Preheat the oven to 325 degrees F. Line a 13x18 inch baking sheet with parchment paper.
In a large bowl, stir together the oats, coconut, almonds, pepitas, almond flour, flaxseed, chia seeds and hemp hearts.
Combine the maple syrup, sugar and water together in a saucepan. Bring to a simmer and whisk until the sugar has dissolved. Remove the pan from the heat and whisk in the vanilla extract, pumpkin spice and salt. Whisk in the oil and egg white until combined. Let cool for 5 to 10 minutes.
Once cool, pour the mixture into the dry ingredients. Stir to combine and make sure all of the oats, seeds and nuts are evenly mixed with the liquid.
Press the mixture into the pan, making sure it’s in one even layer. You can use another baking sheet to press down on the granola to make sure it’s packed tightly into the sheet.
Bake for 40 to 45 minutes, rotating the pan once during cook time, until the granola is deeply golden and brown.
