Preheat oven to 350
Grease a cast iron skillet with 1 tablespoon butter
Remove dough from tube and cut it into 12 equal slices and roll each of them into balls. If you have a larger skillet (12"), you will need two tubes of dough so you will need to repeat this process for the second tube as well.
Put the dough balls around the edge of the skillet.
Mix melted butter and dry ranch dip mix in a small mixing bowl and brush over the dough balls.
Combine the chicken, cream cheese, ½ cup shredded cheese, buffalo wing sauce and ranch dressing in a large mixing bowl. Mix until well blended.
Pour the buffalo chicken mixture into the center of the skillet and spread it out until it is even and touching the dough slices.
Bake for 20 minutes until the dough is golden brown.
Add remaining shredded cheese on top of the dip and bake for another 5 minutes on the top rack of the oven.
Remove the skillet from oven and add the Jack O' Lantern features to the dip. Use the blue corn tortilla chips for the eyes and nose and the olives for the mouth.
