Preheat your oven to 350 degrees F. Grease a 9x13 baking dish with butter.
In a large mixing bowl, whisk together the all-purpose flour, whole wheat flour, pumpkin pie spice blend, baking powder, baking soda, and sea salt.
In a separate mixing bowl, whisk together the eggs, coconut milk, pumpkin puree, and brown sugar until smooth.
Add the wet ingredients into the dry ingredients. Fold together with a rubber spatula just until the dry ingredients have been moistened. DO NOT OVERMIX. Pour the batter into a greased 9x13 baking dish. Sprinkle the chocolate chips evenly over the batter. Then drizzle the almond butter over the batter. Use a toothpick or knife to swirl the almond butter into the batter.
Bake for 20-25 minutes until the pumpkin bars are just baked through and a toothpick inserted comes out clean.
Let cool, and enjoy warm or cold!
