Preheat the oven to 350°F (175°C).
In a mixing bowl, beat the softened cream cheese until smooth, then stir in the hot pepper sauce until evenly combined.
Fold the shredded cooked chicken and the ranch dressing into the cream cheese mixture until well incorporated.
Transfer the mixture to a baking dish and spread it into an even layer, then sprinkle the shredded cheddar cheese evenly over the top.
Bake for 30 minutes, or until the dip is hot and the cheese is melted and bubbly.
Serve the dip warm with your choice of dippers such as celery, carrot sticks, or tortilla chips.
