Preheat the oven to 350 degrees F and line baking sheets with parchment paper.
Combine the bananas, vanilla, and coconut oil; set aside.
In another bowl, whisk together the oats, almond meal, shredded coconut, cinnamon, salt, and baking powder.
Add the dry ingredients to the wet ingredients, and stir to combine. Fold in the chocolate pieces.
Using a measuring tablespoon, drop rounds of the dough an inch or so apart on the prepared baking sheets. Bake for 12-14 minutes, or until the cookies are golden.
Allow to stand for 2 minutes. Remove to a wire rack and cool completely.
