In a large mixing bowl, combine all-purpose flour, granulated sugar, yeast, and salt. Pour in warm milk, melted unsalted butter, and a beaten large egg. Knead the mixture until it's smooth and elastic, about 8-10 minutes.

Cover the bowl with a clean kitchen towel and place it in a warm area. Allow it to rise until doubled in size, which should take around 1 hour.

In a separate bowl, mix together sugar, cinnamon, and chopped peaches. Once the dough has risen, roll it out on a lightly floured surface. Spread melted butter, then sprinkle the peach filling evenly over the dough. Roll it up tightly.

Use a sharp knife to slice the rolled dough into 1-inch thick pieces. Arrange these rolls in a greased baking dish, leaving space for rising. Cover and let them rise for another 30 minutes.

Preheat your oven to 350°F (175°C). Bake the rolls for about 30 minutes, or until they are golden brown and your kitchen smells divine.

For the crumb topping, mix quick oats with melted butter and sprinkle this over the rolls. Bake for the last 5-10 minutes, or until the topping is lightly golden.

Let the rolls cool slightly before drizzling with a rich cream cheese glaze. Enjoy the bliss that follows!
