Preheat oven to 350 degrees F.
FOR CRUST: Mix crushed graham crackers, melted butter and sugar together then press evenly into the bottom of an 11x7-inch baking dish. Bake for 5-8 minutes. Remove from oven and let cool completely before making filling.
FOR FILLING: Pour heavy cream into a large bowl. Using an electric hand-mixer beat cream until small peaks form and it thickens.
In another bowl, beat together the cream cheese and powdered sugar. Fold in the whipped cream. Pour it onto your graham cracker crust and gently spread out evenly over the crust. Spread cherry pie filling over the top. Cover and place in fridge to set at least 3 hours or overnight.
Cut into squares and serve!
