Mix together 3-4 tbsp creamy yogurt, 1 egg, and 1-2 tbsp flour of choice in a bowl
Add optional ingredients: protein powder, chia seeds, sweetener to taste, vanilla extract, and cinnamon if desired
Adjust flour amount based on desired texture: more flour for cake-like texture, less flour for creamy cheesecake-style
Pour mixture into an air fryer-safe container
Bake in air fryer at 250°C for approximately 20 minutes
Let rest for at least 30 minutes for cheesecake texture (optional, can be eaten immediately)
Top with warm berries, melted dark chocolate, nuts, almond butter, or other desired toppings
