crescent rolls
butter
cinnamon/sugar mixture
marshmallows

Preheat oven to 350°F. Melt butter in microwave or on stove-top. Open crescent rolls and separate into triangles. Dip a marshmallow and roll in the cinnamon/sugar. Place marshmallow at the wide end of the triangle and roll the dough around the marshmallow. Be sure to seal the dough around the marshmallow completely to avoid leaks. Place the dough in a muffin tin and repeat until all the crescent rolls are used.

Bake at 350°F for 10 to 12 minutes or until brown.
