Place the chicken breasts in the bottom of a slow cooker.
In a bowl, mix hot sauce, chicken broth, garlic powder, onion powder, and pepper. Pour over the chicken.
Cover and cook on high for 3-4 hours or low for 6-7 hours, until chicken is tender.
Shred the chicken in the slow cooker using two forks.
If you'd like a thicker sauce, whisk together cornstarch and water in a small bowl, stir it into the chicken, and cook for another 20-30 minutes on high.
Serve on buns, in wraps, over salads, or with rice—your call!
