Preheat oven to 350 degrees. Grease a 8x8 inch baking pan.
In a large zip-top bag, mix together granulated sugar and cinnamon.
Cut cinnamon rolls into quarters and place the pieces in the bag with the cinnamon and sugar mixture. Toss to coat well. Arrange the cinnamon roll pieces in the prepared pan.
In a medium bowl, stir together the melted butter, brown sugar and maple syrup. Pour evenly over the cinnamon roll pieces.
Bake for 25-30 minutes, or until golden brown and bubbly. Remove from oven and drizzle with the frosting from the cinnamon roll packages. Serve warm.
