Preheat oven to 325° and line a sheet tray with parchment paper.
In a large bowl, combine the oats, pumpkin seeds, flax seeds, sugar, salt and cinnamon. Stir to combine.
Add in the coconut oil, maple syrup and honey/agave. Stir until mixture is well combined. Pour onto the sheet tray, spreading evenly. Bake for 30 minutes, stirring after 15 minutes.
Once it's done baking, let it cool without stirring it to create clusters. Once it's cool, break into clusters.
