Use room temperature cream cheese for a smoother filling without lumps. Chill your mixing bowl and beaters before whipping the cream to help it whip faster and hold better. Be gentle when folding in the whipped cream to keep the filling light and fluffy. For a crunchier crust, toast the graham cracker crumbs lightly before mixing with butter. For added depth of flavor, sprinkle a pinch of sea salt on top before serving to contrast the sweetness.
