Preheat your air fryer to 375°F (190°C).
In a small bowl, soak the chicken breast in buttermilk for 10 minutes.
In a separate shallow dish, combine the almond flour, panko, sea salt, black pepper, garlic powder, and paprika.
Remove the chicken from the buttermilk, letting excess drip off, and dredge thoroughly in the flour and spice mixture.
Lightly mist the chicken with avocado oil and place in the air fryer basket; cook for 12-15 minutes, flipping halfway through, until golden and cooked to 165°F.
While the chicken cooks, whisk together the oat flour, egg white, almond milk, and baking powder in a medium bowl until a smooth batter forms.
Pour the batter into a preheated, lightly greased waffle iron and cook until the waffle is crisp and golden brown.
Place the hot waffle on a plate, top with the crispy air-fried chicken, and drizzle with the pure maple syrup.
