How to Make It
Combine cream cheese, blue cheese, and white cheddar in the bowl of a food processor; process until smooth.
Heat a medium, nonstick skillet over medium heat. Add 1/4 cup of buffalo sauce and chicken. Cook, stirring frequently, until sauce chicken absorbs most of the sauce, about 2 minutes. Let cool to room temperature.
Stir chicken mixture, remaining ¼ cup Buffalo sauce, and celery into cream cheese mixture; mix until evenly incorporated. Scrape cream cheese mixture onto a parchment paper-lined baking sheet.
Using lightly moistened hands, shape cream cheese mixture into a ball. Wrap in plastic wrap and refrigerate for 45 minutes to 1 hour, or until it can be easily rolled.
Spread crushed crackers evenly on a rimmed baking sheet. Roll the cheese ball in crackers to evenly coat.
Place cheese ball on a serving platter; serve with celery and additional Ritz crackers.
