And they're my new favorite thing. 1 tube of refrigerated crescent roll dough marshmallows melted butter sugar and cinnamon, mixed Just roll out and separate the crescent wedges on a greased cookie sheet. Dip each 'mallow in melted butter, roll in the cinnamon and sugar, then roll up in a wedge of dough being sure to pinch it closed all around. Bake at 375 for 10-12 minutes and then enjoy the sweet, doughey goodness! And surprise... the marshmallow disappears as it bakes.
