Put the apples in a medium saucepan with the water. Place the lid on and stew on a low heat for about 20 minutes, stirring occasionally until they have broken down and softened. Stir in the cranberry sauce and leave to cool.
Pre-heat the oven to 180°C / 160°C fan assisted oven / gas mark 5 and line and grease a rectangular baking tin 8” x 12”.
Add the rest of the ingredients into a large mixing bowl (or you can use a stand mixer) and rub together with your hands until everything has come together to form a dough.
Press ⅔ of the dough into the base of the baking tin to form an even layer.
Spread the cooled fruit on top.
Crumble the rest of the dough on the top and press down lightly into the fruit, don’t worry too much about it spreading out evenly.
Bake in the oven for 30 minutes until the top is golden brown and the fruit bubbling up.
Remove from the oven and leave to cool in the baking tray on a wire rack for 20 minutes.
Remove from the tin and cool completely on a wire rack before cutting into bars.
