Slice the chicken breast into thick strips and submerge them in the buttermilk in a shallow bowl for at least 15 minutes.
In a small mixing bowl, whisk together the oat flour, egg, almond milk, and baking powder until a smooth waffle batter forms.
Preheat a mini waffle iron and pour in the batter, cooking until the waffle is golden-brown and firm.
In a separate shallow dish, whisk together the whole wheat flour, sea salt, black pepper, garlic powder, and smoked paprika.
Remove the chicken strips from the buttermilk, dredge them thoroughly in the flour mixture, and mist all sides with avocado oil.
Place the chicken in an air fryer basket and cook at 400°F for 10-12 minutes, flipping halfway through, until the coating is crispy and the meat is cooked through.
Plate the warm waffle, top with the crispy chicken strips, and finish with a light drizzle of pure maple syrup.
