1. Roll out the dough into a large rectangle. Brush evenly with almond milk.
2. In a bowl, combine confectioners’ sugar with cinnamon and generously sprinkle evenly over the almond milk.
3. Roll the dough into a tight log, pinching the ends shut. Cut into 12 portions and place cut-side down into a greased nine- by 13-inch baking dish, cradling so none of the filling falls out. Leave some space in between them for the buns to rise.
4. Preheat the oven to 350 degrees Fahrenheit. Allow to rise 20 minutes then bake for 30 minutes, uncovered. Allow to cool completely before glazing.
