Preheat your air fryer to 375°F and line a small baking sheet with parchment paper for the biscuits.
Slice the chicken breast into even strips and place them in a shallow bowl with the buttermilk to coat.
In a separate shallow dish, whisk together the almond flour, smoked paprika, garlic powder, sea salt, and black pepper.
Remove each chicken strip from the buttermilk and dredge through the almond flour mixture until fully and evenly coated.
Place the chicken in the air fryer basket, lightly mist with avocado oil, and cook for 12-15 minutes until the exterior is golden and crispy.
While the chicken cooks, stir the oat flour, Greek yogurt, and baking powder in a small bowl until a thick dough forms.
Scoop the dough into two rounds on the prepared baking sheet and bake in the oven at 375°F for 10-12 minutes until the biscuits are fluffy and browned.
