Slice the chicken breast into even strips or bite-sized nuggets.
Place chicken in a small bowl and pour buttermilk over it, tossing to coat, and let soak for 10 minutes.
In a shallow dish, whisk together the almond flour, smoked paprika, garlic powder, onion powder, sea salt, and black pepper.
Remove each piece of chicken from the buttermilk, letting excess drip off, then dredge in the almond flour mixture, pressing firmly to ensure a thick coating.
Lightly grease the air fryer basket with avocado oil and arrange the chicken in a single layer without overcrowding.
Air fry at 400°F for 10-12 minutes, flipping halfway through, until the exterior is golden brown and the internal temperature reaches 165°F.
Transfer the crispy chicken to a plate and immediately drizzle with honey while the crust is still hot.
