Preheat oven to 350°F.
Cut tortillas in half and set aside.
Mix chicken, sour cream, black beans, 1½ cups enchilada sauce, corn, half of the cilantro, and spices into a large bowl.
In a 9x13 pan, scoop ⅓ of the chicken mixture into the bottom of the pan. Spread evenly. Place one layer of cut tortillas over the chicken mixture. Top with ⅓ of shredded cheese.
Repeat with chicken mixture, tortillas, and cheese. In the end, there will be 3 layers of the chicken, tortilla, and cheese sequence. For the third layer, pour the remaining enchilada sauce over the tortilla layer and sprinkle the cheese on top.
Bake for 22-25 minutes or until the cheese is bubbly or the dish is cooked all the way through.
Serve with additional sour cream, chopped tomatoes, and cilantro if desired.
