First, peel and chop apples
Take the apples in a baking dish and add; sugar, cinnamon, lemon juice, chopped walnuts. (If you like more sweet, you can add more sugar or if you like more sour, you can add more lemon juice. That’s optional.)
Then, mix everything and put in the oven for 25 minutes(390 °F),(200 °C)
Put flour, sugar and butter in a bowl. You can use blender or blend with your fingertips like me. Don’t knead, just mix everything until it is like sand.
Take the apples out of the oven, sprinkle the step 4 mixture evenly on top. And add the remaining chopped walnuts and throw in the oven for 25 minutes.(390 °F),(200 °C)
After 25 minutes, take the dessert out of the oven, let it rest for 15 minutes and serve with vanilla ice cream or cream. Then eat with joy and happiness.
