Preheat the oven to 350°F.
Cut the top off the Hawaiian round loaf. Carefully hollow out the center leaving about a 1-inch border around the sides and bottom. Cut the removed bread into bite-sized cubes and set aside for dipping.
Spread the softened cream cheese evenly across the bottom of the bread bowl.
Spoon the pizza sauce over the cream cheese. Top with shredded mozzarella and pepperoni.
Place the filled bread bowl on a sheet pan. Loosely tent the outside of the bowl with foil to keep the bread from getting too dark.
Bake for 20 to 25 minutes until the dip is hot and the cheese is melted and bubbly. Remove the foil for the final 5 minutes.
During the last 8 to 10 minutes of baking add the reserved bread cubes to the sheet pan to lightly toast alongside the bowl.
Serve warm with the toasted bread cubes and your favorite sturdy dippers.
