Cook the rotini pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the diced chicken and season with garlic powder, onion powder, paprika, salt, and black pepper. Cook until the chicken is no longer pink, about 5-7 minutes.
Stir in the buffalo sauce and cook for an additional 2 minutes, allowing the chicken to absorb the flavors.
Reduce the heat to low and add the heavy cream to the skillet. Stir well to combine and let it simmer for 3-4 minutes until slightly thickened.
Add the cooked rotini to the skillet and toss to coat the pasta in the creamy buffalo sauce.
Stir in the shredded cheddar cheese until melted and well incorporated.
Remove from heat and sprinkle with crumbled blue cheese and sliced green onions before serving.
