Make the Crumble: Mix graham cracker crumbs, melted butter, and sugar in a bowl until well combined. Set aside.
Prepare the Fluff: In a large mixing bowl, beat the cream cheese until smooth. Add powdered sugar and vanilla extract, continuing to beat until well blended. Fold in the whipped topping gently until the mixture is smooth.
Assemble the Layers: In your serving dish, layer half of the crumble mixture at the bottom. Spread the cream cheese mixture over the crumble layer evenly. Top with the cherry pie filling, spreading it out to cover the cream cheese layer completely. Finish by sprinkling the remaining crumble mixture over the cherry layer.
Chill: Refrigerate for at least 2 hours before serving to allow the flavors to meld and the dessert to firm up.
Notes
Ensure the cream cheese is at room temperature to avoid lumps in your fluff.
For a firmer set, let the dessert chill overnight.
