Place the chicken breast in a shallow bowl and cover with buttermilk; let it soak for 15 minutes.
In a separate dish, whisk together the almond flour, arrowroot starch, smoked paprika, garlic powder, sea salt, and black pepper.
Remove the chicken from the buttermilk, dredging it thoroughly in the flour mixture until fully coated.
Lightly spray or brush the chicken with avocado oil and air-fry at 375°F for 12-15 minutes until golden and cooked through.
While the chicken cooks, whisk the egg, oat flour, almond milk, and baking powder in a small bowl until a smooth batter forms.
Pour the batter into a preheated waffle iron and cook until the waffle is steam-free and crisp.
Plate the waffle, top with the sliced fried chicken, and finish with a drizzle of maple syrup.
