Preheat the oven to 400ºF. Line a baking sheet with parchment paper or foil, then place two wire cooling racks over top to elevate the chicken wings.
In a small bowl, stir together the cornstarch, salt, pepper, and garlic powder. Pat the chicken wings dry, then add them to a bowl with the cornstarch mixture, and stir until the chicken wings are coated.
Place the cornstarch coated wings on the prepared baking sheet (on the wire racks). Bake in the oven for 50 minutes, give or take 5 minutes depending on the size of the wings, or until they are light golden brown and the skin is crispy.
While the wings are baking, make the honey mustard sauce. Stir together the mayonnaise, Dijon, yellow mustard, honey, vinegar, garlic powder, paprika, salt, and pepper in a bowl.
When the chicken wings are finished baking, place them in a clean bowl and pour the honey mustard sauce over top. Stir until the wings are coated. Serve immediately.
*This recipe makes enough honey mustard to coat the chicken wings. If you'd like enough honey mustard sauce to have extra for dipping, like in the photos, I suggest doubling the sauce ingredients.
