Preheat the oven to 350°F and line a baking sheet with parchment paper.
Mix the maple syrup and peanut butter together. It should have a thick, but pourable consistency. Add 1 tsp of water at a time to thin it out if needed.
Mix the oats, protein powder, flax meal, chia seeds, cinnamon, salt, walnuts, cashews, raisins, and banana chips.
Stir in the peanut butter mixture and mix in thoroughly until all the peanut butter mixture has been spread evenly across the oats.
Spread the granola out evenly on the baking sheet and bake for 13 - 15 mins, mixing halfway through.
Let cool for 10 mins before eating.
Notes
Should last for about 1 month at room temperature in an airtight container.
