In a large mixing bowl, make the buffalo chicken filling. Add shredded chicken, buffalo sauce, softened cream cheese, ranch dressing, cheese, green onions and blue cheese (optional). Stir until very well combined.
Lay each tortilla flat and spoon about ¾ cup of buffalo mixture onto tortilla. Spread cream cheese mixture on tortilla in a thin, even layer, leaving about a ½ inch of bare tortilla at the edges.
Roll each tortilla up tightly. Wrap the rolled tortillas in plastic wrap and place in refrigerator for at least two hours.
Remove from fridge, unwrap, and lay on cutting board. Slice into 1'' pieces. I press the roll right by the cut to help maintain a round shape while cutting. It can help to use a serrated knife!
Serve with ranch or blue cheese dressing for dipping.
Notes
Make homemade buffalo sauce using 3 tablespoons hot sauce and 1 tablespoon melted butter. Add a dash of Worcestershire sauce. For hot sauce, I prefer Frank's Red Hot.
