Prepare cheesecake filling by combining cream cheese, 3 Tbsp. heavy whipping cream, and 3 Tbsp. granulated sugar in a small mixing bowl.
Beat on med-high speed until smooth and creamy, 2-3 minutes.
Layer parfait dishes with graham cracker crumbs, cheesecake filling, and apple pie filling. Alternate layers until you reach the top of the dish. (*Reserve 1 tsp. graham cracker crumbs)
Prepare whipped cream by combining remaining heavy whipping cream and remaining sugar in a chilled bowl.
Beat at medium-high speed until soft peaks form. Be careful not to over-beat!
Spoon whipped cream into a piping bag or ziplock bag with the corner cut; pipe onto the top of parfaits.
Sprinkle remaining graham cracker crumbs on top. Refrigerate until ready to serve.
