Preheat oven to 425°F. Toss together the Brussels sprouts, maple syrup, chile powders and salt. Wrap each Brussels sprout with a 1/2 slice of uncooked bacon. (Use wooden toothpicks to secure bacon in place if necessary).
Arrange bacon-wrapped Brussels sprouts on a wire rack positioned in a rimmed baking sheet, and bake for 30 minutes or until crisp.
Remove from oven and allow Brussels sprouts to cool slightly before transferring to a serving platter. Serve immediately.
