Preheat the oven to 350 degrees F (175 degrees C).

Separate Hawaiian rolls and cut a 1/2-inch slit in the side of each one. Use a finger or the end of a spoon to create a larger opening and a space large enough to fill each roll with about 1 tablespoon filling.

Roughly chop apple pie filling and add to a bowl. Stir in 1 packet apple cider mix. Spoon filling into the prepared rolls.

Melt 4 tablespoons butter and brush each roll on all sides with melted butter. Place rolls on a lined baking sheet.

Bake rolls in the preheated oven until lightly toasted and golden brown, 12 to 14 minutes.

Meanwhile, stir together remaining apple cider packet, sugar, and cinnamon in a shallow dish and melt remaining butter.

Brush tops of rolls evenly with melted butter and coat each roll in sugar mixture.
