In a mixing bowl, combine graham cracker crumbs, melted butter, and granulated sugar. Mix until well combined, resembling wet sand. Press mixture into a 9-inch pie dish and chill for about 15 minutes to set.

In a large bowl, beat cream cheese and powdered sugar until smooth and creamy. Then add heavy cream and mix until soft peaks form.

Whisk together milk and chocolate pudding mix until thickened, then fold the mixture into the cream cheese mixture until fully combined.

Fold half of the sliced bananas into the chocolate filling. Spoon the filling into the chilled crust and top with remaining banana slices.

Cover with plastic wrap and refrigerate for at least 4 hours to set.

Spread whipped cream over the pie's surface and add chocolate shavings or curls and remaining banana slices.

Slice and serve immediately, enjoying the layers of chocolate, creamy filling, and sweet banana.
