Prepare the crust: Mix graham cracker crumbs, melted butter, and sugar. Press mixture into the bottom of an 8-inch cake pan.
Make the filling: Beat softened cream cheese and sugar until smooth. Add eggs, sour cream, and vanilla extract, and beat until combined.
Assemble the cheesecake: Pour the cream cheese filling over the prepared crust, smoothing it out evenly.
Cook in the air fryer: Preheat air fryer to 320°F (160°C). Place the pan inside the air fryer and cook for 20-25 minutes, checking for a slight jiggle in the center.
Cool down: Remove cheesecake from the air fryer, let it cool at room temperature, and refrigerate for at least 2 hours before serving.
Serve: Top with your favorite fruit, whipped cream, or chocolate ganache and enjoy!
