Prepare the crust: If using a pre-made pie crust, set it aside. If making your own, crush cookies or crackers and mix with melted butter. Press into the pie dish and chill.
Mix the cream cheese: Beat the cream cheese in a large mixing bowl until smooth and creamy.
Add the yogurt and sweetener: Mix in the yogurt, sweetener, and vanilla extract until well combined and smooth.
Incorporate the thickener: Gradually mix in the cornstarch or almond flour until fully incorporated.
Pour the filling into the crust: Carefully pour the filling into the prepared crust and smooth the top.
Chill: Cover with plastic wrap and refrigerate for at least 4 hours, preferably overnight.
Serve and enjoy: Slice and serve with your favorite toppings.
