Preheat your oven to 350ºF (175ºC). Line or grease an 8×8 inch baking pan with parchment paper.
In a large mixing bowl, combine the eggs, pumpkin puree, maple syrup, coconut sugar, melted coconut oil, and vanilla extract. Whisk until well-blended and smooth.
Add in the oat flour, rolled oats, pumpkin pie spice, and baking soda. Stir gently until just combined; be careful not to overmix.
Gently fold in the chocolate chips into your batter.
Pour the batter evenly into your prepared pan and sprinkle some extra chocolate chips on top if desired. Bake for 24 to 26 minutes or until a toothpick inserted comes out clean.
Allow the bars to cool in the pan for at least 10 minutes before cutting them into squares.
