Preheat your oven to 350ºF. Line an 8x8-inch baking dish with parchment paper and give it a light spritz of cooking spray.
In a big bowl, mix together pumpkin puree, maple syrup, almond butter, eggs, and vanilla until it's all smooth.
In another smaller bowl, stir together almond flour, pumpkin pie spice, baking powder, and salt.
Combine the dry ingredients into the bowl with the wet ones, stirring until they just come together. Use a rubber spatula to gently fold in the chocolate chips.
Transfer this delightful mixture into the prepared baking dish and sprinkle some extra chocolate chips on top if you're feeling fancy.
Pop the pan into the oven and bake for 30 to 34 minutes, or until a toothpick inserted in the center comes out mostly clean. Let it cool in the pan for 30 minutes. Then, use the parchment paper overhangs to lift the bars out of the pan and let them cool completely before cutting them into 12 squares.
