In a large bowl mix oat flour, pumpkin spice, and cinnamon until completely combined.
Add peanut butter, pumpkin puree, and maple syrup. Mix well until completely combined.
Line a 9x9" baking pan with parchment paper and press oat mixture in an even layer in the pan.
In a microwave-safe bowl, add chocolate chips and coconut oil. Heat in 15-30 second intervals until melted and smooth. Pour over the top of oat mixture.
Refrigerate for at least 2 hours to allow chocolate to harden and set. Slice into 16 even bars and store in the fridge.
