Preheat the oven to 350 degrees F. Spray a 9x9 inch baking dish with cooking spray.
Add the chicken and the buffalo hot sauce to the baking dish, and toss to coat.
In a medium saucepan, combine the cream cheese and the ranch dressing over low heat until the cream cheese is completely melted and smooth. Sprinkle 1 cup of the shredded Mozzarella and Cheddar cheese over the buffalo chicken. Pour the cream cheese/ranch mixture over the chicken and toss to coat. Mix until well combined. Top with the remaining shredded cheese.
Bake for 20 - 30minutes. Serve hot with crackers.

Notes
Soften your cream cheese — Cold cream cheese won’t melt smoothly, I like to take mine out of the fridge 30 minutes to an hour before I plan to make this 5 ingredient buffalo chicken dip.
Don’t overbake — You want melty, not oily. Check it at 20 minutes; when it’s bubbling around the edges, it’s ready.
Mix cheeses — A blend of mozzarella (for melt) and cheddar (for flavor) makes a world of difference.
Make Ahead Tip - You can assemble the buffalo chicken dip up to a day in advance - just cover and refrigerate it unbaked. When ready to serve, let it sit at room temperature for about 20 minutes, then bake as directed until hot and bubbly.
