Cut chicken breast into bite sized pieces.
Add chicken, corn, sour cream, mayonnaise, salt, garlic powder, and chili powder to the slow cooker and mix to combine.
Cover and cook on high for 2-2.5 hours or low for 2.5-3 hours, or until the chicken is cooked through.
Place the cream cheese on top of the chicken mixture and cover for 5-10 minutes. Once the cheese is soft all the way through, stir in the cream cheese.
Top with crumbled cheese and chopped cilantro, and optionally, garnish with tajin. Serve warm and enjoy!
