Preheat a skillet or griddle over medium heat.

Butter one side of each slice of Hawaiian sweet bread.

Place half of the Brie cheese on the non-buttered side of one slice of bread.

Break the Hershey’s chocolate bar into pieces and arrange them on top of the Brie cheese.

Spread marshmallow cream generously over the chocolate layer.

Break the graham crackers into small pieces and sprinkle them over the marshmallow cream.

Place the remaining Brie cheese on top of the graham crackers.

Place the other slice of bread, buttered side facing out, on top of the Brie cheese to form a sandwich.

Carefully transfer the sandwich to the preheated skillet or griddle.

Cook the sandwich for about 4 minutes on each side, or until golden brown and the cheese is melted, using a spatula to flip it halfway through.

Once cooked, remove the sandwich from the skillet or griddle and let it cool slightly before serving.

Cut the sandwich diagonally and serve warm for a delightful indoor s'mores experience!
