Add 0.5g of vanilla bean or vanilla extract
Leave cream cheese, eggs, and Greek yogurt at room temperature for 20-30 minutes
Mix cream cheese and allulose powder together (important to make it smooth and creamy)
Beat the room temperature eggs, strain 2-3 times, and gradually add while mixing
Add Greek yogurt and mix thoroughly
Add lemon juice, vanilla bean or extract, salt, and mix well
Add almond flour and mix until well combined
Preheat air fryer to 190°C for 5 minutes
Bake at 180°C for 15 minutes first
Increase to 185°C and bake for 2 more minutes (cake will be a bit firmer); if you prefer a slightly jiggly center, bake at 180°C for 17-18 minutes
Let the cake sit in the air fryer with a little air circulation for 10 minutes, then cool at room temperature for 2-3 hours
Chill in the refrigerator for at least 4-6 hours, best after one day of aging
