Preheat your oven to 375°F (190°C).
Place the pie crust in a pie dish and bake according to package instructions. Let it cool completely.
In a mixing bowl, beat the softened cream cheese until smooth. Add sugar and vanilla extract, and mix until well combined.
Gently fold in the whipped cream until the mixture is smooth and creamy.
Spread a layer of the cream cheese mixture on the bottom of the cooled pie crust.
Arrange the sliced peaches on top of the cream cheese mixture.
Spread the remaining cream cheese mixture over the peaches, smoothing it out with a spatula.
Sprinkle cinnamon on top if desired.
Chill the pie in the refrigerator for at least 4 hours or overnight to set.
Before serving, garnish with whipped cream and additional peach slices.
Enjoy!
