Preheat the oven to 400°. Line 2 rimmed baking sheets with foil. In a small bowl, whisk the brown sugar with the chile powder. Arrange the bacon strips on the foil and coat the tops with the chile sugar. Bake for 20 to 25 minutes, until caramelized and almost crisp. Transfer the bacon to a rack set over a sheet of foil to cool completely; serve.
