Place the chicken breasts in the bottom of the crock pot.
Pour the Rotel tomatoes, corn, and black beans over the chicken.
Sprinkle the ranch dressing mix, chili powder, cumin, onion powder, garlic powder, salt, and pepper evenly on top.
Add the cream cheese block on top of everything.
Pour in the chicken broth.
Cover and cook on low for 6–8 hours or on high for 3–4 hours.
Before serving, shred the chicken with two forks and stir everything until the cream cheese is fully mixed in.
