Preheat the oven to 375 degrees. Combine the cinnamon and sugar together and mix well. Place the unrolled crescent rolls onto an ungreased cookie sheet. Spread a layer of butter on each triangle; top with cinnamon and sugar mixture. Roll from the bottom of the triangle to the point.
Place in the oven and bake for 8-10 minutes or until golden brown. Remove from the oven and serve while hot. Enjoy.
