Baking One Hour Cinnamon Rolls is simple if you follow these steps closely:

1. Prepare the Dough: In a large bowl, combine 1 cup of flour, granulated sugar, instant yeast, and salt. Mix thoroughly.
2. Add Wet Ingredients: Gradually stir in warm milk and melted butter until the mixture is well combined.
3. Add More Flour: Add another cup of flour, mixing until the dough starts to form.
4. Knead the Dough: Turn the dough out onto a floured surface and knead for about 5 minutes or until smooth.
5. Let It Rise: Place the dough in a greased bowl, cover it with a damp cloth, and let it rest for 30 minutes in a warm spot.
6. Prepare Filling: While the dough is resting, mix brown sugar and cinnamon in a small bowl and set aside.
7. Roll Out the Dough: Once rested, roll the dough into a rectangle about 1/4 inch thick on a floured surface.
8. Spread Butter: Spread softened butter evenly over the dough.
9. Sprinkle Filling: Evenly distribute the brown sugar mixture over the buttered dough, pressing it slightly to adhere.
10. Roll It Up: Starting from one long side, tightly roll the dough into a log shape.
11. Cut into Rolls: Using a sharp knife, slice the rolled dough into 1-inch sections, creating about 12 rolls.
12. Place in Baking Dish: Arrange the rolls in a greased baking dish, ensuring they are close together.
13. Preheat Oven: Preheat your oven to 375°F (190°C).
14. Let Rise Again: Cover the rolls with a cloth and let them rise for 10-15 minutes.
15. Bake: Bake in the preheated oven for about 15-20 minutes until golden brown.
16. Make the Frosting: While the rolls are baking, whisk together powdered sugar, milk, and vanilla extract in a bowl until smooth.
17. Frost the Rolls: Once the cinnamon rolls are done baking, drizzle or spread the frosting over the warm rolls.
