Preheat over to 400 degrees Fahrenheit, and lightly grease a square 9 by 9 inch bar pan with coconut oil.
Combine the pumpkin, coconut milk, egg whites, salt, cinnamon, pumpkin pie spice, vanilla, coconut sugar in a medium mixing bowl, and beat with a mixer until smooth.
Fold in the chocolate chips.
Pour the mixture into a 9" square bar pan, and bake at 400 degrees for 15 minutes.
Reduce the temperature of your oven to 325 degrees, then bake the bars for about 45 minutes more, or until a knife inserted in center comes out clean.
