First the sprinkles are made. Mix the cinnamon, sugar, flour, oatmeal and butter. Then grease an ovenproof baking dish with butter. Now peel the apples, cut them into small pieces and place them in the tin with the water and the remaining sugar. Finally sprinkle the crumble on top and bake in the preheated oven at 160-170 ° C for 30-40 minutes.
Tastes great with cream or vanilla sauce, but is also very tasty on its own.
