Apple crumble with coconut

This apple crumble recipe is taken from recepten.se. The coconut in the crumble is a delicious addition to the more common recipe.

3 bramley cooking apples (large)
1½ tsp ground cinnamon
3 tbsp sugar 
2 tbsp potato flour (potato starch)


Crumble
150g butter (room temperature)
200g plain flour (3½ dl)
100g sugar (1 dl)
3 tsp vanilla sugar (if you prefer to use vanilla essence, just add a little more sugar to make up for the extra liquid)
1 cup dessicated coconut


Start with the crumble. Let butter reach room temperature in a bowl. Add flour, sugar, vanilla sugar, and coconut and mix with an electric mixer until the crumble is - well, crumbly!
Peel and cut the apple into pieces and place in a large pie form. Sprinkle the sugar, cinnamon and potato flour over the apple. Spread the crumble over the apple and bake in the oven at 200 degrees for about 25 minutes. Serve warm with cold vanilla whip.
