6 Granny Smith apples, peeled and thinly sliced (¼-inch)
½ T ground cinnamon
¾ T granulated sugar
2¼ C all-purpose flour
2¼ C dark brown sugar
4/5 of a stick unsalted butter, melted
Toss apple slices in sugar and cinnamon. Mix flour and brown sugar on low speed with a mixer. Slowly add butter to flour and brown sugar and mix until you get a sand-like consistency. Butter and flour bottom and sides of 9-by-9 baking dish. Pour ¼-inch layer of flour/sugar/butter crumble into dish. Add a single layer of apples. Gently: Don’t press down. Continue layering: ¼-inch of crumble, then apples. Finish with a layer of crumble. Cover with foil. Bake at 350° for 90 minutes. Serve hot with vanilla ice cream. Thanks DC.
