Step 1: Prepare the Dough

1. If using frozen dough, let it thaw according to package instructions. If making homemade dough, allow it to rise until doubled in size.
2. Preheat oven to 350°F (175°C). Grease a 9×5-inch loaf pan.

Step 2: Coat with Cinnamon-Sugar

1. In a small bowl, mix granulated sugar and cinnamon.
2. Lightly flour a surface and roll the dough into a log shape.
3. Cut four to five deep slits across the top of the dough, being careful not to slice all the way through.
4. Brush the entire loaf generously with melted butter, ensuring the butter seeps into the slits.
5. Roll the loaf in the cinnamon-sugar mixture, coating it thoroughly.

Step 3: Bake the Bread

1. Place the coated dough into the greased loaf pan.
2. Bake for 25-30 minutes, or until golden brown and fully baked through.
3. Remove from the oven and let cool slightly before transferring to a wire rack.

Step 4: Make the Icing

1. In a bowl, whisk together powdered sugar, milk, and vanilla extract until smooth.
2. Adjust the consistency by adding more milk for a thinner glaze or more powdered sugar for a thicker one.
3. Drizzle the icing over the warm cinnamon bread.

Step 5: Serve and Enjoy

1. Slice and serve warm for the best taste experience.
2. Enjoy as is or with a side of apple butter for an authentic Dollywood-style treat.
