Ingredients:
- 3 1/3 cups all-purpose flour
- 1 teaspoon salt
- 1 cup butter-flavored shortening
- 12 tablespoons cold water
- 2/3 cup sugar
- 1/3 cup all-purpose flour
- 1 teaspoon ground cinnamon
- 3 1/2 pounds Granny Smith apples, peeled, cored, and cut into 1/4-inch-thick slices (about 10 cups)
- 1 cup quick-cooking rolled oats
- 1 cup packed brown sugar
- 1/2 cup all-purpose flour
- 1/2 cup butter
- 1 cup brown sugar
- 4 tablespoons butter
- 1/2 cup half-and-half
- 1 tablespoon vanilla
- Pinch of salt
Directions:
- Preheat the oven to 375 degrees Fahrenheit. Spray a 15x10x1-inch pan with nonstick cooking spray and set aside.
- To make the dough, combine 3 1/3 cups of flour and salt in a large bowl. Using a pastry blender, cut in the shortening until it looks like coarse crumbs.
- Add four tablespoons of cold water to the mixture and stir with a fork. Repeat with the remaining water one tablespoon at a time until the dough is moistened. Use your hands to form it into a ball.
- On a lightly floured surface, roll the dough into a 19×13-inch rectangle. Wrap it around the rolling pin and roll it into the prepared baking pan. Gently press the dough up the sides of the pan, trimming it to 1/2 inch beyond the edge. Fold the edge over and flute as desired. Chill the pan in the fridge.
- In an extra-large bowl, mix the sugar, 1/3 cup flour, cinnamon, and apples until the apples are evenly coated. Carefully spread the apple mixture over the chilled crust.
- For the crumb topping, combine the oats, brown sugar, and 1/2 cup flour in a bowl. Cut in 1/2 cup of butter until crumbly and sprinkle it over the apples.
- To make homemade caramel, melt 1 cup of brown sugar, 4 tablespoons of butter, half-and-half, vanilla, and a pinch of salt in a saucepan over low heat until smooth. Drizzle the caramel over the crumb topping.
- Bake for 35-40 minutes or until the apples are tender and the topping is golden brown. Let it cool before slicing.
