Apple Crumble / Apple Crisp

Apple crumble pie is my favourite pie. I can have it for breakfast, lunch and dinner. When you need a quick, delicious dessert, this pie will do the trick. 

Apple filling:
4 sliced apples (Granny Smith)
2 tsp lemon juice
1 tsp cinnamon powder

Crumble:
150 g butter
1 cup flour
1 cup oats
5 tbs caster sugar
A pinch of salt (if you use unsalted butter)
1 tsp vanillin sugar (optional)

Mix flour, oats, sugar and vanilla sugar in a bowl. Cut the butter in small pieces. Add them in the flour mixture and cut the butter into the dry ingredients with a fork or hand. I almost always use salted butter when I bake, because the salt brings out the flavours in sweet dishes. If you don't use salted butter, I would suggest you add a pinch of salt to the flour mixture. Also, please make sure that all the flour is well mixed with the butter. Otherwise you will end up eating raw flour. Put aside the mixture.

Heat oven to 350 degrees (175 C degrees). Fill a bowl with cold water and some drops of lemon juice. Adding lemon juice to the water will prevent the apples from turning brown. Peel and slice the apples and put them in the bowl with cold water. When finished slicing the apples, place them in a pie plate, spread cinnamon on them and lastly add the crumble. Put the pie in the oven and bake it for about 25 minutes in the lower-middle part of the oven. Meanwhile, you could start whipping the cream or custard to serve the pie with. You could also serve it with vanilla ice-cream. Good luck!
