Add the warm milk to the bowl of an electric mixer and sprinkle with yeast. Let the yeast dissolve for a few minutes or until a light foam begins to form around the edges, then whisk to dissolve completely.

Whisk in the orange zest, juice, butter, eggs, salt, and sugar until well combined.

Slowly add the flour, a cup at a time, stirring with a wooden spoon or spatula after each addition. At 4 cups, check to see how sticky your dough is. The dough should feel tacky, but it shouldn't cling to your finger. If needed, add more flour until the dough is just barely tacky and springs back when touched.

Place the bowl on the electric mixer fitted with the dough hook. Knead on medium speed for 6-7 minutes, or until it is smooth and beginning to pull away from the edges of the bowl.

Transfer the dough to a greased bowl and cover loosely with greased plastic wrap. Set in a warm place to rise until doubled in size, or about 1-1.5 hours.

Grease a 9 x 13 inch pan with a neutral cooking spray.

Sprinkle a work surface generously with flour, then turn the risen dough out onto it. Sprinkle the top of the dough with additional flour. Gently roll the dough into a rectangle approximately 18 x 11 inches in size.

Spread the cinnamon sugar mixture evenly over the rectangle. Begin to roll the dough tightly over the filling, starting on the long end. If the ends are very thin or much smaller in size than the remaining dough, cut off a small amount of each end.

Score the dough with a knife so it's divided into 12 equal slices. Slide a piece of unflavored dental floss underneath the roll along each score mark, then pull the two ends of the floss together to cut the dough. Nestle each roll, cinnamon swirl up, into the prepared pan.

Cover the pan with a tea towel and let rest in a warm place until puffed, about 30-45 minutes. Preheat the oven to 375 degrees.

Remove the tea towel, and cover the pan with foil. Bake for 25 minutes, then remove from the foil and bake for an additional 5-8 minutes or until rolls are golden brown on the edges, but still light and puffy in the center.

Pour the glaze evenly over the rolls and serve warm. You might have a little extra glaze, depending on how much glaze you prefer. You can save it and let people add it to individual rolls or use it as a fruit dip.
