Heat the oven to 425°.
Line 2 baking sheets with foil and set cooking racks inside. Coat the racks with cooking spray.
Pour the honey into a measuring glass and then stir in the mustard until blended. Pour 4 tablespoons (1/4 cup) into a small bowl and set aside.
Pat the wings dry and add to a large bowl. Pour in the sauce (not the reserved 4 tablespoons) and toss to coat.
Line the wings up on the baking sheets, skin-side up and not too close. As you remove the wings from the bowl, try to wipe the skin side against the bottom/side of the bowl to smear on as much sauce as possible. Once all the wings are on the sheets, drizzle over any remaining sauce in the bowl. Sprinkle the wings with salt and pepper.
Bake for 20 minutes, swapping and rotating the pans halfway through.
Remove from the oven and lightly brush the wings with about 1-2 tablespoons of the reserved sauce. Flip the wings and lightly brush with about 1 tablespoon of sauce. Flip the wings again so they're skin-side up.
Bake for another 10-15 minutes, until the wings are golden and bronzed.
Remove from the oven and brush with any remaining sauce. Taste one and add more salt and pepper, if necessary.
