheat oven to 160C and grease and line a 20cm springform cake tin.
Beat the butter and sugar together until pale in colour. Lightly whisk the eggs and set aside.
Meanwhile, sift the dry ingredients together and in a separate bowl, combine the apples, jam and lemon juice, stir to combine.
Add the beaten eggs to the wet mixture, a little at a time, mixing well between each addition.
Gently fold in the dry ingredients and then fold in the apple and jam.
Spoon mixture into the cake tin, sprinkle with the demerara sugar and bake for one hour or until a skewer comes out clean.
