Pat the chicken wings dry with paper towels for 5 minutes. This is CRUCIAL for crispy skin. In a large bowl, toss the wings with baking powder, salt, pepper, and garlic powder until evenly coated.

Arrange the seasoned wings in a single layer in your air fryer basket. Do not overcrowd; cook in batches if necessary for optimal crispiness.

Air fry at 375°F (190°C) for 20-25 minutes, flipping them halfway through. Increase the temperature to 400°F (200°C) for the last 5-10 minutes to achieve maximum crispness, ensuring an internal temperature of 165°F (74°C).

While the wings are cooking, melt the butter in a small saucepan over medium-low heat for 2 minutes. Add the minced garlic and cook for 30 seconds until fragrant.

Stir in the apple cider vinegar and buffalo sauce. Simmer for 1-2 minutes until slightly thickened. Remove from heat.

Once the wings are perfectly crispy, transfer them to a clean bowl. Pour the buffalo sauce over the wings and toss gently until every wing is coated.

Serve immediately and enjoy your perfectly crispy, flavorful keto wings!
