Preheat your oven to 375°F and spray a 9x13 casserole dish with cooking spray. Set aside.
In a large bowl, combine the cream cheese, half of the shredded cheddar, salt, black pepper, garlic powder, cumin and chili powder and stir until fully combined.
Add the chicken broth, stirring until well combined and set aside.
In the casserole dish, add an even layer of chicken, pasta, jalapenos, and bacon (reserving a few pieces for garnish).
Top the chicken and pasta with the cream cheese mixture and stir to make sure that all the pasta is covered with liquid.
Bake for 30 minutes or until the pasta has absorbed all the liquid.
Stir and top with the rest of the cheese.
Bake for another 10 minutes to melt the cheese.
Allow to cool for 10 minutes before garnishing with green onions, jalapeno slices and your reserved bacon. Serve warm.
