In a large pan or pot add the butter and melt. Add the chopped apples, brown sugar and water, gently mix to combine. Cook on medium heat, stirring often until the apples are tender, when the sauce starts to thicken gently stir in the cinnamon and continue to cook until the sauce has thickened, approximately 15 minutes to cook and thicken the sauce.
Roll out the dough and fit into the pan, prick the bottom well with a fork, pour in the apple mixture and gently cover with the extra dough that hangs over the pan.
Brush the dough with a little milk and bake until the crust is golden, approximately 25-30 minutes. Let cool or serve warm. Serve with a scoop of ice cream or dust with powdered sugar before serving. Enjoy!
