Add the softened cream cheese to a mixing bowl. Beat the cream cheese until it is smooth and fluffy.
Add the pumpkin puree, Greek yogurt, sweetener, vanilla extract, pumpkin pie spice, and cinnamon. Mix until combined and creamy. Taste and adjust sweetness if needed.
Chill in the refrigerator for at least 1 hour before serving (this helps it set and makes the flavors pop).
Divide into 4 bowls or ramekins, top with whipped cream (optional), and enjoy!
