Spray the bottom of your crockpot with nonstick cooking spray for easy cleanup later on.
Place the two large chicken breasts directly on the bottom of the crockpot for even cooking throughout.
Add in black beans, corn, Rotel tomatoes, ranch seasoning, cumin, chili powder, onion powder, and water; mix well to incorporate all ingredients.
Place an entire block of cream cheese on top of the mixture without mixing it in; this helps create a rich creamy texture as it melts during cooking.
Cook on low for 6-8 hours or high for about 4 hours until chicken is tender and easily shredded.
Stir everything together after cooking; shred the chicken using two forks and serve topped with your favorite garnishes like cheese, sour cream, avocados, fresh tomatoes, or crunchy Fritos/tortilla chips.
