The most likely reason for a greasy dip is that the cream cheese was not at room temperature when it was added to the mixture. Make sure to let the cream cheese soften before adding it to the rest of the ingredients. You can also try using reduced-fat cream cheese to cut down on some of the fat and calories. Another reason that the buffalo chicken dip might seem greasy is that too much hot sauce was used. Start with 1/2 cup of hot sauce and add more to taste. You can always add more, but you can't take it away once it's in there.
