Preheat the oven to 325F. Line a baking sheet with parchment paper.
In a large bowl, whisk together the peanut butter, tahini, oil, maple syrup, molasses, and vanilla until smooth.
Add in the oats, nuts, seeds, coconut, hemp, cinnamon, and salt and stir until thoroughly combined.
Transfer to the baking sheet and spread out into an even layer. Bake for 15 minutes, then give the granola a stir to ensure even cooking. Spread it back into an even compact layer and bake for another 15 minutes.
Let cool completely (this is key!) before breaking into chunks, adding the freeze-dried berries, and storing.
