Crust Ingredients
- 3 ¾ cups all-purpose flour
- ¾ teaspoon salt
- 1 ½ cups shortening
- 1 egg yolk, plus enough milk to make 1 cup of liquid
Filling Ingredients
- 2–3 handfuls Corn Flakes
- 10 Granny Smith apples, sliced and cored
- 4–8 tablespoons butter, cubed
- 1 cup sugar
- 1 teaspoon cinnamon
- 1 egg white
- 1 teaspoon sugar (for brushing)
Thin Frosting Ingredients
- ⅔ cup powdered sugar
- 2–3 dashes vanilla extract
- Milk, enough to make a thin frosting
- Prepare the Crust: In a mixing bowl, combine the 3 ¾ cups of all-purpose flour, ¾ teaspoon salt, and 1 ½ cups shortening. Add the egg yolk and milk mixture (enough milk added to the egg yolk to total 1 cup liquid). Mix until the dough forms.
- Roll Out Dough: Divide the dough in half. Roll out half the dough to fit a 15×10-inch cookie sheet pan, ensuring it covers the entire pan surface evenly.
- Add Corn Flakes: Evenly sprinkle 2-3 handfuls of Corn Flakes over the rolled-out dough to add a crisp texture beneath the apples.
- Arrange Apples: Place the sliced and cored Granny Smith apples on top of the Corn Flakes layer.
- Add Sugar and Cinnamon: Mix 1 cup sugar with 1 teaspoon cinnamon and sprinkle evenly over the apples. Dot the top with 4-8 tablespoons of cubed butter for richness.
- Cover with Top Crust: Roll out the remaining half of the dough and place it over the apples to cover the filling completely.
- Prepare Egg Wash: Beat the egg white and 1 teaspoon sugar together. Brush this mixture over the top crust to give it a beautiful golden finish. Cut several slits in the top crust to allow steam to escape during baking.
- Bake the Pie: Preheat the oven to 425°F (220°C). Bake the pie on the cookie sheet for 25-30 minutes until the crust is golden brown and the filling is bubbling.
- Make and Add Frosting: While the pie is hot, mix ⅔ cup powdered sugar, 2-3 dashes of vanilla extract, and enough milk to create a thin frosting consistency. Drizzle this frosting evenly over the warm pie for a sweet finishing touch.
Notes
- You can use 8-10 apples depending on their size; 8 were used in the test kitchen.
- A 15×10-inch cookie sheet pan is ideal for this recipe.
- Cutting slits in the top crust helps release steam and prevents sogginess.
- The Corn Flakes add a unique crunch and help absorb excess juice from the apples.
- Use Granny Smith apples for their tartness and ability to hold shape during baking.
