Preheat oven to 350 degrees.
In a medium bowl, add the dry ingredients: whole wheat flour, buckwheat flour, almond flour, rolled oats, baking soda, and salt.
Stir the dry ingredients until combined.
In another bowl, add the coconut oil, zucchini, coconut sugar, egg, and vanilla.
Stir the wet ingredients until combined.
Next, fold the dry ingredients into the wet ingredients until a dough is formed and mixed through.
Fold in the chocolate chips.
Next, use a cookie scoop to add the cookie dough to a baking sheet in even rounds.
Place 12 cookies on each cookie sheet and place the cookie sheets to the oven and bake for 12 minutes or until the outside of the cookies start to golden.
Once the cookies are done, remove the cookie sheet from the oven and allow the cookies to cool for 10 minutes before removing them from the pan.
Store the leftover cookies in an airtight container.
