Wash the chicken and pat dry. Add to a bowl.
Add ginger powder, garlic powder, paprika, black pepper, turmeric, and salt. Mix well to coat every piece.
Cover and marinate for at least 30 minutes. For best results, marinate 4 to 6 hours.
Preheat the air fryer to 200°C (400°F). Arrange chicken in the basket in a single layer.
Air fry at 180°C (360°F) for 20 minutes. At the 10-minute mark, flip each piece and brush with melted butter.
Check that the surface is charred and blistered. Confirm internal temperature reaches 74°C (165°F).
Arrange chicken on a plate. Mix 3 tablespoons fresh cream with 1 teaspoon chaat masala. Drizzle over the chicken.
