Step 1

Preheat oven to 350°F. Stir together graham cracker crumbs, melted butter, granulated sugar, and salt in a large bowl until combined. Press mixture evenly into bottom of an 11- x 7-inch baking dish. Bake in preheated oven until crust is toasty and edges are golden, 12 to 14 minutes. Transfer baking dish to a wire rack; let crust cool completely, about 45 minutes.

Step 2

Beat heavy whipping cream in a medium bowl with an electric mixer on medium-high speed until stiff peaks form, about 1 minute. Set whipped cream aside. Beat cream cheese and sour cream in a large bowl with an electric mixer on medium speed until smooth, about 1 minute. Add powdered sugar and vanilla; beat until light and fluffy, about 2 minutes.

Step 3

Fold half of whipped cream into cream cheese mixture using a rubber spatula until just combined; repeat with remaining whipped cream. Spoon cream cheese mixture into cooled crust; smooth top using a small offset spatula. Pour cherry pie filling over cream cheese layer, spreading to edges of cream cheese mixture. Cover and chill until filling is firm, about 2 hours. Cut into 10 bars, and serve immediately.
