Preheat your oven to 425°F and line a baking sheet with parchment paper or a silicone mat.
In a shallow bowl, pour the buttermilk and season with a pinch of salt, pepper, garlic powder, and paprika.
Place the chicken breast between two sheets of plastic wrap and lightly pound it to an even thickness if desired.
Submerge the chicken in the buttermilk mixture, ensuring it is well-coated. Allow it to marinate for at least 30 minutes in the refrigerator for best flavor.
In a separate plate, spread out the almond flour mixed with the remaining garlic powder, paprika, salt, and pepper.
Remove the chicken from the buttermilk, allowing any excess to drip off, then dredge it in the almond flour mixture, pressing lightly to adhere the coating.
Place the coated chicken on the prepared baking sheet. Optionally, lightly spray the top with olive oil spray for extra crispiness.
Bake in the preheated oven for 20-25 minutes, or until the chicken reaches an internal temperature of 165°F and the coating turns golden and crispy.
Remove from the oven and let rest for a few minutes before serving.
