Preheat the oven to a temperature of 350°F (176°C).
Unfold the chilled pastry crust and press it into the 9-inch pie plate, ensuring that it is snugly fitted.
In a separate bowl, blend together butter, flour, dark brown sugar, and salt until you acquire a crumbly texture.
Disperse the cherry fruit filling equally over the bottom of the crust.
Top off with the crumb mix, giving it a nice hearty crunch.
Place in preheated oven for 45 minutes or until golden brown.
Allow it to cool before serving and garnish with Reddi-Wip Original Dairy Whipped Topping for an added smoothness.
