Ingredients Apple Pie: 5 cups apples - peeled, cored and sliced ⅔ cup white sugar 2 tablespoons all-purpose flour
Streusel Topping: ¾ cup all-purpose flour ¾ cup rolled oats ½ cup packed brown sugar 1 teaspoon lemon zest ½ teaspoon ground cinnamon ½ cup butter
Create the streusel topping: Blend flour, oats, brown sugar, lemon zest, and cinnamon in a medium bowl. Butter-cut mixture is crumbly. Remove pie from oven and cover with streusel.
Lower heat to 375°F (190°C). Return pie to oven and bake 30–35 minutes more until streusel is golden and apples are soft. Avoid browning by loosely covering with aluminum foil.
