Preheat the oven to 350 degrees.
Combine the oats, nuts, cinnamon, salt, hemp hearts, and flaxseed in a large bowl.
Mix the syrup, oil, and vanilla in a separate bow.
Pour the syrup mixture over the oats and mix to combine thoroughly. You want to ensure the oat mixture is well coated with the wet ingredients.
On a parchment-lined baking sheet, spread the granola in an even layer
Bake the granola for 25-30 minutes, stirring halfway through. The granola should be golden on the edges. Don't overcook it; it can burn quickly.
Let the granola cool fully in the pan. Break into pieces and store them in an airtight container on the counter.
