Cut cream cheese into cubes, then add to a mixing bowl or the bowl of a stand mixer. Beat until smooth. Add maple syrup, spices, pumpkin and Greek yogurt and continue beating until well blended and no lumps remain.
In a separate bowl with clean beaters, beat whipping cream until stiff peaks form. 1 ½ cups of whipping cream will yield up to 3 cups of whipped cream. Set aside 1 cup for garnishing finished desserts. Fold the remaining 2 cups into the pumpkin mixture.
Divide among 8 dessert dishes. Chill until set. Just before serving, add a dollop of whipped cream and a drizzle of caramel sauce, if desired.
