Combine all the dry ingredients in a large mixing bowl. In a small sauce pan, heat the wet ingredients together until the peanut butter and coconut oil have melted. Add the wet ingredients to the dry and stir until well mixed and all the ingredients are coated.
Separate the mixture onto two baking sheets, and bake for 30 - 35 minutes, until the granola is starting to brown. I recommend stirring and flipping it every 10 minutes to ensure even cooking.
Let cool completely then transfer to an air tight container. Store in a cool, dry place for two weeks.
