Step 1

Set an oven rack in the top position and preheat the broiler. Line a baking sheet with heavy-duty aluminum foil.

Step 2

In a large bowl, whisk together the olive oil, salt, garlic powder, chili powder, cumin, paprika, smoked paprika, and cayenne pepper (if using). Add the chicken thighs and toss to coat evenly. Arrange the chicken on the prepared baking sheet.

Step 3

Broil the chicken for 10 minutes, flipping once halfway through.

Step 4

While the chicken is in the oven, prepare the glaze: In a small bowl, use a fork to whisk the honey with 1 tablespoon of the vinegar.

Step 5

Remove the pan from the oven and brush half of the glaze on the chicken; broil for 1 to 2 minutes, until nicely browned. Remove the pan from the oven and turn the chicken thighs over; brush with the remaining honey glaze and broil for 1 to 2 minutes more, until the exterior of the chicken is caramelized. Remove the pan from the oven and sprinkle the chicken with the remaining 2 tablespoons vinegar. Transfer the chicken and pan juices to a platter and serve.
