Mix the graham cracker crumbs, brown sugar, and melted butter until every crumb is evenly coated.
Press the crumb mixture firmly into a 13-by-9-inch dish and freeze it for about 15 minutes while preparing the filling.
Beat the softened cream cheese, granulated sugar, and vanilla until smooth and free of lumps.
Add the thawed whipped topping and mix on low speed just until evenly incorporated.
Spread the cream-cheese filling evenly over the chilled crust, then cover it completely with both cans of cherry pie filling.
Cover and refrigerate for at least 4 hours before cutting into twelve portions and serving.
