Preheat the oven to 350 °F and line a 9x9 inch baking dish with parchment paper or a silicone liner leaving enough overhang in order to be able to lift the bars out easily.
Add the pumpkin, almond butter, maple syrup, egg and vanilla extract to a large mixing bowl and mix.
Stir in the remaining ingredients until well combined.
Pour the mixture evenly into the prepared baking dish and bake for 24-27 minutes until they appear just set on top (they will still be quite soft).
Allow to cool completely in the pan for about 1-2 hours.
Remove the bars from the pan using the overhanging liner and move to a cutting board.
Slice into bars and enjoy!
