Preheat oven to 350°F.
Wrap a bacon slice around each chicken tender. Secure top and bottom of bacon with two toothpicks per tender.
In a shallow bowl, mix together brown sugar and chipotle chili powder. Roll bacon-wrapped chicken in mixture, then place on rimmed baking sheet. Bake for 35 minutes, or until chicken is fully cooked and bacon is crisp. (Place under broiler, if bacon is not crispy.) Cool briefly on baking sheet, then roll in drippings and serve.
