Step 1

Grease 2 (8 1/2 by 4 1/2 by 2 1/2-inch) loaf pans with butter or vegetable cooking spray.

Step 2

In a bowl, combine the sugar and cinnamon. Set aside.

Step 3

Slice the thawed dough in half, lengthwise. Make 4 slits across each loaf, careful not to slice all the way through.

Step 4

Brush the loaves generously with melted butter, coating even the nooks and crannies. Roll it in cinnamon sugar, packing the mixture into the crevices with your hands.

Step 5

Place the loaves in the greased pans. Let them rest for 30 minutes, or until the dough doubles in size. Top the loaves with the remaining cinnamon-sugar mixture, if any.

Step 6

Meanwhile, preheat the oven to 300 degrees Fahrenheit.

Step 7

Top the loaves with the remaining cinnamon-sugar mixture, if any. Bake the bread for 18 minutes. Turn the pans around and bake for 17 more minutes, or until the tops are golden.

Step 8

When tapped, the pans should produce a hollow sound. Or, check with an instant-read thermometer. The internal temperature should be 195 to 200 degrees Fahrenheit.

Step 9

While baking, prepare the glaze. Stir together the sifted powdered sugar and liquid until smooth and lump-free.

Step 10

Let the loaves cool in the pan for 15 minutes. Drizzle the glaze while the loaves are still warm. Enjoy!
