Preheat oven to 375 degrees. Stir apples, raspberries, granulated sugar, flour, lemon juice, and salt in a large bowl; set aside.
On a lightly floured surface, roll out 1 disk of dough to 1/8 inch thick. Cut into a 12-inch round. Fit into a 9-inch pie plate. Fill with apple mixture. Dot with butter.
On a lightly floured surface, roll out remaining disk of dough to 1/8 inch thick. Cut into a 12-inch round. Drape over filling. Trim overhang to 1 inch. Press edges to seal. Fold overhang under, and crimp as desired. Make five 3-inch slits in top crust. Refrigerate 20 minutes.
Whisk egg yolk and cream in a bowl; brush over top crust. Sprinkle with cinnamon and sugar. Bake until crust is golden and juices are bubbling, 1 hour 10 minutes to 1 hour 20 minutes. Place foil on rack below to catch juices. Tent pie with foil if browning too quickly. Transfer to a wire rack; let cool 4 hours (up to overnight).
