Preheat oven to 400 degrees. Line a 9" x 12" baking dish with foil or lightly coat with cooking spray.
Mix brown sugar and garlic in a small bowl.
Place chicken in the baking dish and spread the brown sugar/garlic mixture evenly over the chicken.
Bake chicken for about 10 minutes for tenders, 15-20 for chicken breasts, or until juices are clear.
Turn on the broiler and brush barbecue sauce evenly over chicken. Broil for about 5 minutes, careful not to let it burn.
I used chicken tenders because it’s what I had on hand, but sometimes I actually prefer that to the larger chicken breasts. There is a much quicker cooking time and no pounding required. I think my kids really like the more sauce, less chicken ratio!Store leftover chicken in an airtight container for up to 3-4 days. Reheat in the microwave for 45-60 seconds, or until warmed through.
