MAKE THE DOUGH

Cup of Yum
1. In a large bowl of a stand mixer, fitted with the dough attachment, mix together the flour and the yeast.
2. With the mixer on medium speed, add the warmed milk and melted butter (that's cooled slightly) to flour/yeast mixture. Next add in the sour cream, sugar, salt, and egg.
3. Beat at medium speed until the dough is smooth and elastic, approximately 5 minutes (Dough should pull away from sides of the bowl, but still stick to the bottom).
4. Spray a large bowl with nonstick cooking spray.
5. Place the dough in prepared bowl, turning to coat top.
6. Cover, and let rise in a warm draft-free place until the dough has about doubled in size, approximately 1 to 2 hours (seen note).

PREPARE THE SWEET ROLLS

1. Spray a 9-inch round pan (2 inches in height works well) with nonstick cooking spray. Set aside.
2. Lightly punch down the prepared dough and on a lightly floured surface, roll dough into a 14"x10" rectangle.
3. Spread the softened butter (6 tablespoons) evenly over dough.
4. In a small bowl, stir together sugar (⅔ cup) and zest (2 tablespoons) then sprinkle over butter.
5. Starting on one long side, roll dough into a log.
6. Slice into 9 to 10 rolls.
7. Place rolls in prepared pan.
8. Cover, and let rise in a warm draft-free place until almost doubled in sized, approximately 45 minutes to 1 hour.
9. Preheat oven to 350° F.
10. Bake, uncovered, until golden brown, approximately 30 minutes.
11. Let cool in pan on a wire rack for about 10 to 15 minutes.

MAKE THE ICING AND FINISH THE ROLLS

1. In a medium bowl, stir together the remaining 1 teaspoon zest, confectioners' sugar, and orange juice until smooth.
2. Drizzle and smear icing over warm rolls.
