Preheat the air fryer to 400 degrees F.

Add chicken drumettes to the basket of your air fryer and cook for 8 minutes.

Flip the chicken drumettes and cook for another 8 minutes.

At this point, the wings should be crispy and fully cooked. If they are not crispy or fully cooked (this can happen depending on the size of the drumettes) cook for another 2 minutes.

While the wings are cooking warm Dijon mustard, honey, unsalted butter, garlic powder, cayenne pepper, and kosher salt in a 12-inch skillet set over medium heat.

When the mixture is warm remove it from the heat.

Add the cooked wings to the honey mustard mixture and toss to combine.

Sprinkle with crushed red pepper flakes for additional heat.
