Preheat oven to 350 degrees F. Grease an 8×8 glass baking dish.
In a large bowl, whisk/mix together pumpkin puree, nut butter, eggs, maple syrup, and vanilla extract. Then fold in oats, pumpkin pie spice, baking soda, and salt. Lastly, fold in chocolate chips.
Pour mixture into the grease baking dish, spread out evenly, then place in the oven to bake for 40 minutes, until cooked through in the middle. Then cut into bars and serve up! They are DELIGHTFUL when served warm!
*If it is a dry almond butter or other seed butter, the oat bars can get a bit dry after baking
