Preheat oven to 350°F (175°C) and grease or line an 8x8 inch baking pan with parchment paper.
In a large bowl, whisk together the pumpkin puree, maple syrup, almond butter, egg, and vanilla extract until well combined.
Stir in the rolled oats, pumpkin pie spice, baking powder, and salt until the dry ingredients are fully incorporated.
Fold in the dark chocolate chips.
Transfer the batter to the prepared baking pan and spread evenly with a spatula.
Bake for 25 to 30 minutes or until the center is set and the edges are lightly browned.
Remove from the oven and allow to cool completely in the pan for at least 30 minutes before cutting into 12 squares.
