Preheat oven to 375 degrees F. Spray a 9-inch pie pan with non-stick cooking spray and place the pie crust in the pan, fluting the edge.
In a medium bowl, whisk together the sugar and cornstarch. Whisk in the melted butter, corn syrup, and almond extract, then whisk in the eggs until fully combined and smooth.
Fold in the chopped apples and almonds until evenly coated in the filling.
Pour the filling into the pie crust-lined pan. If desired, top with pie crust cut into decorative shapes, or a second crust cut into strips and arranged in a lattice.
Bake for 50 minutes, or until the center of the pie is set and no longer jiggles when the pan is gently shaken. If the crust edges are browning too quickly, tent them loosely with foil for the remaining bake time.
Cool completely on a wire rack before slicing, so the custard-style filling has time to fully set.
