Preheat oven to 350 degrees. Lightly grease a 9 x 13 inch baking dish or line with parchment paper.
In a large bowl, combine shredded chicken, softened cream cheese, and ranch seasoning mix. Stir until creamy and fully blended.
2 ½ cups cooked shredded chicken, 4 ounces cream cheese, 1 packet ranch seasoning mix
Fold in the crumbled bacon and 1 cup of the shredded cheddar cheese. The mixture should be thick and evenly combined.
¾ cup cooked crumbled bacon, 1 cup shredded sharp cheddar cheese
Using a serrated knife, slice the rolls in half horizontally, keeping them connected. Place the bottom half in the prepared baking dish.
12 Hawaiian sweet rolls
Spread the crack chicken mixture evenly over the bottom buns, pressing gently into an even layer.
Sprinkle the remaining ½ cup cheddar cheese evenly over the top.
0.5 cup shredded sharp cheddar cheese
Place the top half of the rolls over the filling.
In a small bowl, mix melted butter and garlic powder. Brush evenly over the tops of the rolls.
2 Tablespoons unsalted butter, ½ teaspoon garlic powder
Cover loosely with foil and bake for 15 minutes. Remove foil and bake an additional 5 minutes, until cheese is melted and the tops are lightly golden.
Let rest for 5 minutes before slicing along the roll lines. Garnish with green onions if desired.
1 Tablespoon chopped green onions
