Ingredients
Scale
Crust
- 3 3/4 cup all-purpose flour
- 3/4 teaspoon salt
- 1 1/2 cup shortening
- 1 egg yolk plus enough milk to make 1 cup of liquid
Filling
- 2–3 handfuls Corn Flakes
- 10 Granny Smith apples, sliced and cored
- 4–8 tablespoons butter, cubed
- 1 cup sugar
- 1 teaspoon cinnamon
Topping
- 1 egg white
- 1 teaspoon sugar
Thin Frosting
- 2/3 cup powdered sugar
- 2–3 dashes vanilla extract
- Milk, enough to make a thin frosting
Instructions
- Prepare the crust: In a large mixing bowl, combine the all-purpose flour, salt, and shortening. Add the egg yolk and enough milk to total 1 cup of liquid. Mix until a dough forms.
- Roll out dough: Divide the dough in half and roll out one half to fit a cookie sheet or baking pan evenly.
- Add Corn Flakes: Sprinkle 2 to 3 handfuls of Corn Flakes over the rolled-out dough, creating a crunchy base layer.
- Arrange apples: Place the sliced and cored Granny Smith apples evenly on top of the Corn Flakes layer.
- Add sugar and cinnamon: Mix the sugar and cinnamon together, then sprinkle this evenly over the apple layer. Dot the apples with cubed butter for richness.
- Top the pie: Roll out the remaining dough half to cover the apples and Corn Flakes, sealing the edges.
- Apply egg wash: Beat the egg white with 1 teaspoon sugar and brush this mixture over the top crust. Cut a few small slits in the crust to allow steam to escape during baking.
- Bake: Place the pie in a preheated oven at 425°F (220°C) and bake for 25-30 minutes until the crust is golden and cooked through.
- Prepare thin frosting: While the pie is still hot, mix powdered sugar, vanilla extract, and enough milk to create a thin frosting. Drizzle this over the warm pie for a sweet finishing touch.
Notes
- Use Granny Smith apples for their tartness and firmness, which holds up well during baking.
- The Corn Flakes create a unique crunchy barrier that absorbs excess moisture, keeping the crust crisp.
- Adjust the amount of butter and sugar to your taste preferences or for a richer pie.
- Make slits in the top crust to prevent the pie from bubbling over or becoming soggy.
- The thin frosting adds a lovely sweet glaze but can be omitted if preferred.
