Peel, core and slice apples. Mix the apples with the sugar, flour and cinnamon in a bowl and place in a large greased baking dish.
Preheat the oven to 180 ° C.
In a second bowl you mix the oatmeal, brown sugar and flour. Add the softened butter and the chopped nuts and knead until everything is covered and pour over the apples.
Place in the oven for approx. 40 minutes until the crust is golden brown and the apples are tender.
Tip: We like to eat Apple Crisp fresh from the oven with a scoop of vanilla or cream ice cream and homemade caramel sauce.
