Preheat the oven to 375 degrees F and lightly grease a small baking dish.

In a bowl, stir together the drained chicken, cream cheese, buffalo sauce, and ranch until well combined.

Fold in half of the cheddar, then spread the mixture into the baking dish.

Sprinkle the remaining cheddar over the top.

Bake for 20 minutes until hot and bubbly around the edges.

Serve warm with celery sticks and tortilla chips.
