Preheat your air fryer to 375°F and lightly grease the basket with avocado oil spray.
Place the chicken breast in a bowl with buttermilk, ensuring it is fully coated to tenderize the meat.
In a shallow dish, combine the panko breadcrumbs, smoked paprika, garlic powder, sea salt, and black pepper.
Remove the chicken from the buttermilk, dredge it thoroughly in the seasoned panko mixture, and place it in the air fryer.
Air fry the chicken for 12 to 15 minutes, flipping halfway through until the exterior is golden and the internal temperature reaches 165°F.
While the chicken cooks, whisk together the oat flour, almond milk, egg white, baking powder, and avocado oil in a medium bowl until smooth.
Pour the batter into a preheated waffle iron and cook until the waffle is golden brown and easily releases from the iron.
Place the warm waffle on a plate, top with the crispy chicken breast, and finish with a drizzle of pure maple syrup.
