Preheat your oven to 325°F (160°C). Line a 6-inch springform pan with parchment paper.
In a large mixing bowl, beat together the cream cheese and Greek yogurt until smooth.
Add in the eggs, vanilla extract, cornstarch (or almond flour), and powdered sweetener. Mix until fully combined.
Pour the batter into the prepared pan and smooth the top.
Bake for 30–35 minutes or until the edges are set but the center still jiggles slightly.
Turn off the oven and leave the cheesecake inside with the door slightly open for 1 hour.
Chill in the fridge for at least 4 hours or overnight before serving.
