Preheat the oven to 350°F (175°C).
In a medium bowl, mix the shredded chicken, half of the diced avocado, garlic powder, and cumin.
In a blender, combine the remaining avocado, sour cream, and chicken broth to create a creamy sauce.
Warm the tortillas in a dry skillet to make them pliable.
Spread a small amount of the creamy avocado sauce on the bottom of a baking dish.
Fill each tortilla with the chicken mixture, roll them up, and place them seam side down in the baking dish.
Pour the remaining avocado sauce over the rolled enchiladas and sprinkle with cheese.
Bake in the preheated oven for 25–30 minutes until the cheese is bubbly and golden.
Garnish with fresh cilantro before serving.
