In one bowl, beat cream cheese and powdered sugar until creamy. In another, combine sugar and ground cinnamon. Pour melted butter into the third bowl.
Cut off the crusts from the bread, roll each slice with a rolling pin. Spread the cream cheese on the bread, roll it up, dip in butter, then in cinnamon sugar.
Place the rolls on a baking sheet lined with parchment. Bake for 20 minutes in an oven preheated to 350 degrees.
