Make the pie crust: In a large bowl, whisk the flour, sugar and salt together. Cut the cold butter into cubes. Use a pastry blender, a fork or your fingers to work the butter into the flour until the mixture resembles coarse sand.
Stir in the eggs and lemon juice. Use a wooden spoon or your hands to mix the dough together. Then, form it into a disc and wrap in plastic wrap. Refrigerate for at least 30 minutes.
Make the filling: Peel, core and slice the apples. Toss them with the sugar, cinnamon, cornstarch and lemon juice. Set aside.
Make the crumb topping: Melt the butter in a microwave safe bowl. Use a fork to stir in the flour, sugars and salt. Crumble the mixture with your fingers. Set aside.
Preheat oven to 375F degrees.
Assemble the pie: Roll the chilled dough out onto a floured surface until it is 10-11 inches in diameter. Coat a 9-inch pie plate with nonstick cooking spray. Transfer the dough into the pie plate, trimming the overhang if necessary.
Use a slotted spoon to transfer the apple filling into the crust. Sprinkle the streusel topping evenly over the apples. Cover with aluminum foil.
Bake 25 minutes. Remove the foil and bake an additional 20 minutes, until the top is golden brown. Cool completely in the pan before slicing.
