In a separate mixing bowl, beat the pumpkin purée, cream cheese, pumpkin pie spice, vanilla extract, half & half, and remaining maple syrup until thoroughly blended.
Transfer to individual dessert bowls. Cover and place in the refrigerator to chill for at least 1 hour.
To serve, remove from refrigerator and top with maple whipped cream, pecans, and a sprinkle of ground cinnamon or nutmeg if desired.
