Note: this recipe works very well if you use chicken breasts with skin and bone; just bake for about 40 minutes.
Preheat oven to 400F; spray a baking sheet with nonstick spray like Pam; set aside.
In a shallow bowl or plate, like a pie plate, combine ranch dressing, garlic powder and cayenne pepper; mix well.
In another shallow bowl, place crushed potato chips.
Dip chicken chunks first into the ranch dressing mixture, then into the crushed potato chips; make sure you completely coat chunks; place coated chunks on prepared baking sheet.
Bake for 20 to 30 minutes (cut one in half after 20 minutes and check; depending on the size of your chunks, they'll likely be done), or until chicken is no longer pink inside; don't overbake or chicken will dry out.
Delicious when served with ranch dressing to dunk!
