01 -  Preheat oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish. 
 02 -  Place the King's Hawaiian rolls in the prepared dish. Using a small knife, cut a square into the top of each roll and gently pull out some of the bread, being careful not to cut through the bottom. 
 03 -  In a small bowl, mix together the melted butter, brown sugar, and cinnamon until well combined. Brush this mixture generously over the tops and insides of each roll. 
 04 -  In a separate bowl, use a hand mixer to beat the softened cream cheese until smooth. Add the granulated sugar and egg, mixing until creamy and well blended. 
 05 -  Carefully fill each roll cavity with the cream cheese mixture, distributing evenly among the rolls. 
 06 -  Bake in the preheated oven for about 15 minutes, or until the rolls are golden brown and the cream cheese filling is set. 
 07 -  Allow to cool slightly before serving. Best enjoyed warm.
