In a small bowl, whisk together the buttermilk, paprika, garlic powder, sea salt, and black pepper.
Submerge the chicken breast in the buttermilk mixture and marinate for 15 minutes.
Preheat the air fryer to 375 degrees and grease the basket with avocado oil.
In a shallow dish, combine the almond flour and arrowroot powder.
Remove the chicken from the marinade and dredge it in the flour mixture, pressing firmly to coat.
Air fry the chicken for 12 to 15 minutes, flipping halfway, until golden and cooked through.
Stir together the whole wheat flour, Greek yogurt, and baking powder until a dough forms.
Shape the dough into a small biscuit and bake at 375 degrees for 10 minutes until risen.
Serve the crispy chicken with the warm biscuit.
