Not Your Mama's Cinnamon Rolls

Everyone's been asking for the recipe to these Cinnamon Rolls. It's a recipe that I got from my cousin, but it's been modified for my family. It does require a little planning ahead. I prep my rolls right before I go to bed the night before. And put them in the oven to rise during the night.
Prep Time: 5 Min
Cook Time: 19 Min

12 Rhodes dinner rolls in a greased 9x13 Pan
Melt 1 stick (1/2 Cup) butter in a bowl
Add 1/3 Cup brown Sugar to melted butter
Add 1 Tsp Cinnamon to melted butter
Stir and Spoon over Frozen rolls
Place 9x13 pan in the oven and let rise during the night.
By morning they should have filled the pan.
Turn the oven on to 350, and set the timer for 19 minutes. Leave the rolls in the oven the whole time.
When the timer goes off, remove the rolls from the oven. The tops should be golden brown.
Wait 10 minutes and Frost.
Frosting:
2 Cups powdered Sugar
2TBSP butter
1 TBSP Vanilla
Sprinkle of Cinnamon
A Couple TBSP Milk, to get desired texture and thickness.
Spoon on top of rolls and Enjoy!
