Preheat oven to 350F. Line a baking tray with parchment paper and set aside.
In a large bowl, add all of the dry ingredients. In a medium bowl, add all the wet ingredients and whisk together well to combine.
Pour the wet ingredients into the dry ingredients and mix well to combine. You'll know it's mixed enough when it looks like all the dry ingredients are coated in the pumpkin mixture.
Pour the mixture out onto the baking tray and spread it out evenly. The thinner the layer, the better it will bake.
Bake for 20-25 minutes, mixing every 10 minutes. You'll know it's done when the oats start to feel crunchy and look golden.
Remove from oven and let cool completely before storing in an airtight container.
