Preheat your oven to 400°F and line a small baking sheet with parchment paper for easy cleanup.
Slice the chicken breast into a flat, round patty shape roughly the same diameter as your biscuit.
Place the chicken in a small bowl and pour the buttermilk over it, allowing it to soak for at least 10 minutes.
In a shallow dish, whisk together the almond flour, garlic powder, onion powder, sea salt, black pepper, and paprika.
Remove the chicken from the buttermilk, letting the excess liquid drip off, then press it firmly into the seasoned flour mixture until fully coated.
Place the breaded chicken on the prepared baking sheet and lightly drizzle or spray with avocado oil to help it crisp.
Bake for 15 to 18 minutes, flipping the chicken halfway through, until the crust is golden and the internal temperature reaches 165°F.
During the final 5 minutes of baking, place the whole wheat biscuit in the oven to warm through.
Slice the warm biscuit in half, place the crispy chicken patty inside, and serve immediately.
