Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large mixing bowl, toss the chicken wings with olive oil, garlic powder, onion powder, smoked paprika, salt, and black pepper until evenly coated.
Arrange the seasoned chicken wings in a single layer on the prepared baking sheet.
Bake in the preheated oven for 40-45 minutes, turning halfway through, until the wings are crispy and cooked through.
While the wings are baking, prepare the homemade buffalo sauce. In a small saucepan over low heat, combine the hot sauce, grass-fed butter, apple cider vinegar, garlic powder, onion powder, smoked paprika, and salt.
Whisk the sauce until the butter is melted and all ingredients are well combined. Remove from heat and set aside.
Once the wings are done, transfer them to a large mixing bowl. Pour the homemade buffalo sauce over the wings and toss until they are fully coated.
Serve the Keto Buffalo Chicken Wings immediately, garnished with fresh herbs if desired. Enjoy with celery sticks and a side of ranch or blue cheese dressing for a complete meal.
