P-Dub's Cinnamon Rolls

You can see her version (with pics) here, although I typed it up for my family and thought I'd put it here too. They are amazing and while labor-intensive, really easy.

Ingredients:
4.5 c. milk, separated into 4 cups and 1/2 cup
1 c. vegetable oil
2 c. sugar
2 pkg. active dry yeast
9 c. flour
1 heaping tsp baking powder
1 scant tsp baking soda
1 heaping tablespoon salt
2 c. melted butter
lots of cinnamon
1 bag powdered sugar
2 tsp maple flavoring
1 tsp vanilla

Directions:
Mix 4 cups of whole milk, 1 cup of vegetable oil, and 1 cup of the sugar in a pan. "Scald" the mixture (heat until just before the boiling point.) Turn off heat and leave to cool 45 minutes to 1 hour.

When the mixture is lukewarm to warm, but NOT hot, sprinkle in 2 packages Active Dry Yeast. Let this sit for a minute so the yeast gets all warm and moist and happy.

Then add 8 (not nine) cups of all-purpose flour. Stir mixture together. Cover and let sit for at least an hour.

Now add 1 more cup of flour, baking powder, baking soda, and salt. Stir mixture together. At this point, you could cover the dough and put it in the fridge until you need it—overnight or even a day or two, if necessary.

Then roll the cinnamon rolls. Sprinkle surface generously with flour. Take half the dough and form a rough rectangle. Then roll the dough thin, maintaining a general rectangular shape. Rectangle should increase in both width and length as you roll it out.

Now drizzle 1 cup melted butter over the dough. Don’t be shy; lay it on thick!

Now sprinkle 1 cup of sugar over the butter, followed by a very generous sprinkling of cinnamon.
Now, starting at the opposite end, begin rolling the dough in a neat line toward you. Keep the roll relatively tight as you go. Some of the butter/sugar/cinnamon mixture may ooze out toward the end, but that’s no big deal. Pinch the seam to the roll to seal it.

Spread about 1 tablespoon of melted butter in each of seven round, foil cake or pie pans. Then begin cutting rolls approximately 3/4 to 1 inch thick and laying them in the buttered pans. Repeat this process with the other half of the dough.

Let the rolls sit for 20 to 30 minutes to rise, then bake at 400 degrees until light golden brown, about 15 to 18 minutes.

While the rolls are in the oven, make the maple frosting. To a mixing bowl, add the powdered sugar, maple flavoring, vanilla, 1/2 cup milk, and the rest of the melted butter (about 1/4 -1/2 cup). Stir it up. It should be thick but pourable. Taste and adjust as needed.

Generously drizzle frosting over warm rolls after you pull them out of the oven. Drown 'em.
