Move rack to upper quadrant of oven. Preheat oven to 300 degrees.
Process half of the oats: Place 1 ½ cups of the oats in a mini-chopper or food processor. Pulse for 10 seconds until pulverized to the size of quick oats. In a bowl, stir together with the remaining 1 ½ cup of whole oats and set aside.
In a Medium-sized, microwave safe bowl, heat shortening until melted, about 45 seconds. Whisk in salt, sugar, honey, molasses, water, and *optional cinnamon until light and creamy.
Add the oats to the creamy mixture and stir for two minutes until oats are completely coated.
Line the baking pan with a sheet of parchment on the bottom. Spread oats into an even layer, pressing firmly down using another piece of parchment so your hands won't stick. Press firmly to pack oats down.
Bake 25 to 30 minutes, or until edges start to golden. Do not disturb or stir the oats during baking or after. Let cool completely on the baking sheet untouched for 1 hour. Once cool, break or crumble granola.
