Apple crumble makes a hot, tasty, comforting dish that is the perfect end to a family meal. Also there is no crust with an apple crumble, so it's easy to make and takes less time to prepare and cook than an apple pie.
Take the apples after washing them, core out the middle and throw away the pips. Cut the apples into wedges, about 1.25 cm (1/2 inch) thick or less. Place the apples in a bowl.
Juice the lemon over the apple pieces. This will keep the apples fresher longer and keep the apples from turning brown. In the bowl with the apples, add the sugar, cinnamon and the walnuts. Mix these all together and put to the side.
In another mixing bowl, mix the flour, sugar and cinnamon together and mix well with a spoon. Cut the pieces of butter in to small chunks and add to the flour mixture one at a time. After each piece of butter is added to the mixture, use your fingers to mix the flour mixture and butter together. This will make the crumble like texture for the crumble. After all the butter and flour mixture is blended, add the rolled oats to the mixture. Mix well with a spoon.
Take the pan and coat with cooking spray or butter, which ever you prefer. Add the apple mixture into the pan. Make sure the apple mixture is level as you can make it. Pour the crumble mixture on top of the apples and cover the entire mixture with the crumble. Even to the edges, if this is not covering well use your fingers to press the crumble mixture into the edges better. Cover the dish with tin foil and place in preheated oven for 30 minutes. Once the time is over, check the apple crumble and make sure that there is a bit of the apple mixture bubbling over slightly. This is a quick and easy way to tell the crumble is done.
This dish is served great with vanilla ice cream or whipped cream. This can be stored in the fridge for a week without any problems.
