Preheat your oven to 375°F (129°C). Line a large baking sheet with parchment paper and set it aside.
In a medium mixing bowl, combine the baking soda, salt, ground cinnamon, both coconut varieties, and both flours. Set aside.
In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl using a handheld electric mixer, beat the coconut oil, almond butter, and coconut sugar on medium speed until smooth and slightly fluffy, about 2 minutes.
Beat in the maple syrup, vanilla, and egg until well combined.
Beat in the bananas until combined.
Reduce the speed to low and gradually beat in the dry ingredients, mixing just until combined.
Turn off the mixer and fold in the chocolate chunks, if using.
Using a large cookie scoop, drop level rounds of the dough onto the prepared baking sheet, leaving 2 inches between each one.
Bake for 13 to 14 minutes, or until the tops are set and the edges are golden.
Cool the cookies on the baking sheet for 10 minutes before transferring them to a wire rack to cool completely.
