Place the cream cheese, chicken, hot sauce, ranch dressing, dry ranch mix, and 1 cup of cheddar cheese into the slow cooker.
Stir until combined.
Cover and cook on high for 1 ½ to 2 hours or low for 3-4 hours. Stir occasionally to prevent any cheese from burning.
30 minutes before serving cook and drain your pasta.
Add all the pasta to the slow cooker and stir to combine with the buffalo chicken.
Top with the remaining 1 cup of cheese and cover until the cheese melts.
Garnish with green onions and more ranch dressing if you like.
ENJOY!
