Using a sharp knife, cut through the two chicken wing joints; remove and discard wing tips. Place remaining wing pieces in a large resealable plastic bag. Add flour; seal and shake to coat. Transfer chicken to a 4- or 5-qt. slow cooker coated with cooking spray.
In medium bowl, combine remaining ingredients; pour over chicken. Cook, covered, on low until chicken juices run clear, 4-5 hours. If desired, top with chives and serve with ranch dip.
Test Kitchen tips
Uncooked chicken wing sections (wingettes) may be substituted for whole chicken wings.
When cutting or seeding hot peppers, use rubber or plastic gloves to protect your hands. Avoid touching your face.
