Preheat oven: Set to 375°F. Line a baking sheet with parchment paper.
Make crumb topping: In a small bowl, mix flour, brown sugar, melted butter, sliced almonds, and cinnamon until crumbly. Set aside.
Roll out the pie crust on a lightly floured surface.
Spread a layer of almond cream in the center, leaving a 1-inch border around the edges.
Arrange the apple slices in your favorite pattern over the almond cream.
Fold and finish: Fold the crust edges over the apples, overlapping slightly. Brush edges with egg wash and sprinkle with sugar.
Top and bake: Sprinkle the crumb topping evenly over the apples. Bake for 20–25 minutes, or until golden brown.
Cool and serve: Let cool for 20 minutes before slicing. Enjoy warm or at room temperature.
