In a medium bowl, combine the crushed Oreo crumbs with the melted butter until all crumbs are moistened.

Press the mixture into the bottom of a 9x13 inch dish, creating a firm, even layer. Chill in the refrigerator while preparing the filling.

In a large bowl, beat the softened cream cheese and powdered sugar together until smooth.

In a separate bowl, whip the heavy cream with the vanilla extract until stiff peaks form.

Gently fold the whipped cream into the cream cheese mixture until well combined.

Spread half of this creamy filling over the chilled Oreo crust in an even layer.

Spoon the cherry pie filling over the cream layer, spreading it out evenly.

Spread the remaining cream mixture over the cherry layer, smoothing out the top.

Refrigerate the dessert for at least 4 hours, or until set, to allow the layers to firm up.

Before serving, top with additional whipped cream, grated chocolate, and cherries for garnish.

Slice into squares and serve chilled.
