Preheat oven to 325 F. Line a baking sheet with a silicone baking mat and set aside.
In a small saucepan, combine the peanut butter, butter, and honey. Over medium-low, heat the mixture until melted and well incorporated, stirring constantly. Remove from heat and add the vanilla extract and cinnamon.
In a large bowl, mix together the oats and hemp protein powder. Pour the peanut butter mixture over the oats and stir until all of the oats are coated with the mixture.
Immediately, pour the mixture on to the Silpat covered baking sheet and bake for 15-20 minutes, until golden.
Allow to cool slightly before separating and spreading the granola into tiny clumps. Store in an airtight container.
