Divide the prepared, chilled pie crust into thirds – two-thirds for the bottom crust and one-third for the lattice topping.
Roll out the bottom crust on a well-floured work surface into a large circle, a few inches larger than your pie pan. I use a 9-inch pie pan.
Gently roll the dough onto your rolling pin to transfer it and unroll over the pie pan. Gently shape the dough into the pan, then pierce the bottom of the dough with a fork all over. This will prevent pockets from forming during the baking process.
Making the Pie Filling:
Preheat the oven to 350°F.
First, peel and core the apples. I like to cut mine in half, then use a paring knife to cut out the cores.
Using a sharp knife or mandoline slicer, slice the apples thinly, about 1/6-th-inch in thickness. Transfer the sliced apples into an extra-large mixing bowl.
Add the cranberries, sugar, flour, cornstarch, salt, cinnamon, vanilla extract, and cubed butter. Use a spatula to toss everything together. The apples should be well coated, and no dry flour remains in the bowl.
Transfer the apple pie filling into prepared pie crust, heaping the sliced apples into a mound. This recipe makes a lot of filling, but the apples will settle during the baking process.
Creating Lattice Pie Crust:
For the lattice pie topping, roll out the final portion of pie dough into a long rectangle. Use a sharp knife to cut the dough into long strips.
Arrange 6 to 7 strips of dough running one way on top of the pie filling. Arrange the longer strips near the center of the pie, spacing the strips about an inch apart.
Pull back half of the strips, lay a strip of dough perpendicular to the rest, then fold the strips back. Repeat this process, alternating the strips of dough to create a lattice effect.
Once finished, go around the edges and press the strips and the bottom crust together, forming a thick rim around the edges. Crimp the edges of the pie with a fork, a pie press, or crimp using your fingers.

Baking Instructions:
Brush the beaten egg gently over the top of the pie crust using a pastry brush. Sprinkle large, granulated sugar over the top, if desired.
Bake the apple pie in a preheated oven to 350°F for 1 hour and 15 minutes. After 25 minutes, place a pie crust proctor around the edges of the pie to prevent them from burning.
Once baked, remove the pie from the oven and let it cool on a wire rack for about 1 to 2 hours, allowing the filling to cool and thicken further.
Serving Suggestions:
I recommend serving this cranberry apple pie warm. Use a sharp, serrated knife to slice through the buttery crust, then gently lift and plate.
Serve this apple pie with a scoop of vanilla ice cream or whipped cream on the side.
