Add undrained diced tomatoes and chicken broth. Bring to a boil, then add penne pasta, ensuring it is submerged. Cover and cook for 10-13 minutes until al dente.
Lower heat to a gentle simmer. Stir in buffalo sauce, cream cheese, cheddar, and mozzarella. Mix until combined and thickened. Add shredded chicken and red pepper flakes if desired.
For a smooth finish, stir in cold butter before serving.
Serve hot with optional toppings like extra cheese or fresh herbs.
