In a large bowl, combine 300 g of all-purpose flour, 60 g of granulated sugar, and 1 teaspoon of salt. Add 220 g of cold, cubed unsalted butter and mix until the mixture resembles coarse crumbs. Gradually incorporate 2½ tablespoon of cold water until a dough forms. Shape the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 30 minutes to firm up.

While the dough chills, melt 75 g of unsalted butter in a skillet over medium heat. Add your sliced apples, 5 tablespoon of brown sugar, 1¼ teaspoon of ground cinnamon, and ¼ teaspoon of salt. Cook the mixture for 10–12 minutes or until the apples are tender and slightly caramelized. Remove from heat and let the filling cool down to room temperature.

Preheat your oven to 190°C (375°F). Take half of the chilled pie dough and roll it out on a floured surface until it’s large enough to fit your pie dish. Carefully transfer the rolled dough to the dish, trimming any excess that hangs over. To enhance flavor and texture, sprinkle a thin layer of almond flour evenly on the bottom.

Pour the cooled apple filling into the prepared crust, spreading it out evenly. Roll out the remaining dough and either cut it into lattice strips for a decorative top or cover the filling entirely with a second dough layer. Ensure you crimp the edges well to seal your delicious Apple Pie à la Mode tightly, preventing any filling from leaking out.

Prepare an egg wash by whisking together one egg and 1 tablespoon of water until blended. Brush this mixture over the pie crust for a beautiful golden finish. For an extra touch of sweetness, sprinkle brown sugar over the top, which will caramelize during baking and add a delightful crunch.

Place the assembled pie into your preheated oven and bake for 50–60 minutes. Keep an eye on it, and look for a golden brown top and bubbling filling as visual cues that your pie is ready. Once baked, remove the pie from the oven and allow it to cool for at least 30 minutes—this will help the filling set.

After the pie has cooled slightly, slice it into generous pieces. Serve each slice warm, generously topped with a scoop of creamy vanilla ice cream.
