Cinnamon Rolls

• 1 quart Whole Milk
• 1 cup Vegetable Oil
• 1 cup Sugar
• 2 packages Active Dry Yeast
• 8 cups (Plus 1 Cup Extra, Separated) All-purpose Flour
• 1 teaspoon  Baking Powder
• 1 teaspoon Baking Soda
• 1 Tablespoon  Salt
• 2 sticks Melted Butter
• 2 cups Sugar
• Generous Sprinkling Of Cinnamon
• _____
• MAPLE FROSTING:
• 1 bag Powdered Sugar
• 2 teaspoons Maple Flavoring
• 1/2 cup Milk
• 1/4 cup Melted Butter
• 1/4 cup Brewed Coffee
• 1/8 teaspoon Salt
  
  
  
  For the dough, heat the milk, vegetable oil, and sugar in a medium saucepan over medium heat to just below a boil. Set aside and cool to warm. Sprinkle the yeast on top and let it sit on the milk for 1 minute.
  Add 8 cups of the flour. Stir until just combined, then cover with a clean kitchen towel, and set aside in a relatively warm place for 1 hour. After 1 hour, remove the towel and add the baking powder, baking soda, salt, and the remaining 1 cup flour. Stir thoroughly to combine. Use the dough right away, or place in a mixing bowl and refrigerate for up to 3 days, punching down the dough if it rises to the top of the bowl. 
  Preheat the oven to 375°F.
  
  
  To make the filling, pour 3/4 cup to 1 cup of the melted butter over the surface of the dough. Use your fingers to spread the butter evenly. Generously sprinkle half of the ground cinnamon and 1 cup of the sugar over the butter. 
  
  Repeat the rolling/sugar/butter process with the other half of the dough and more pans. Preheat the oven to 375. Cover all the pans with a kitchen towel and set aside to rise on the countertop for at least 20 minutes before baking. Remove the towel and bake for 15 to 18 minutes, until golden brown. Don’t allow the rolls to become overly brown.
  
  While the rolls are baking, make the maple icing: In a large bowl, whisk together the powdered sugar, milk, butter, coffee, and salt. Splash in the maple flavoring. Whisk until very smooth. The icing should be somewhat thick but still very pourable.
