Place the chicken breast in a shallow bowl and pour the buttermilk over it, letting it marinate for at least 15 minutes to tenderize.
In a separate shallow dish, whisk together the 2 tablespoons of whole wheat flour, garlic powder, onion powder, paprika, 0.25 teaspoon sea salt, and 0.25 teaspoon black pepper.
Remove the chicken from the buttermilk, allowing excess liquid to drip off, then dredge it thoroughly in the seasoned flour mixture until evenly coated.
Heat the avocado oil in a cast-iron skillet over medium-high heat and cook the chicken for 5-6 minutes per side until the exterior is golden brown and the internal temperature reaches 165°F.
Remove the chicken from the pan and set aside on a plate; lower the skillet heat to medium and add the ghee to the same pan.
Whisk in the remaining teaspoon of flour for 1 minute to create a roux, then slowly pour in the almond milk, whisking constantly until the gravy is thick and smooth.
Season the gravy with the remaining salt and pepper, then pour it over the chicken before serving immediately.
