Preheat oven to 300 F
Mix melted butter, canola oil, vanilla, and brown sugar together in a bowl.
In a separate, bigger bowl mix the oats, salt, and cinnamon together.
Add the wet ingredients to the dry ingredients. Mix well. You want all the dry ingredients to be coated by the wet ingredients.
Spread in thin layers on 3-4 cookie trays.
Bake for 25-30 minutes, stirring halfway through. Be sure to watch the granola carefully as it can burn quickly!
Take out of the oven and let cool. Mix in any add-ins.
Store in airtight jars or containers.
