In a medium bowl, combine butter, sugars and cinnamon. Mix until you have a spreadable paste.
Roll out dough into a large rectangle, about 1/4-inch thick. Evenly spread cinnamon-sugar butter all over it.
Starting with the short end, roll dough into a tube. Cut in half lengthwise. Twist dough to form one long braid. Bring both ends together to create a circular shape.
Bake for 25 minutes, or until dough is puffy and firm to the touch. The insides will be doughy and soft, like a cinnamon roll!
For the glaze:
In a medium bowl, whisk sugar, milk and vanilla. Drizzle glaze over the cinnamon wreaths.
Enjoy!
Notes
You can also use crescent roll dough or seamless dough sheets, rolled out. One dough tube makes one small cinnamon wreath (2-4 servings). Cinnamon-sugar butter in recipe will make enough spread for four wreaths / four crescent dough tubes.
